Product Description

The P0912XX is a specialized AC transmission power and transfer module designed for the Foxboro I/A Series Distributed Control System (DCS). It provides stable 120 V AC power to control processors and Fieldbus Modules (FBMs), ensuring continuous operation of critical DCS hardware.

Built for high-reliability industrial applications, the P0912XX acts as both a power distribution node and a transfer interface, enabling AC power switching or relay output functions as needed. Its rugged, compact housing is optimized for thermal stability, electrical isolation, and long-term operation within equipment racks or power distribution cabinets.

Technical Specifications

Application Scenarios

The P0912XX is commonly deployed in DCS power entry sections to ensure reliable power delivery to:

• Control processors and I/O subsystems

• Electrical utilities and water treatment plants

• Manufacturing facilities with 120 V AC control logic

It is particularly useful for systems requiring redundant AC feeds to maintain uninterrupted control system operation.

Technical FAQ

Q: Is the P0912XX a simple power supply or a transfer switch?
A: The P0912XX functions as a transmission power supply with switching capabilities, often managing AC power transfer between redundant sources to maintain continuous system excitation.

Q: Why is 120 V AC input important?
A: The 120 V AC rating aligns with North American and international industrial standards. The module converts or transfers this line voltage to the levels required by I/A Series backplane components, ensuring stable operation of controllers and FBMs.
