Model Number P0916KH-0B
Product Line Foxboro I/A Series
Module Type Redundant, Hot-Swappable AC/DC Power Supply Module
Key Function Provides high-wattage, fault-tolerant power for high-density I/A Series nodes.
Input Specifications
Input Voltage Wide-range AC input, typically 90-264 VAC, automatically sensed.
Input Frequency 47 - 63 Hz (compatible with 50Hz/60Hz power grids).
Power Factor Correction (PFC) Active PFC (Power Factor Correction) is standard for high-power modules to meet efficiency regulations.
Output Specifications
Output Voltages Provides the standard, isolated DC voltages for the I/A Series backplane:
• +5.1 VDC (for digital logic circuits)
• +24.8 VDC (for field I/O power)
• ±15.2 VDC (for analog circuit power)
Total Output Power High Capacity, estimated 1600 Watts (based on the "16" suffix). The exact wattage per voltage rail must be verified.
Redundancy Designed for N+1 Redundancy. Modules operate in a current-sharing, load-sharing mode.
Protections Comprehensive suite including: Over-Current (OCP), Over-Voltage (OVP), Over-Temperature (OTP), and Short-Circuit protection.
Physical & Operational
Mounting Slides into a dedicated bay in a redundant power chassis (e.g., a PSS31 rack).
Hot-Swappable Yes. Designed for insertion and removal under full load without disrupting system operation.
Cooling Internal, forced-air cooling with fans. Fan status is typically monitored.
Status Indicators (LEDs) Comprehensive LED indicators for:
• AC Power Present
• DC Output OK
• Unit Failure
• Load Sharing Active
• Replace Indicator
Communication May include a communication link for reporting status, alarms, and metrics (e.g., output current, temperature) to the system for monitoring.
Environmental
Operating Temperature 0°C to +60°C (with derating at the upper end of the temperature range).
Efficiency High efficiency, typically > 85% or 90%, to minimize heat generation and energy loss.
The Foxboro P0916KH-0B is a High-Capacity, Redundant, Hot-Swappable AC/DC Power Supply Module for the Foxboro I/A Series Distributed Control System (DCS). It is designed to provide reliable, regulated DC power to high-density control racks that house a large number of power-hungry modules, such as control processors, communication cards, and extensive I/O networks.
