Benefits of Buying Refurbished Industrial Automation Equipment

At MRO Electric and Supply, we offer a wide range of 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:

1. Availability
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.

2. Price
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.

3. Equivalence
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.

4. Reliability
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.

Enhance System Performance with Modicon Quantum I/O Modules

Substation I/O modules for direct 125 Vdc control
Quantum I/O modules are available for direct connection to critical 125 Vdc battery powered equipment such as circuit breakers, protective relays, transformers and capacitor banks.

  • Built-in high transient noise immunity ensures reliable operation in harsh 125 Vdc environ- ments.
  • The 125 Vdc 30A high current output module eliminates expensive high current interposing relays used in breaker tripping and closure.
  • The solid-state 125 Vdc low current output module ensures long life and trouble-free operation in higher frequency 125 Vdc switching environments without the use of expensive external snubbing circuitry.
  • Over-current/ short circuit diagnostics and protection on all solid state 125 Vdc outputs reduce downtime by ensuring quick identifi- cation of circuit prob- lems and fast repair.
Special Purpose Module Characteristics
Latch/Interrupt module for time critical applications
The Quantum Latch/ Interrupt module is a multi-purpose high speed input, latch,
and interrupt module combined, which is configurable through programming software. Interrupt handling instructions are part of the 984 Ladder Logic instruction set. Quantum throughput performance for 2 interrupts is typically 1ms.
High speed counters don’t miss a pulse
Quantum high speed counter modules have the ability to count pulses at speeds much faster than the Quantum controller can directly do by itself. These modules automatically report the current count to the Quantum controller every scan.
Simple ASCII exchanges
The Quantum ASCII module is a general purpose ASCII interface that provides the ability to communicate and ex- change data with devices including printers, bar code readers and scanners, weigh scales, and meters. This module is designed for relatively simple point to point ASCII communications, with ASCII messages stored inside the module triggered by logic within the Quantum controller.

Sinamics 6SL3040-1MA01-0AA0: Beyond the User Manual

The Siemens 6SL3040-1MA01-0AA0 is a Sinamics Control Unit CU230-2 PN. It is designed for use with several drives. It is a control central modules in which the closed-loop or open-loop functions are implemented for one or more line modules and/or motor modules. The number for VFD drive depends on the required performance, the required additional functions, and the required operating mode (servo, vector, or U/f). The software and parameters are stored in a plug-in memory card, and the option slot can be used to expand the number of terminals or adapt other communication interfaces to the higher-level control.

6SL3040-1MA01-0AA0
6SL3040-1MA01-0AA0

If your application requires more than one control unit, the number can be increased accordingly and interconnected via the Profibus. The 6SL3040-1MA01-0AA0 communicates with its associated components, like motor modules, line modules, sensor modules, and terminal modules, via the internal system’s DRIVE-CLiQ interface. The module has 12 isolated digital inputs, and 8 non-isolated digital inputs/outputs.

With the 6SL3040-1MA01-0AA0, an open input is interpreted as “low”, and terminal M1 must be connected so that the digital inputs (DI) can function. This can be completed by either providing the ground reference for the digital inputs, or by using a jumper to terminal M. If at any time the 24V power supply is briefly interrupted, the digital outputs are deactivated. If at any time the memory card is withdrawn or inserted while the 6SL3040-1MA01-0AA0 is in operation, then data can be lost and a plant standstill could occur. Only withdraw the memory card when the control unit is in a no-voltage condition. Electrical fields and electrostatic discharge can also result in the memory card being damaged, so observe ESD regulations when handling it.

Modicon 140AVI03000

Modicon Quantum 140AVI03000 – Product Spotlight

The 140AVI03000 is a Analog Mixed Current/Voltage Input Modules that is part of the Modicon Quantum series. This Analog In 8 Channel Bipolar Modules accepts a mix of current and voltage inputs. Jumpers are required between the input and sense terminals for current inputs. The 140-AVI-030-00 contains a total of 18 LEDs. The “Active” LED remains on and green when Bus communication is currently present. The “F” indicator will light up red when an error external to the module has been detected. The green LEDs 1 through 8 will turn on when the indicated point or channel is ON. The red 1 through 8 LEDs when light up for two reasons. Either the indicated channel is out of range (1 – 5 Volts), or a broken wire condition has been detected (4 – 20 mA).

