Industrial P-HC-BRC-PBA20000 Processor Bus Adapter

ABB Bailey P-HC-BRC-PBA20000 Symphony Processor Bus Adapter is a Processor Bus Adapter (PBA) module for the Bailey Infi90/Harmony/Symphony control system. It provides the Hnet-connected PBA interface that links the Harmony/Symphony processor network to the processor bus, enabling communications between the central controller and field modules and supporting redundant configurations. The unit runs from 5 V DC and draws about 0.12 A (roughly 0.6 W); its enclosure measures 6.0 in L x 3.0 in W x 6.0 in H (about 15.2 cm x 7.6 cm x 15.2 cm) and weighs around 0.2 kg. Used in Bailey Infi90 installations, this PBA20000 part is referenced as the Symphony Processor Bus Adapter for Hnet connections, and is commonly deployed to expand or connect the processor bus within industrial process control networks.
