HONEYWELL FC-IOTA-R24 51306505-175 Redundant IO Termination Assembly

Description

The HONEYWELL FC-IOTA-R24 51306505-175 Redundant IO Termination Assembly is an isolated input/output test accessory module designed for industrial control systems. It operates on a typical 24V DC working voltage, with input capabilities limited to monitoring dry contact (passive) signals, and output delivered via relay dry contact configurations, including normally open and normally closed options. The module supports a contact capacity of 2A @ 30V DC / 0.5A @ 250V AC, ensuring reliable signal transfer for connected field devices.

A key feature is its high-level electrical isolation of 1500Vrms between the logic and field sides, which protects sensitive control systems from voltage surges, ground potential differences, and other interference. It also integrates a manual test function, allowing maintenance personnel to test individual loops or devices without triggering system-wide alarms, simplifying troubleshooting and calibration.

Physically, the module uses DIN rail mounting for easy installation in control cabinets, and operates within a temperature range of -10 degrees Celsius to +55 degrees Celsius. It is fully compatible with Honeywell safety systems such as FGS and XLS1000, serving as a critical interface between control systems and field equipment including solenoid valves, alarms, and access control devices. It holds cULus and CE safety certifications, meeting global industrial safety standards.
