The Foxboro FBM211 (P0914TN) is a high-density analog input module engineered for the I/A Series distributed control system. It provides sixteen independent 0 to 20 mA DC input channels, facilitating seamless integration between field instrumentation—such as flow, pressure, and level transmitters—and the system control processor. Engineered for demanding industrial environments, the module prioritizes signal integrity and process reliability through robust galvanic isolation and advanced digital filtering techniques.
Features
Sixteen high-resolution 0 to 20 mA DC analog input channels.
Integrated Sigma-Delta A/D conversion for superior noise rejection.
Supports redundant operation when paired on a compatible baseplate.
Galvanic isolation protects internal logic from field-side electrical interference.
Continuous self-diagnostic monitoring of A/D performance, memory, and communication health.
Redundant 2 Mbps HDLC fieldbus communication for high-availability data transfer.
Applications
This module is frequently deployed in mission-critical process industries, including oil and gas refining, chemical processing, and power generation. It is ideal for monitoring critical process variables where accuracy and high-speed data acquisition are required to maintain loop stability.

Installation Guidelines
Ensure the control system is powered down before inserting or removing the FBM211 module from the baseplate.
Verify that the baseplate is properly grounded to mitigate electromagnetic interference (EMI).
Use shielded twisted-pair cabling for field inputs to maintain signal integrity and reduce common-mode noise.
When configuring for redundancy, ensure both modules are correctly seated on the designated redundant baseplate slots to enable automatic failover.
Maintain adequate ventilation in the cabinet to ensure the module operates within its specified temperature range.
FAQ
Does the FBM211 support HART communication?
No, the FBM211 is a standard analog input module designed for 0 to 20 mA signals. For HART-enabled applications, please consult the Foxboro I/O catalog for compatible HART-specific FBM modules.
Is this module compatible with all I/A Series systems?
The FBM211 is specifically designed for the Series 200 I/O subsystem. Please confirm your baseplate compatibility and system software revision before installation.
