Core Functions
Centralized power supply for DCS rack
Provides stable and clean 24V direct current working power for AC800M controller, CPU card, various I/O modules, and communication board cards.
1+1 redundant hot standby operation
Two PSM0004 boards operate in parallel redundancy. When a single power supply fails or is disconnected, the other board seamlessly takes over all the load and supports online hot swapping without requiring downtime or power interruption, ensuring continuous operation of key power plants and chemical plants without interruption.
Panel status diagnosis
On-board power operation and fault LED indicators for quick location of input phase loss, over-temperature, short circuit, backplane abnormalities, etc., facilitating rapid on-site maintenance.
Multi-scenario compatible power supply
Can independently supply power to small racks with a single module, or redundantly deploy with two modules in key safety control cabinets.

Typical Application Scenarios
ABB System 800xA, AC800M DCS control system for boilers, turbine generators, excitation systems in thermal power plants
Petroleum refining, coal chemical, chemical process control cabinets
Metallurgy, cement, papermaking, rail transit large-scale industrial automation control systems
Self-owned power plants, waste incineration plants FSSS furnace safety monitoring system, SIS safety instrument system power supply
