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:
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.
The Modicon 171CCC96030 is a M1/M1E Processor Adapter that is part of the Momentum Automation platform. It is compatible with a variety of software, including ProWORX NxT V2.0, ProWORX 32, Modsoft V2.5 and above, and Concept V2.6. It relies on an Ethernet protocol for its communication port, and also contains a I/O Bus port. The Ethernet port connector on this module looks like a Modbus port connector. Do not try to use an Ethernet adapter as a Modbus unit or attempt to place a Modbus connector in an Ethernet connector. The connectors and LED indicators are shown in the following diagram.
This processor adapter contains 3 LED indicators – RUN, LAN ACT(IVE), and LAN ST(ATUS). If the RUN indicator is Green and on continuously, the CPU has received power and is solving logic. If this indicator is flashing, then there is an error pattern if the CPU is in kernel mode. If this indicator is completely off, then the CPU is not powered up or solving logic. If the LAN ACT(TIVE) indicator is continuously on OR blinking, then this indicates activity at the Ethernet port. If the indicator is off, then there is no activity detected. The LAN ST(ATUS) indicator should be continuously green during normal operation. A fast blink indicates normal Ethernet initialization at power up. Three flashes on the LAN ST indicates that no 10BASE-T link pulse is detected and the cable and hub should be checked. Four flashes indicate that a duplicate IP address is detected, and five flashes indicates that no IP address is detected. If the LAN ST is off, then there is no valid MAC address.
It is important to note that the 984LL exec used in the 171CCC96030 will not operate in a 171CCC96020.
The 171CCC96030 has a variety of web services included. It contains a data editor, rack viewer, web page loader, and web page loader software tool. Its Ethernet services include I/O scannning and Modbus TCP messaging. The processor has 544 kB of RAM and 1MB of flash memory. With ProWORX software, it can process 80 I/O words per drop. With Concept, it can process 128 I/O words per drop.

The Magelis XBTGT7340 is an advanced touchscreen panel with with a backlit color TFT LCD display. It has a display size of 15 inches and a resolution of 1024 x 786 pixels XGA. The panel uses a Magelis operating system and a CPU RISC processor with a frequency of 266 MHz. It contains 512 kB of SRAM backup memory. It also has a slot for a compact flash card for 12 MB to 1 GB of additional storage.
The backlight lifespan on an XBTGT7340 lasts 50,000 hours, so it may be time for your panel to be repaired or replaced if you are experiencing display problems on an older unit.
The XBTGT7340 panel is equipped with a number of diagnostic features that can be used to check its system and interface for any troubleshooting issues. From the “Settings” menu, touch the “Offline” tab and then the “Self Test” icon to access these features. The Self Test checks the following functions: Character Pattern, Display Pattern, Touch Panel Cells, COM 1 & 2, and Video Memory. The message “NG” will appear on these tests if there is an error.
It is important that regular cleaning of the front panel and gasket is performed. When the surface of the display gets dirty, soak a soft cloth in little water with a neutral cleaning solution and wipe the display. The gasket on the XBTGT7340 protects the unit and improves its resistance to water. If the gasket has been in use for a long period of time, it may have scratches and debris on it, which can reduces the unit’s water resistance. Be sure to change out the gasket at least once a year, or if any visible damage or dirt is apparent on it.
The 6SL3244-0BB12-1FA0 is a Sinamics G120 Control Unit. This unit features a Safe Torque Off (STO) function that prevents energy from being supplied to the motor, which can generate torque. This function can be used in a number of ways. It can be used with an Emergency Stop button, so that when it is pressed, the stationary motor does not start. It can also be used with a central Emergency Stop button to ensure that several drives cannot unintentionally start. The module functions by recognizing the selection of STO via a fail-safe input or via the safe communication PROFIsafe. The converter then safely switches off the torque of the connected motor. If no motor brake is present, the motor coasts to a standstill. If a motor holding brake is in use, the converter closes the brake immediately after selecting STO.
The Safe Stop 1 (SS1) is another function of the 6SL3244-0BB12-1FA0. The SS1 function brakes the motor, monitors the magnitude of the motor deceleration within defined limits and initiates the STO function if the motor speed falls below a specified value. The SS1 function brakes the motor, and monitors its absolute speed. If the motor speed is low enough, the converter safely switches off the motor torque using STO.
The third function of the 6SL3244-0BB12-1FA0 is Safely Limited Speed (SLS). The SLS function prevents the motor from exceeding the defined speed limit. SLS monitors the absolute value of the actual speed and limits the speed to values below the monitoring threshold. The Safe Direction Function (SDI) prevents the motor shaft from moving in the wrong direction. It does this by monitoring the actual direction of rotation, and also limits the speed to values in the permissible direction. The Safe Speed Monitor (SSM) function supplies a safe output signal to indicate whether the motor speed lies below a defined limit. SSM cannot be selected or deselected, it is only active when monitoring velocity is > 0 for SSM. The converter then compares the load speed with the speed limit and signals if the limit value has fallen below the high-level control.
The 6AV6647-0AF11-3AX0 is a Simatic 477 HMI Basic Panel with a key and touch operation, and a 10 inch TFT display.
The panel has a Profinet interface, a RISC 32-bit processor, and contains open-source software which is provided free of charge. The 6AV6647-0AF11-3AX0 is best mounted vertically in a landscape position.
The 6AV6647-0AF11-3AX0 uses a 24V DC power supply, however its permissible voltage can range from 19.2V to 28.8V DC. The panel is intended for operation on grounded supply networks only, it is not designed for operation on ungrounded or impedance-grounded power networks. The permitted nominal voltage of the device must conform with the local mains voltage. The mains connector must be disconnected to completely isolate the device from the mains. It is helpful if easy access is left to this area during installation. The master mains disconnect switch must be installed in the device is mounted in a switch cabinet. Always and be sure to have free and easy access to the power inlet on the device or that the safety power outlet of the building installation is freely accessible and located close the device.
During 6AV6647-0AF11-3AX0 commissioning and its first start up, the Windows XP operating system on the Compact Flash card or hard disk is configured automatically. Follow the instructions on the screen, and then restart the system after you have entered all the necessary information and the operating system is configured. It is important to note that system startup may take longer than usual for the basic commissioning – it is normal for a blue screen to be displayed for several minutes. After this, when you switch on the PC, the user interface of the Windows XP Embedded operating system is automatically opened when the startup routine is completed.
It is advisable to create an image of your system partition after basic commissioning in order to prevent potential data loss.

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.
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.
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.
