Technical Description
The NFAR181-S00/R8S0 is a high-precision analog input module for Yokogawa CENTUM VP and ProSafe-RS control systems, optimized for temperature measurement. It features 8 isolated RTD input channels, capable of interfacing directly with Pt100 and other industrial RTDs. Advanced signal conditioning and linearization circuitry converts resistance readings into accurate process values. Housed in a standard FIO (Field Interface Option) form factor, it maximizes I/O density within marshalling cabinets. The S00 hardware revision and R8S0 terminal interface ensure compatibility with standard RTD wiring.

Operational Application
The NFAR181-S00/R8S0 is ideal for temperature-critical processes in refineries, chemical plants, and power generation facilities. It delivers high-resolution data for loop control, safety interlocks, and equipment health monitoring. Features like internal cold-junction compensation and linearization remove the need for external converters, simplifying cabinet wiring and lowering total cost of ownership.
Frequently Asked Questions
Does the module support 3-wire RTD connections?
Yes. It accommodates standard 3-wire RTD configurations to compensate for lead-wire resistance in extended cable runs.
Can the module be replaced while the system is operating?
Yes. The FIO module series supports hot-swapping, allowing maintenance without interrupting the controller node or other I/O loops.
Does the module detect sensor burn-out?
Yes. It provides diagnostics for open-circuits (burn-out) and short-circuits, immediately alerting the CENTUM operator HMI.
