GE Fanuc IC660BBD023 Digital I/O Block

The GE Fanuc IC660BBD023 is a 16‑circuit sink‑type distributed digital I/O block of the Genius I/O series, designed for GE Series 90‑30 /90‑70 PLC systems. Each channel can be set as input, tristate input or output to connect 2‑wire and 3‑wire solid‑state sensors and actuators.

This field‑mounted intelligent I/O block communicates with the PLC main CPU via Genius bus. It has built‑in LED status indicators and comprehensive fault diagnosis functions. Original production has been discontinued, and it is widely supplied as aftermarket spare parts for maintenance and transformation of legacy distributed control systems.
