Description
Product Description
The IC694MDL634 is an 8-channel discrete input module designed for the GE Fanuc RX3i PACSystem. It supports both positive and negative logic and provides optical isolation between the field devices and the PLC backplane. Each input has an LED status indicator, allowing for quick diagnostics of discrete signals such as switches, sensors, and push buttons. The module operates under industrial-grade conditions and fits into any RX3i I/O slot, making it ideal for scalable system expansions.
