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).
