The DC-BCUI is a dual module consisting of a bus coupler and a watchdog CPU. It connects a substation via HiBus™ to the DC-BCUO bus decoupler module of a higher-level DC-Manager™ or LabManager.
The watchdog CPU continuously monitors CPU function, external activation power supplies, and ambient temperature. It activates the activation power supplies and, in the event of a fault, automatically performs a load shedding operation to bring connected outputs to a safe state.
This architecture offers high operational reliability through redundancy:
Both the higher-level system and the watchdog CPU can independently switch off the activated outputs as soon as a fault is detected.
The DC-BCUI module is used as a coupling assembly for another substation, making it ideal for the modular and flexible expansion of your laboratory and process systems.
