The GE Fanuc IC687BEM713B is a Bus Interface Module (BIM) designed for the Series 90-70 PLC architecture. It serves as the critical communication link between the PLC rack and the high-speed Genius I/O network. This module enables the Series 90-70 system to exchange data with distributed I/O blocks across a plant floor, allowing for centralized control of geographically dispersed equipment such as actuators, sensors, and remote motor starters.

Technical Specifications

Operational & System Features

• ⚙️ System Compatibility: Designed for use with Series 90-70 baseplates; acts as a bridge to the Genius I/O bus protocol.
