PRODUCT INFORMATION
Product Overview
The General Electric IC697BEM711 is a Series 90-70 Bus Receiver Module designed for PLC rack expansion. This module operates within an IC697 PLC system to connect downstream expansion racks. It allows engineers to install additional input, output, and specialty modules across the automation architecture. The unit supports expansion configurations reaching up to seven expansion racks. Data communication across the parallel expansion interface operates at 500 kilobytes per second.
The IC697BEM711 features two front 25-pin D-shell data connectors for daisy-chain cable connections. Port 1 connects towards the CPU rack or preceding bus interface module. Port 2 extends the communication line away from the CPU toward additional racks. System fault isolation separates rack communication, simplifying targeted troubleshooting during service operations. An output hold function permits modules in a disconnected rack to retain their last operating state. The module occupies a single slot and draws 800 mA at 5 Volts DC backplane power.
