At MRO Electric and Supply, we offer a wide range of repaired, refurbished and reconditioned automation products for each of our manufacturer lines. We never supply used, untested, second-hand parts. Each of our refurbished parts is fully cleaned, serviced, functionally tested, and upgraded to optimal working order before being made available for sale. We also place each of our reconditioned products in like-new packaging for easy identification, transportation, and storage.
Benefits of Refurbished Automation Products:
For many obsolete and legacy automation product lines, finding new, unused parts can be a challenging task. Oftentimes, searching for unavailable new parts can cause unreasonably long lead times which increases the risk of downtime. MRO Electric stocks a variety of refurbished products with same-day and next-day shipping options, while keeps the risk of downtime to a minimum.
Refurbished products tend to be significantly less expensive than new parts. MRO Electric offers many refurbished items for up to 75% less than their new counterparts. This deep discounting allows our customers to stock up on spares while minimizing their costs.
Purchasing an exact replacement prevents compatibility issues versus upgrading to a newer component. For some manufacturers, it is better to stick with tried and true systems than risk purchasing a different part that may not function correctly with their process.
Just because a part has been refurbished does not mean that it won’t last as long as new. Additionally, many of our refurbished parts have seen little or no use throughout their lifetime. We are extremely confident in the reliability of our refurbishment process, and warranty all of our products for a minimum of 12 months.

Human Machine Interfaces, or HMI’s, are used extensively throughout the world to control and monitor automated machinery. These devices provide touchpad and visual interaction to control manufacturing processes and perform daily tasks. One of the most recognized HMI devices is the Automated Teller Machine (ATM). These ATM devices intuitively interface with users through a keypad and monitor to readily transact bank deposits and dispense cash withdrawals. They provide reliable 24-hour access to our daily banking needs.
Various HMI devices are common throughout industry. Many older HMI devices contain the original Cathode Ray Tube (CRT) monitor technology. This older technology burdens the users and owner with several disadvantages:
- High Energy Consumption – The CRT technology is not considered energy efficient. It requires more power to operate than the newer LCD technology. CRT screens consume 3 – 4 times the energy when compared to the LCD screens.
- Expensive to maintain – CRT repairs are becoming more specialized and expensive as the workforce transitions to the newer technologies.
- Obsolete Components – CRT technology is outdated and beyond its life cycle. Components required to support repair are becoming obsolete and expensive if available.
- Avoid costly new operator interface packages – MRO upgrades to LCD technology maintain the interface packages with your existing equipment (frames, communication connections, power sources, etc.). Updated HMI’s from MRO are plug-n-play.
- Better Reliability – Heat generated by the CRT technology often shortens the life of the electrical circuit components. CRT monitors tend to have a life of 18,000 to 20,000 hours. LCD monitors provide more than 100,000 hours life.
- Clarity of Picture, Crisp Image – LCD’s make the screen burn often associated with CRT’s a thing of the past. LCD image display is much clearer for the operator and will not fade.
MRO provides an HMI service to update your old CRT displays to LCD technology and new keypads. This approach is a low-cost upgrade to superior technology with no risks. Visit our repair page, call us, or email us for an instant quote on fixing, swapping, or purchasing your new HMI device.

Before we get into the differences of a PLC’s and DCS’s, we need to talk about what each of them are designed to do.
What is a PLC?
A PLC, or Programmable Logic Controller, is a computer that has been adapted to specifically meet the needs of any specific manufacturing process. These devices come in many different shapes and sizes, with many options for digital and analog I/O, as well as protection from high temperatures, vibration, and electrical noise. The invention of the PLC allowed computers to be streamlined into the industrial automation process.
A PLC can be a single device calculating and executing operations, or a rack of different modules may be used to meet whatever your automation system requires. Some of the additional components include processors, power supplies, additional IO, interfaces, and much more. Every part works together to be able to run open or closed loop operations that are rated at high speed and high precision. Take a CNC machine for example; a PLC would be used to control positioning and motion, as well as torque control. These devices are popular because they are very inexpensive relative to the amount of power and how many hours you get out of them.
What is a DCS?
A Distributed Control System is an automated control system that streamlines the functionalities of the various devices that are used throughout an entire work space. This type of system uses many different controllers to allow all the machining parts to talk to each other as well as computers that can input parameters and display information such as power usage, speed, and much more. These controllers are distributed geographically across a plant to allow for high-speed communication to the control room. When using different types of modules however, the system may require different communication standards such as Modbus and Profibus. DCS’s started coming to fruition throughout the 1960’s once the microcomputer was brought widespread into the market.
Then what exactly is the difference?
A PLC will probably be used to control a machine that isn’t too complex wheres the DCS can have total control of all the operations in an entire plant. The PLC is preferred in situations where the machine does not have to worry about meeting specific conditions inside the plant. These conditions typically involve operations that may need to stop or restart, as well maintaining precise temperatures. A DCS will be able to take advantage of all the aspects of an automated system, from the machines and sensors to the controllers and computers. An entire DCS is much more expensive than a few PLC’s, but each have their advantages in any given situation and certain automated systems will always require one over the other.

