Honeywell FC-IOTA-R24 Redundant IO Termination Assembly
The FC-IOTA-R24 is a redundant I/O termination assembly engineered for Honeywell industrial safety and process control architectures. It provides reliable field wiring connections, power distribution, and communication interfaces for two redundant universal I/O modules, supporting high-availability loops in safety-critical applications.
System Compatibility and Architecture
This termination assembly is specifically designed to work with RUSIO-3224 and RUSLS-3224 I/O modules within the Honeywell Safety Manager platform. Dual connectors designated as CN1 and CN2 enable automatic failover capabilities. This ensures continuous operation and fault tolerance during module faults or routine maintenance in safety instrumented systems.
Power Distribution and Field Wiring
The unit supports an auxiliary supply voltage of 24 V DC within a range of 20.4 to 31.2 V DC, accommodating a maximum supply load of 10 A. It features four protected V+ power distribution terminals with a maximum total output of 1 A, simplifying the wiring of active analog field devices while offering parallel diode reverse polarity protection.
