Features:
- Operates reliably from -40°C to +70°C for harsh industrial environments.
- Includes a 15 A fuse with reverse polarity diode protection.
- Provides RJ-45 Ethernet and Weidmuller screw terminals for flexible wiring.
The FC-IOTA-NR24 51306507-175 is engineered to perform reliably in some of the most demanding industrial environments. Its wide operating temperature range of -40°C to +70°C ensures stable functionality in freezing cold storage facilities or sweltering factory floors. The storage temperature range extends to -85°C, providing a generous margin for transportation and standby conditions. Additionally, the module supports relative humidity from 10% to 95% non-condensing, making it suitable for humid environments without risk of internal corrosion or condensation-related failures.
The FC-IOTA-NR24 51306507-175 offers robust protection features that safeguard both the module and connected equipment. At its core is a 15 A Littelfuse blade fuse (5x19 mm, 32 V DC rating) that provides overcurrent protection against short circuits and overloads. The reverse polarity protection is implemented using a parallel diode that deliberately blows the fuse if the supply voltage is connected backwards, preventing damage to sensitive downstream electronics. The V+ pins (CN3) can deliver up to 1 A total current with a maximum voltage drop of less than 1.5 V at 0.7 A, and can withstand reverse voltages up to 36 V.
The FC-IOTA-NR24 51306507-175 provides versatile connectivity options to accommodate a wide range of field wiring requirements. It features two 16-position I/O connectors (CN1 and CN2) and a 4-position power connector (CN3), all using Weidmuller BLZ 5.08 series screw terminals. These terminals accept wire sizes from 0.50 to 2.50 mm² with a 7 mm strip length and require 0.5 Nm tightening torque for secure connections. The module also includes an RJ-45 Ethernet port for network communication.
The FC-IOTA-NR24 51306507-175 HONEYWELL Field Termination Assembly Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Emergency Shutdown Systems (ESD): Used in high-risk environments like oil refineries, offshore platforms, and chemical plants to execute failsafe shutdowns during dangerous process excursions.
- Burner Management Systems (BMS): Monitors and manages fuel, air, and flame control logic on industrial boilers, furnaces, and incinerators to prevent explosions.
- Fire & Gas (F&G) Systems: Connects toxic/flammable gas detectors, optical flame sensors, and acoustic horns to ensure safety logic handles hazards rapidly.
- Critical Process Control & Automation: Serves as a high-reliability universal junction for diverse field types (e.g., active/passive sensors, valves, solenoids) across heavy automation sectors.
- Host Module Firmware Dependency: The firmware resides in the processor of the plugged-in RUSIO/RUSLS active module.
- Firmware Upgrades via Safety Builder: When an active module requires a firmware flash or operating system update (e.g., during a Honeywell safety system migration to a newer release like R210+), the upgrade is pushed electronically over the safety network using Honeywell’s Safety Builder software tool.
- Safety Lock Considerations: Because this is part of a certified SIL 3 platform, firmware updates to the nested modules require specific access privileges, hardwired enabling keys, or system-maintenance mode states to override the functional safety interlocks.
- Channel Mapping: The assembly features 32 universal analog/digital channels (CN1 and CN2) along with dedicated V+ power distribution terminals (CN3) to supply active field devices (like 2-wire loops).
- Power and Grounding: 24V DC is fed through robust screw blocks onto the carrier rails. The baseplate features integrated reverse polarity diode protection and a 15A blade fuse to shield internal circuitry from field wiring surges.
- The Safety Builder Software Interface: Project engineers use Honeywell's specialized Safety Builder toolset to design the system topography. Within the software, the hardware tree is updated to include the FC-IOTA-NR24.
