Allen-Bradley
PLC
Programmable logic controllers (PLCs) and I/O modules are at the heart of industrial control and input/output management in your installations.
Whether digital or relay output modules, or analog and temperature input cards, such as the Allen-Bradley SLC 500 modular system, they ensure reliable processing and execution of your production cycles.
Discover a wide range of refurbished PLC chassis, cards and modules, including parts no longer available from the manufacturers, to extend the life of your existing architectures without a complete overhaul.

FAQ
Input/output modules (1746 series) allow the PLC to interact with the field. Digital or relay output cards (1746-OB16, 1746-OW16) drive actuators, contactors and indicator lamps, while specific modules such as the 1746-NR4 take accurate temperature measurements via resistance temperature detectors (RTDs).
Faults most often show up as an output channel stuck high or low (welded relay or short-circuited output transistor), diagnostic LEDs on the card that don't light, drifting analog measurements or a communication fault on the PLC rack.
Yes, component-level repair restores obsolete modules (replacement of output relays, protection optocouplers, input filtering components or bus drivers). This avoids replacing the entire chassis and reprogramming your installation.
Every repaired or refurbished PLC card is installed in a dedicated powered test rack. We individually test all input/output channels under load, communication with the CPU and the diagnostic LEDs to ensure immediate operation in the cabinet.
