The HONEYWELL FC-IOTA-NR24 51306507-175 is a non-redundant I/O Termination Assembly (IOTA) designed for Honeywell's Safety Manager Safety Instrumented System (SIS). It provides the physical wiring interface between the safety I/O module and field devices, distributing 24 Vdc power to both the I/O module and connected field devices.

The FC-IOTA-NR24 is compatible with the FC-RUSIO-3224 Remote Universal Safe I/O Module and the FC-SAI-1620M Safe Analog Input Module. It features XS831 auxiliary terminals that enable 0–20 mA to 0–10 Vdc signal conversion for analog applications. The assembly supports direct wiring to field devices via terminal blocks and accommodates shielded cable connections for noise immunity

The FC-IOTA-NR24 51306507-175 HONEYWELL Non-redundant IO Termination Assembly may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The FC-IOTA-NR24 utilizes industrial-grade terminal connections that allow secure attachment of field wiring and provide clear identification for each channel. The design enables straightforward installation and replacement of associated I/O modules without disturbing field wiring connections, helping to reduce maintenance time and minimize operational interruptions.
As a non-redundant termination assembly, the FC-IOTA-NR24 is intended for applications where a single I/O path is sufficient and redundant channel architecture is not required. It is commonly deployed in emergency shutdown systems, burner management systems, fire and gas protection systems, turbine protection applications, and process safety installations.
  • Oil & Gas: Integrated into ESD, F&G detection, and automated offshore platform monitoring systems
  • Chemical/Petrochemical: Used for HIPPS and burner management with precision non-redundant termination in isolated loops
  • Power Generation: Deployed in turbine protection, cooling sub-systems, and generator safety monitoring loops
  • Marine/Heavy Industrial: Utilized for sub-system isolation and robust 24V DC field signal routing on vessels and facilities
  • Chemical/Pharmaceutical: Provides high-speed communication for recipe management, batch processing, and safety shutdowns
