FBM202 | P0926EQ | Digital Input Module

Technical Specifications

Key Features and Advantages

The FBM202 P0926EQ delivers robust process monitoring with its 16-channel galvanic isolation, preventing ground loops in hazardous areas. Its solid-state design achieves 0.1% repeatability under voltage fluctuations, maintaining signal integrity in electrically noisy environments.

Intrinsic safety features: Certified for ATEX Zone 2 and Class I Div 2 operations, the module incorporates surge protection up to 4kV. The patented contact wetting technology ensures reliable detection of low-current field devices while consuming 40% less power than comparable models.

Diagnostic capabilities: Integrated channel-by-channel LED status indicators and module health reporting via Foxboro’s I/A Series protocol enable predictive maintenance. Hot-swappable design minimizes downtime during system expansions or replacements.

Application Areas

In oil & gas refineries, the FBM202 P0926EQ monitors critical safety interlocks for flare systems and emergency shutdown (ESD) valves. Its fast response time ensures compliance with SIL 2 safety requirements in process shutdown scenarios.

Chemical processing plants utilize this module for tank level switches and pump vibration monitoring. The wide temperature tolerance (-40°C to +70°C) supports outdoor installations in pipeline compression stations.

Power generation applications benefit from its surge-protected inputs for turbine bearing temperature switches and generator lockout relays, particularly in offshore wind farm substations.
