FOXBORO RH928AW | I/A Series Relay Output Module

FOXBORO RH928AW | I/A Series Relay Output Module

Product Overview

The FOXBORO RH928AW stands as a critical component in Foxboro I/A Series distributed control systems (DCS), functioning as a high-performance relay output module that bridges control logic with field devices.

As a key industrial automation spare part, it converts low-voltage control signals into robust switching actions, activating valves, motors, and alarms in demanding industrial settings.

Designed to integrate seamlessly with Foxboro’s I/O subsystems, the FOXBORO RH928AW plays a vital role in regulating processes where precision and reliability are non-negotiable.

Engineers typically mount the module in control cabinets alongside I/A Series FBM (Field Bus Module) interfaces, ensuring close coordination between the DCS and field equipment.

For example, in a natural gas processing plant, the FOXBORO RH928AW controls emergency shutdown valves, activating them within milliseconds when pressure sensors detect anomalies—preventing potential safety hazards and costly leaks.

The FOXBORO RH928AW combines rugged construction with intelligent design to excel in industrial control.

Its 8 independent relay channels support versatile configurations, allowing control of multiple devices—from small solenoid valves to larger motor starters—without cross-interference.

This modularity reduces the need for additional hardware, streamlining cabinet layouts in space-constrained facilities.
