P0916KN power supply module

The P0916KN is a power supply module developed by Foxboro , specifically designed for powering modules in the Foxboro I/A Series Distributed Control System (DCS). It provides stable and reliable DC power to field bus modules (FBMs) and other DCS components, serving as a critical energy supply unit for the normal operation of industrial control systems. Below is its detailed information:

1. Core Functions

Stable DC Power Output: Converts input AC power into regulated DC power to meet the power requirements of I/A Series DCS modules (e.g., FBM analog/digital modules), ensuring consistent voltage supply for signal acquisition and control.
Overload & Short-Circuit Protection: Integrates built-in protection circuits. It automatically limits output current when overloaded and shuts down temporarily in case of short circuits, preventing damage to the module itself and connected DCS components.
Redundancy Support: Typically deployed in pairs for 1+1 redundancy. If one P0916KN module fails, the other takes over immediately without interrupting power supply, enhancing the reliability of the DCS power system.
Status Monitoring: Provides real-time power status feedback (e.g., normal operation, overload, fault) via LED indicators on the front panel. It also transmits fault signals to the DCS for remote monitoring and troubleshooting.
