The P0922YU (Model FPS400-24) power module is utilised extensively in Foxboro I/A Series and Foxboro Evo™ distributed control systems (DCS). The primary application of this power module is to provide a 24Vdc power source to the fieldbus module (FBM), the controller baseplate, and associated industrial devices.
The main functions are as follows:
Convert an input power supply (either AC or DC) to a stable 24Vdc output,
Provide power to the FBM, communications, and control units,
Provide power protection and isolation at a system-wide level.
Help run the distributed control system.
Operating temperature: -40°C to +70°C
Storage temperature: -40°C to +85°C
Humidity range: 5% – 95% (no condensation)
Altitude: -300 ~ 3000 meters
Protection level: G3 (for harsh industrial environments)

Why choose FPS400-24 P0922YU Power Supply
The FPS400-24 Power Supply supports both AC and DC input power supplies, which can be used in various industrial power supply environments, thereby enhancing the adaptability of the system's power supply.
01
The FPS400-24 Power Supply is equipped with a built-in dual-level current limiting mechanism. When the load current exceeds the rated range, it will automatically limit the output, thereby protecting the equipment and preventing system damage.
02
When the output voltage abnormally rises, the FPS400-24 Power Supply will automatically enter a protection state and shut off the output, which helps to prevent the downstream modules from being subjected to voltage shock.
03
The equipment adopts a natural convection cooling design, which enables it to operate without the need for fans. This helps to reduce maintenance requirements and minimize failure points.
