FOXBORO FBM237
Product Introduction
Driving final control elements with zero-bump redundancy requires an output module that eliminates single points of failure at the channel level. The delivers 8 channels of isolated 0-20mA outputs with built-in redundant-ready architecture, ensuring seamless failover during hardware or communication faults.
Designed for critical process control, this module supports the AOUTR redundant analog output function block for automatic switching between primary and backup channels. The is electrically compatible with HART signals, allowing you to maintain smart device communication while benefiting from redundant analog output, making it essential for safety-critical valves and actuators in chemical, oil and gas, and power generation applications.
Key Selling Points & Differentiators
- Redundant-Ready Architecture: Supports the AOUTR function block for automatic failover between redundant output channels, ensuring continuous control signal delivery during module or communication failures.
- 8-Channel High-Density Output: Processes 8 independent 0-20mA outputs in a single module, maximizing I/O density while maintaining full channel-to-channel isolation.
- HART Electrical Compatibility: Electrically compatible with HART protocol signals, enabling bidirectional communication with smart positioners and actuators without additional hardware.
- Verified Functionality: Every undergoes a 24-hour live load test on a dedicated I/A Series test rack before shipping, complete with a signed test report.
- Not Recommended For: Do not use this module for voltage outputs or discrete switching; it is strictly a 0-20mA redundant analog output card. Use FBM242 for discrete outputs or FBM218 for HART-specific redundant outputs.
- Stock Availability: Current inventory is factory-sealed new surplus with traceable lot numbers; typically ships within 48 hours of order confirmation.
- Warranty Backed: Includes a 1-year functional warranty covering manufacturing defects and DOA conditions, with no restocking fees for verified failures.

FAQ
Yes. All units in stock have passed our 24-hour live bench test and include a signed test report. We ship same-day for orders placed before 2 PM EST, so you’ll have tracking before end of day.
The is designed for standard I/A Series FBM baseplates, but verify your baseplate revision and node processor firmware first. Redundant output modules often require specific firmware levels to properly initialize the AOUTR function block. Send us your baseplate and node part numbers, and we’ll confirm compatibility within 30 minutes.
How does the redundant switching work?
The works with the AOUTR redundant analog output function block in the I/A Series controller. When configured, the controller monitors both primary and backup channels; if the primary fails, the backup automatically assumes the output current without bumping the final control element.
Do I need to reconfigure the module after installation?
No. The retains its configuration in the I/A Series node processor. Simply plug it into the same slot, and the system will recognize it. However, always verify redundancy settings, fail-safe modes, and output scaling in your DCS configuration tool after replacement.
What if one channel fails?
The redundant architecture ensures that the backup channel assumes the output for the failed channel while reporting the fault. You can hot-swap the module without removing field wiring or interrupting process control.
Can this module handle HART transmitters?
Yes. The is electrically compatible with standard HART signals, allowing you to maintain smart device communication while benefiting from redundant analog output.
Is this a refurbished or new surplus unit?
This is New Original (New Surplus) – factory sealed, never installed, with full traceability to the original manufacturing lot. It is not refurbished, repaired, or pulled from a decommissioned system. We provide the original manufacturer’s lot code upon request for your quality records.

Technical Risk Avoidance
- Redundancy Configuration Error: Risk: Failover not working. Prevention: Verify AOUTR function block is correctly configured in the controller. Field Note: We’ve seen FBM237s fail to switch because the AOUTR block wasn’t linked to the output channels. Always verify the function block configuration.
- Baseplate Seating: Risk: Intermittent output or redundancy failure. Prevention: Ensure the module is fully seated and locked onto the baseplate. Field Note: A partially seated FBM caused random output dropouts and failed redundancy tests. Push firmly until the latch clicks.
- Fail-Safe Mode Mismatch: Risk: Unsafe process state during failure. Prevention: Verify fail-safe mode (hold vs. 0mA fallback) matches your process safety requirements. Field Note: A valve held in last position during a controller failure caused an overpressure event. Configure fail-safe correctly.
- HART Communication Issues: Risk: Smart device not responding. Prevention: Verify loop resistance is 250Ω–600Ω for HART communication. Field Note: We’ve seen HART polling fail because the loop was only 180Ω. A 2 resistor fixed a 3,000 “bad card” diagnosis.
- ESD Damage: Risk: Silent output drift or channel failure. Prevention: Use grounded wrist strap and anti-static mat during handling. Field Note: We’ve tested modules that passed power-on but had drifted outputs after 48 hours due to ESD. Handle with care.
