Product Overview
The FOXBORO FBM216B P0927AJ is a high-density digital output module designed for safety-critical applications within the FOXBORO I/A Series® DCS platform. This rugged module provides 32 points of isolated digital control with redundant switching paths (1oo2 architecture) for applications demanding SIL 3 safety integrity. The FOXBORO FBM216B P0927AJ features patented fail-safe circuitry that forces outputs to predetermined states upon detection of faults or power loss, ensuring failsafe shutdown in processes like emergency depressurization or fire protection systems. With arc-flash suppression technology and gold-plated relays rated for 2A @ 24V DC, it eliminates secondary failures during inductive load switching. Housed in an IP66-rated enclosure with chemical-resistant coating, the module withstands washdowns in pharmaceutical/food processing plants and sustains 50G operational shock per IEC 60068-2-27.

Key Features and Advantages:
Functional Safety Assurance:
Dual ARM Cortex-R52 processors execute synchronized self-tests every 2 ms, detecting >99% dangerous failures (PFH<1E-09). Output state validation uses redundant voltage/current sensing paths.
Explosion Prevention:
Integrated R-C snubber networks suppress 500V spikes from solenoid valves. Creepage/clearance >8mm prevents arcing in Group IIC hazardous areas (ATEX certified).
FBM216B
Predictive Maintenance:
Embedded health metrics track relay cycle count and contact erosion. Load impedance measurement (±5%) detects broken wires before safety function impairment.
Application Domains
The FBM216B P0927AJ dominates safety shutdown systems:
- Oil & Gas: ESD valve control in flare stacks with SIL 3 Fire & Gas loops
- Chemical Plants: Emergency quench system activation for runaway reactions
