Foxboro P0973JX STK-RPS-150PS – Product Description

Overview

The Foxboro P0973JX STK‑RPS‑150PS is a high-reliability redundant power supply module designed for Foxboro distributed control systems. Moreover, its redundant architecture ensures continuous DC power delivery, automatically taking over if the primary supply fails. The compact modular design allows flexible installation in standalone mode or within two-slot or eight-slot racks. Built with industrial-grade components, this module provides long-term stability in harsh environments such as oil & gas, chemical, and power generation facilities. In addition, integrated diagnostics monitor voltage, current, and thermal conditions to reduce unexpected downtime.
