The FC-IOTA-NR24 is a non-redundant I/O termination assembly designed for industrial automation systems. It provides a reliable connection point for various I/O modules, including digital, analog, and safety types. As a termination assembly, it acts as the physical interface between field wiring and control system I/O modules.
This model is tailored for applications where redundancy is not critical, offering a cost-effective solution without backup paths. It supports robust industrial-grade performance, including wide temperature and humidity tolerance, and built-in protection against wiring errors such as reverse polarity.

Q1: What does “non-redundant” mean for this product?
A1: It means the assembly does not have backup or duplicate paths. If a failure occurs in the connected circuits or power, no automatic switching to a backup is possible.
Q2: Can this termination assembly work with redundant I/O modules?
A2: Yes, it can be used with redundant modules if wiring and system configuration allow, but the assembly itself does not provide redundancy.
Q3: What is the operating temperature range?
A3: -40 °C to +70 °C, suitable for most industrial environments.
Q4: Is there surge or signal conditioning protection built in?
A4: Only reverse polarity protection via built-in diodes is provided. Additional surge or signal conditioning must be handled externally.
Q5: How is the device mounted?
A5: It is installed inside control cabinets, requiring adequate space for its 44 cm length and secure mechanical fastening.
Q6: How should wiring be connected for power and ground?
A6: Power supply uses two M4 terminals, ground connections use eight M3.5 terminals, all requiring secure and corrosion-free connections.
Q7: Is the product certified for safety system use?
A7: It is designed for use within safety management systems, but certification for specific safety integrity levels (SIL) should be verified for your application.
Q8: What are the storage conditions?
A8: Stored between -40 °C and +85 °C with relative humidity up to 95%, non-condensing.
Q9: What is the weight and does it affect installation?
A9: Approximately 1.8 kg, requiring consideration for mounting support and cabinet space.
Q10: What is the main difference between FC-IOTA-NR24 and FC-IOTA-R24?
A10: FC-IOTA-R24 offers redundancy with backup paths; NR24 does not and is a simpler, cost-effective option.
