GE IC687BEM713 Genius Bus Interface Module for GE Series 90-70 PLC Controller Rack

Product Description

GR IC687BEM713 is a dedicated Genius bus master communication module for GE Series 90-70 PLC system. It acts as a bridge between CPU backplane and remote Genius distributed I/O 

stations, handling real-time data polling, signal mapping and fault diagnostics of multi-drop Genius field bus. Each module supports one independent Genius bus trunk, connects up to 32 Genius 

I/O blocks over twisted pair wiring, supports dual bus cable redundancy for uninterrupted field signal collection. Standard single-slot rack plug-in design, powered by rack backplane, widely used 

as maintenance spare for power, water treatment, manufacturing old GE PLC control cabinets.
