FOXBORO FBM218 – Communication Redundant Output Interface Module | I/A Series DCS Platform
Engineering Background
The FOXBORO FBM218 is a field-proven output interface module engineered for the Foxboro I/A Series and Evo Distributed Control System (DCS) platform. Designed to meet the stringent demands of continuous process industries, the FBM218 provides redundant communication output capability, ensuring uninterrupted signal integrity in mission-critical control loops. This module is a cornerstone component in refinery, petrochemical, power generation, and advanced manufacturing automation architectures.
Product Positioning
The FBM218 is purpose-built for process engineers and control system integrators who require deterministic, fault-tolerant output performance. Its redundant communication architecture eliminates single points of failure at the field interface level, directly supporting SIL-rated and high-availability process control strategies. Konmask.com supplies the FBM218 as a verified, tested spare and replacement module with full traceability documentation.

- Long Service Life: Foxboro FBM modules are designed for 15+ year operational lifecycles in continuous process plants
System Architecture & Signal Flow
The FBM218 installs into a standard Foxboro FBM baseplate, which provides power, communication bus connectivity, and physical mounting. The module interfaces with the I/A Series Nodebus (or Evo DCS fieldbus backbone) via the baseplate backplane. Output signals are conditioned and transmitted to field devices (control valves, actuators, positioners) through the module’s terminal block connections. In redundant configurations, a secondary FBM218 module operates in standby mode, with automatic bumpless transfer upon primary module fault detection — ensuring zero-interruption output continuity.
Recommended pairing: Foxboro FBM218 is typically deployed alongside FCP270 / FCP280 Field Control Processors and CP60 / CP270 control processors within the I/A Series cabinet architecture.

Technical FAQ
Q: Is the FBM218 compatible with both I/A Series and Foxboro Evo DCS?
A: Yes. The FBM218 is backward-compatible with I/A Series v8.x and fully supported in Foxboro Evo DCS environments using the same FBM baseplate infrastructure.
Q: Can the FBM218 be replaced online without shutting down the process?
A: In a properly configured redundant FBM pair, the FBM218 supports hot-swap replacement. Process shutdown is not required when the redundant module is active and healthy.
Q: What is the difference between FBM218 and FBM217?
A: The FBM218 is the communication-redundant variant of the FBM21x output module family. The FBM217 is the non-redundant single-path version. For high-availability applications, FBM218 is the recommended specification.
Q: Do you provide a test report or functional verification certificate?
A: Yes. A functional test report and certificate of conformance are available upon request at time of order. Please specify this requirement in your RFQ.
Q: What is the lead time for FBM218?
A: Standard lead time is 3–7 business days for in-stock units. For bulk orders or specific firmware versions, please contact us for availability confirmation.
