900PSM-0001 Honeywell Controller Redundant Power Status Module

The Power Status Module (PSM) is an essential component in local or remote I/O racks equipped with redundant power supplies. It is housed in a rack extension assembly next to the power supply slot, placed in a dedicated slot between the two power supplies to ensure optimal functionality and monitoring.

• Controller Rack with Local I/O: Ensures continuous power supply for local I/O operations.
• Scanner 1 Rack with Remote I/O Controller Racks (Non-redundant Systems): Supports non-redundant remote I/O systems.
• Scanner 2 Rack with Remote I/O Racks (Redundant Systems): Enhances the reliability of redundant remote I/O systems.

The PSM features directional indicators that provide visual feedback on the status of the power supplies using green directional LEDs to indicate the proper operation of both voltage sources.
