System Architecture & Signal Flow
The POM-RBH 33029692-1 operates within the HITACHI modular I/O architecture as a relay output interface board. Control signals from the CPU or I/O controller are received via the backplane bus, processed by onboard relay driver circuitry, and switched through isolated relay contacts to field devices. The board supports standard DIN-rail or rack-mount installation within HITACHI system enclosures. Signal flow: CPU/Controller → Backplane Bus → POM-RBH Relay Driver → Isolated Relay Contacts → Field Device.
