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.

| 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 |
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.
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.
