Functional Features: Provides stable DC power to I/O packs and controllers. Supports online replacement (hot-swap) in redundant pairs without interrupting control logic.

Application Scenarios: Turbine control, balance-of-plant control, and distributed control systems requiring high availability.

Working Principle: Switch-mode power conversion with active current sharing for redundancy. Internal diagnostics monitor output health and report faults to the controller.

Precautions: When replacing a failed unit in a redundant setup, ensure the replacement module is the exact model (G2A) and firmware level. Verify tight seating in the rack connector.
