Repair Allen-Bradley 1771-IB PLC-5 DC Digital Input Module

The Allen-Bradley 1771-IB PLC-5 DC Digital Input Module converts DC signals provided by other user devices to a processor's logic level, and controls the state of corresponding bits in the PLC data table. A 1771-W wiring arm is including for replacing the module, removing the need to disconnect the wiring. The module supports 1/2, 1, and 2-slot I/O addressing, and is compatible with source-switching devices such as dry-contact switches, electro-mechanical transmitters, and panel-switching devices such as selector switches and pushbutton.

Eight red status indicators for field side indication exist at the front panel. The module contains opto-electrical isolation to protect the system circuits from electrical transients.
