Description
The General Electric IC600RB752 is a Series Six Redundant Processor Unit (RPU) Device Switch Module engineered to facilitate peripheral sharing between dual redundant central processing units. This specialized hardware module incorporates twelve independent Form C reed relays, enabling external peripherals such as printers, CRTs, and communication links to dynamically switch between the master and backup CPUs based on active bus positioning. A front-mounted 36-point connector provides secure physical access to all relay signal terminals for external device integration.
In addition to peripheral switching, the module provides vital hardware isolation between the CPU and I/O switch architecture and the Data Control Module memory space within the RPU rack. It features an integrated watchdog timer, a seven-segment status display for instant system configuration and error code diagnostics, and onboard configuration jumpers that dictate data transfer parameters and scan time limitations. The unit slides directly into designated rack slots within legacy Series Six automation architectures.
