IC694BEM331 is an RX3i series Genius bus controller module produced by GE or Emerson PACSystems in the United States. The following is a detailed introduction to the IC694BEM331 digital module:

1、 Basic Information

Product model: IC694BEM331

Brand: GE/Emerson

Product Series: PACSystems RX3i

Type: Genius Bus Controller Module

2、 Main functions and features

Data exchange capability:

This module is capable of exchanging up to 128 bytes of data with each Genius I/O device and receiving 128 bytes of global data.

In the RX3i system, up to eight IC694BEM331 modules can be installed.

Connection and Communication:

Mainly used to connect PACSystems RX3i and Genius serial I/O bus.

Support data exchange through Genius blocks, PLCs using Genius bus controllers, remote I/O drops, VersaMax, and on-site distributed I/O.

Supports communication between global data and datagrams, with a maximum of 128 bytes of global data sent and received per bus scan.

Fault diagnosis and reporting:

Genius blocks and other devices on the bus will automatically report faults, alarms, and certain other predefined conditions to the bus controller.

The bus controller will store any diagnostic information received, and the CPU will automatically read this information and display the fault in the fault table through programming software.

Indicator lights and status monitoring:

The LED indicator lights on the front of the bus controller (such as OK and COM) display its operating status for easy fault diagnosis and monitoring.

Transmission speed and compatibility:

Supports 153.5Kbaud standard/extension, 76.8KBaud or 38.4KBaud transmission rates, which can be configured through software.

Compatible with GE 90-30 series and 6 series PLC systems.

Physical characteristics and electrical specifications:

The rated voltage is 5V DC and the rated current is 300mA.

The isolation rating is 2000 volts, and the transient common mode rejection isolation rating is 1500 volts.
