Product Description

The FBM217 (Part Number P0916PW) is a high-density discrete input module for the Foxboro I/A Series and EcoStruxure DCS platforms. It provides 32 isolated contact sense channels, allowing the system to monitor "dry" contacts—such as limit switches, pushbuttons, and relay contacts—without requiring an external power source. The module internally provides the wetting current to detect contact closures.

Engineered with a rugged extruded aluminum housing, the FBM217 supports simplex and redundant configurations, ensuring critical interlocks and status signals remain monitored even if a module fails. Its high channel density minimizes cabinet footprint while maintaining robust electrical isolation.

Technical Specifications

Application

The FBM217 is commonly deployed in power generation, chemical processing, and water management. It monitors high volumes of discrete states such as motor starter auxiliary contacts, valve limit switches, and alarm panels, where high-speed detection and robust electrical isolation are critical.

Frequently Asked Questions

Q: Does this module require an external field power supply?
A: No, the FBM217 provides internal wetting current to sense the state of field contacts.

Q: Can this module be replaced while the system is running?
A: Yes, the FBM217 is hot-swappable. In a redundant configuration, the functional module continues processing all signals while the faulty one is replaced.
