Overview

The Honeywell FC-IOTA-R24 Redundant IO Termination Assembly is a key component in Honeywell’s safety and process control architecture. Designed for use with redundant I/O modules such as the RUSIO-3224 and RUSLS-3224, it offers 32 universal I/O channel connections through dual connectors (CN1 and CN2), enabling automatic failover in case of module failure. This redundancy ensures continuous operation in SIL 3-certified safety instrumented systems.

The FC-IOTA-R24 includes four identical V+ power distribution terminals, supporting active analog input devices and simplifying field wiring. With its compact footprint and rugged build, it is suitable for installation in control cabinets across various industries like oil & gas, chemical processing, and power generation.

Technical Data

Typical Applications

• Safety Instrumented Systems (SIS): Ensures reliable I/O termination for redundant safety logic in chemical and petrochemical plants.

• Process Control Networks: Interfaces with universal I/O modules for analog and digital signal routing in distributed control systems.

• Power Generation Facilities: Supports turbine and boiler control systems requiring high availability and fault tolerance.

• Oil & Gas Installations: Used in upstream and midstream automation systems for real-time monitoring and control.

• SCADA and RTU Panels: Provides robust I/O connectivity in remote terminal units and supervisory control systems.

For example, the FC-IOTA-R24 is deployed in dual-channel safety loops to ensure continuous operation during maintenance or fault conditions. Its modular design also simplifies system expansion and reduces wiring complexity.
