P0916JP power supply module

The P0916JP is a power supply module developed by Foxboro , specifically designed to provide stable and reliable DC power for modules in the Foxboro I/A Series Distributed Control System (DCS). It serves as a critical energy supply unit to ensure the normal operation of field bus modules (FBMs) and other DCS components in industrial environments. Below is its detailed information:

1. Core Hardware Parameters

Input Voltage: AC 100-240V (wide voltage range, 50/60Hz), compatible with global industrial power grids and eliminating the need for additional voltage adapters.
Output Voltage: Regulated DC 24V, with voltage ripple ≤50mV to avoid interfering with sensitive analog signals of FBMs (e.g., FBM201, FBM207).
Output Current: Maximum 10A, capable of powering multiple FBMs (e.g., 8-10 standard analog/digital modules) in a single I/A Series DCS rack.
Efficiency: ≥85% (high energy efficiency reduces heat generation, suitable for long-term operation in control cabinets with limited ventilation).
Physical Dimensions: Standard I/A Series rack-mount size (approx. 48.3mm width × 177.8mm height × 228.6mm depth), ensuring compatibility with existing DCS rack enclosures.
Weight: Approximately 0.8kg (lightweight design simplifies installation and rack load management).

2. Functional Features

Overload & Short-Circuit Protection: Built-in protection circuits automatically limit output current when overloaded and temporarily shut down in case of short circuits, preventing damage to the module and connected DCS components.
Redundancy Support: Designed for 1+1 redundancy deployment. When paired with another P0916JP module, the backup unit takes over immediately if the primary module fails, ensuring uninterrupted power supply for critical processes.
Status Monitoring: Front-panel LED indicators (e.g., "Power On," "Normal Operation," "Fault") provide visual status feedback. It also transmits fault signals (e.g., overload, input voltage anomaly) to the DCS for remote monitoring and troubleshooting.
Isolation Performance: Input-to-output isolation ≥2500V AC (1 minute) and output-to-ground isolation ≥1500V AC (1 minute), effectively preventing ground loops and electromagnetic interference (EMI) from affecting power quality.
