GE IC687BEM742-EB I/O Expansion Module

Series Affiliation: It is an I/O expansion module of the GE PACSystems RX7i Programmable Automation Controller (PAC), mainly used to expand the communication capability of the system or connect other I/O modules to realize distributed control.

Core Function: As a Bus Expansion Module (BEM), its core role is to expand the backplane bus of the RX7i system, allowing more I/O modules to be connected in remote or local racks, thereby enhancing the flexibility and expandability of the system.

Large-scale industrial production lines: Realize centralized control by expanding I/O modules and connecting devices such as sensors and actuators.

Distributed Control Systems (DCS): Act as a communication bridge between local and remote nodes to coordinate the control logic of various regions.

Process automation: Used in industries such as chemical industry and electric power to collect and control key process parameters.

During installation, ensure compatibility with the rack and CPU models of the RX7i series to avoid communication failures.

Strictly follow electrical specifications during wiring to prevent short circuits or poor grounding.

System configuration needs to be completed through GE's programming software (such as Proficy Machine Edition), including module address allocation and communication protocol settings.