To prevent improper fault indications, unused inputs should have the + (plus) and – (minus) inputs tied together and be configured for a bipolar input range. Unwired inputs can cause invalid readings. When configured for voltage inputs (no jumper is installed between Input (+) and ISENSE terminals), a broken field wire can cause readings to be non-zero and unpredictable. The field wiring terminal must not be removed when the module is in operation.

The following figure shows the 140-AVI-030-00 Wiring Diagram.

140-AVI-030-00 wiring diagram
140AVI03000 Wiring Diagram

For external wiring, the user should supply the current and voltage sources, and installation and calibration of the fuses are at the discretion of the user. It is recommended that shielded cables are used, and twisted shielded cables should be used in noisy environments. The shielded cables should be connected to the PLC’s ground. A shield bar should be used to connected the shielded cable to the ground. If you are field wiring the 140AVI03000, the maximum wire size is 1-14 AWG or 2-16 AWG and the minimum wire size is 20 AWG.

Siemens Micromaster 420 Faults and Alarms

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully this helps with your troubleshooting.

Yaskawa V1000

Yaskawa V1000 – Compact Vector Control Drive

The Yaskawa V1000 is a compact current vector drive with dual microprocessor logic. There are 3 primary models: 200V 3-Phase Input, 200V Single-Phase Input, and 400V 3-Phase Input.  It is possible to run the drive without connecting the digital I/O wiring.

It is important when installing Yaskawa V1000 drives that proper electrostatic discharge (ESD) procedures are taken. Failure to comply could result in an ESD discharge that could damage the drive circuitry. If the drive is being operated at low speeds, the cooling effects are diminished and motor temperatures can increase which can lead to overheating. Continuously operating an oil-lubricated motor in the low speed range may result in burning.

A dynamic braking resistor can be used with the V1000 series. Dynamic braking helps bring the motor to a smooth and rapid stop when it is working with loads of high inertia. As the drive lowers the frequency of a motor with high inertia connected, regeneration occurs. This can cause over-voltage when the regenerative energy flows back into the DC bus capacitors. A braking resistor can help prevent these overload errors from occurring.

The drive functions are devided into 2 primary groups that are accessible through the Yaskawa V1000’s digital LED operator. Drive mode allows for motor operation and parameter monitoring. Parameter settings cannot be changed when functions are accessed in drive mode. However, alarm information and history can be accessed in drive mode. Programming mode allows access to the setup. There you can adjust and verify drive parameters as well as Auto-Tuning. The drive will not allow motor operation changes such as start and stop when the LED is accessing a function Programming mode. The V1000 is set to Drive mode when it is first powered up. The Up and Down arrow keys can be used to switch displays.

Modicon 140CRA31200 RIO Drop E/IP Adapter – Product Spotlight

The 140CRA31200 is a Ethernet RIO drop adapter in the Modicon Quantum series. It has 3 ports and uses the Ethernet IP/Modbus TCP communication port protocol. It can handle two integrated connection types: the Ethernet IP/Modbus TCP through the service port or through the device network. It is compatible with the 140CRP31200.

The 140CRA31200 has a number of local signalling channels. 1 green LED for RUN, 1 green/red LED for module status, 1 green/red LED for network communication status, and 1 red LED for I/O. This adapter module consumes one slot in the main (first) rack of the in Quantum remote drops. The extended (second) rack in a Quantum remote I/O drop does not require an adapter.

To set the location of the Ethernet remote I/O drop on the network, use the rotary switches on the front of the 140CRA31200 before you apply power to the module and before you download the application. The values that are set are applied during a power cycle. If the switch settings are change after the module has powered up, the Mod Status LED is activated and a mismatch message is logged in the module’s diagnostic system.

Because new values on the rotary switches are implemented on at the next power cycle, it is recommended that you set the values before starting the module. Valid values are from 00 to 159. These rotary switches can be manipulated on the 140CRA31200 with a small flat tipped screwdriver, and no software is required to configure or enable the rotary switches. Do not use the Stored and Clear IP settings on the Ones rotary switch, and keep in mind that the functionality of these settings do not apply to remote I/O installations.
