Overview

The Foxboro FBM214B RH927AH module is a high-performance HART analog input interface designed for advanced industrial automation. It supports eight individually isolated 4–20 mA input channels, enabling seamless integration of both conventional transmitters and HART-enabled field devices.

By providing accurate process data acquisition alongside remote configuration and device diagnostics, the FBM214B enhances operational intelligence and reduces maintenance downtime. Its rugged build and DIN-rail mounting allow reliable installation even in compact or harsh industrial environments.

Technical Data

Application

This module is widely used in process industries requiring precision and intelligent diagnostics:

• Oil & gas — monitoring pressure, flow, and level transmitters

• Chemical plants — corrosion-resistant field I/O integration

• Power generation — turbine and balance-of-plant instrumentation

• Distributed I/O systems — long-distance runs with strong noise immunity

With independent channel isolation and HART support, it simplifies system design while maximizing uptime and data visibility.
