Foxboro FBM214B P0922VT HART Input Module | Eight Isolated Channels

Product Description

The Foxboro FBM214B P0922VT is a HART communication input module designed for the Foxboro Evo and I/A Series DCS. It features eight individually isolated 4–20 mA analog input channels with integrated HART capability, allowing simultaneous analog measurement and digital communication from field transmitters.

This module acts as a HART field device host, supporting universal, common practice, and device-specific commands through pass-through functionality. Each channel accommodates either standard 4–20 mA devices or HART-enabled transmitters, enabling incremental upgrades of legacy loops without requiring system changes.

With practical HART throughput of up to two digital messages per second per device, the FBM214B balances diagnostic access with stable analog process scanning. Its robust design and isolated channels ensure accurate measurements and reduced interference, making it suitable for industrial automation in power generation, petrochemical, water treatment, and manufacturing environments.