The E76/77 family of controllers are very compact and used for smaller robot arms. One of these arms are the RS003N Robot, which has a maximum payload of 3kg and has horizontal and vertical reaches of 620mm and 967mm, respectively. The controllers with these robots specialize in assembly and material handling applications.
The E9 family of robotic teach pedants are also built very compact, however these devices are typically used in medium-duty applications. Unlike the other two families of controllers, the E9 family features an open structure system with a direct cooling system. However, like the E7 and E3 families, the enclosed structure with indirect cooling is an available option. The E9 family takes full advantage of the digital servo drive powering it to have a maximum payload capacity of 40kg.
E30/32/33/34 controllers at their base are very alike the E76/77 controllers but with more power. These devices are not as compact as the previous devices we have discussed, however the reason being they are highly expandable and are easier to maintain. Features such as Kawasaki’s K-Logic sequencer software allow the addition of up to 16 total controllable axes. The E3 family of Kawasaki e-controllers are able to handle the following maximum payloads:
- E30 – 145 kg
- E32 – 180 kg
- E33 – 195 kg
- E34 – 180 kg

Yaskawa Motoman, an American subsidiary of Yaskawa Electric Corporation, was founded in 1989 and since then have been able to get over 380,000 industrial robots, 10 million servos, and 18 million drives into automation systems around the world. Robots are the wave of the future and Yaskawa Motoman is at the top of this market. Using an automated robotic system in your work space will allow you to free up many other costs and resources that may not have been available before. The key to efficiency is simplicity and using Motoman Teach Pendants to give instructions to your robot makes that possible.
Teach Pendants are non-tethered devices that allow your robot to be controlled remotely. These devices are crucial for industrial robotics as they are not only used for assigning operations but they are able to edit commands, emergency stop commands, and even view past operations. Motoman Teach Pendants are split between the older models(ERC, XRC, MRC) and the newer models(DX and NX Series’).
The older models such as the MRC, which came out in 1994, were able to increase the workload of an industrial robot by up to 300%. This was also the first time ever that a single teach pendant was able to control two robots at the same time. Four years later when the XRC model was released, it was a huge improvement as Motoman was able to add control of more axes and even up its synchronous control of two robots to four industrial robots.
Later in 2004, the NX series of controllers was released. These devices featured Windows CE with a high-power processor, back-lit color touchscreen, built-in ethernet, and a huge amount of memory. A single teach pendant can control up to 36 axes and 4 separate robots. It’s Advanced Robot Motion control allows for the most accurate results. For information about the DX series, please visit one of our previous blog posts featuring the DX200 controller and Yaskawa’s new ArcWorld project.
Yaskawa’s ArcWorld 6000 line of robotic welding systems offer the most cost efficient and powerful solution to your welding needs. ArcWorlds are pre-built, easy to install, and ready to run immediately after installation. The units can configured with multiple robots, a heavy duty positioner or servo controlled external axes. The 6000 line can handle payloads from 755 kg to 1255 kg over a 2 or 3 meter span. There are many other cool benefits to running the ArcWorld over a traditional welding system:
- All controllers and power sources are installed and shipped on the frame for minimal setup
- The world class MA1440 arc used for welding can be combined with multiple robots to cut cycle time by 15%
- Twist locking connectors for all cabling
- Fully compliant with most recent robot safety standards (ANSI/RIA R15.06-2012)
- A standard workcell is only documented and supported by Yaskawa Motoman
The RM2-Series Positioners are are powered with three AC servo motor drives and have a payload capacity of 1555 on each side. With a 6.5 second rapid indexing time, the positioners have a part length between 3000mm and 3500mm. Convenient slip ring built for the fixture of utilites such as Ethernet and DeviceNet. The positioner uses MotoMount mounting technology inside of the Yaskawa ArcWorld Unit.
Typically used inside of the ArcWorld 6000 line is the DX200 controller. These controllers can coordinate motion between 8 robots with up to 72 axes. Its Advanced Robot Motion control gives the ArcWorld unit the ability to use the arc’s at their peak performance with pinpoint precision. DX200 controllers are available with Cat 3 Functional Safety Unit. Maintenance is hardly necessary as these controllers efficiently use energy and use top of the line prevention methods for most types of failures. Contact Yaskawa Motoman right now to inquiry on price options for different ArcWorld models and make your automation system perform at its best.

Electronically coordinated single-motor drives work in unison to perform your all of your drive needs. In multi-axis drives, the individual drives are controlled from a higher-level control system in a way to achieve the desired coordinated movement. A centralized Siemens SINAMICS Control Unit has control over the drives for all connected axes and also establishes the links between the drives and/or axes. Since all required data is stored in the central Control Unit, it does not need to be transferred. The CU310-2 is used in conjunction with power modules and single-motor drives whereas the CU320-2 is used with all motor modules or line modules for both single and multi-motor drives.
Different versions of these control units include:
All of these control units are based on an object-oriented SINAMICS software called SIMOTION. The firmware included contains all common control modes and can be scaled to meet almost all automation requirements. This firmware will contain instructions for infeed controls for main infeeds, and all vector an servo controls.
