Product Description

Description

The General Electric IC600RB751 is a legacy Series Six CPU/RPU Switch Module designed for industrial automation applications requiring redundant processing architecture. This hardware component plays a critical role in managing master and backup operations within a Series Six rack system by routing control signals effectively across the backplane.

The module functions by selecting either the primary or secondary CPU I/O bus—as determined by the Data Control module—and securely connecting the active bus to the designated I/O switch module. Equipped with reliable solid-state switching architecture, the IC600RB751 ensures smooth, bumpless transfer of I/O chain control between processors to maintain continuous process operation.

Features

  • Solid-state bus switching design allows for bumpless transfer of I/O chain control between dual CPUs.
  • Interfaces directly with standard multi-conductor I/O bus cables via integrated 37-pin D-type connectors.
  • Engineered specifically for legacy General Electric Series Six rack and backplane environments.
  • Supplied as a complete functional assembly including the circuit board and front faceplate.

Applications

  • Redundant General Electric Series Six PLC system architectures
  • Complex discrete manufacturing and continuous process control
  • Legacy industrial automation system maintenance and rack upgrades

Technical Specifications

Parameter Specification
Manufacturer General Electric
Product Number / SKU IC600RB751
Product Family Series Six
Module Type CPU/RPU Switch Module
Internal Power Requirement 5 VDC at 2.0 Amps
Field Termination 37-Pin D-Type Connectors
Switching Mechanism Solid-State Bus Switch
Country of Origin United States

Connections / Interfaces

The module features front-accessible 37-pin D-type connectors intended for the termination of standard multi-conductor I/O bus cables. Internal connections interface directly with the Series Six rack backplane to route signals between the Data Control module, the CPUs, and the selected I/O chains.

Installation Guidelines

Ensure that all rack power is completely disconnected before inserting or removing the IC600RB751 module to prevent electrical shock or damage to internal circuitry. Slide the module carefully along the designated Series Six backplane guide rails until it seats firmly into the rear connectors, then secure the top and bottom faceplate retention screws.
