Model Number P0926EJ-0C
Product Line Foxboro I/A Series
Module Type DC/DC Power Distribution & Interface Module
Key Function Converts a centralized -48 VDC input into the regulated DC voltages needed for an I/A Series rack.
Input Specifications
Input Voltage -48 VDC (Nominal). This is a common voltage for centralized battery-backed power systems. The operating range is likely around -40 to -60 VDC.
Output Specifications
Output Voltages Provides the standard DC voltages required by the I/A Series backplane:
• +5 VDC (for digital logic)
• +15.2 VDC and -15.2 VDC (for analog circuits)
• +24.8 VDC (for field I/O power)
Total Output Power The "26" code suggests a specific power rating, which would be detailed in the data sheet (e.g., 260W or similar).
Protections Standard protections including input reverse polarity protection, over-current (OCP), and over-voltage (OVP) on outputs.
Physical & Operational
Mounting Installs into a dedicated slot in a Foxboro PSS rack (e.g., PSS21, PSS31).
Hot-Swappable This depends on the rack system design. In many PSS31 configurations, these modules can be hot-swappable. Verification from the manual is critical.
Status Indicators (LEDs) LEDs to indicate the presence of input voltage (-48 VDC) and output power status (DC OK).
Environmental
Operating Temperature 0°C to +60°C (standard industrial range).
The Foxboro P0926EJ-0C is a Power Supply Interface Module or Power Distribution Module for the Foxboro I/A Series Distributed Control System (DCS). Unlike the P0916JR0C, which is a full power conversion unit, this module's primary role is to distribute and manage power from an external, high-capacity DC power source to the various modules within a PSS (Power Supply System) rack.
