Product Description

The FBM214B (P0927AH) is an 8-channel HART-enabled analog input module for the Foxboro I/A Series DCS. It processes 4–20 mA signals while simultaneously capturing high-speed digital data from smart field instruments, such as pressure, temperature, and flow transmitters. This enables the DCS to monitor primary process variables alongside secondary and tertiary HART diagnostics.

Designed for modern smart plants, the FBM214B functions as a transparent HART gateway, supporting remote device configuration, proactive maintenance, and asset management while maintaining galvanic isolation between field circuits and the system backplane. This ensures system integrity even under field-side electrical disturbances.

• Smart level sensor integration in hazardous chemical storage tanks

Frequently Asked Questions

How does the FBM214B differ from the standard FBM214?
The FBM214B (P0927AH) is optimized for high-speed HART data throughput, handling multiple HART variables (PV, SV, TV, QV) more efficiently than standard FBM214 modules, making it ideal for advanced asset management applications.

Is this module compatible with both 2-wire and 4-wire transmitters?
Yes. It can provide loop power to 2-wire transmitters or accept externally powered 4-wire inputs, depending on the field wiring and terminal assembly configuration.
