Yokogawa NFTR8S-10 RTD Input Module

Overview

The Yokogawa NFTR8S‑10 is a high-precision 8-channel RTD input module designed for the FCN (Field Control Node) autonomous controller platform. It delivers stable and accurate temperature measurements using industrial-grade RTDs such as Pt100 and JPt100. Each input channel is fully isolated to ensure signal integrity in electrically noisy and harsh industrial environments. This module is ideal for process industries requiring precise temperature monitoring and control.

FAQ

Q: Can this module support 2-wire RTDs?
A: The NFTR8S‑10 is optimized for 3-wire RTD inputs; 2-wire configuration may reduce measurement accuracy.

Q: How does it differ from the NFTR4S module?
A: NFTR4S offers 4 channels versus 8 on NFTR8S‑10. Both provide high isolation and accuracy, but NFTR8S‑10 is suited for higher channel density applications.

Q: Is the module hot-swappable?
A: The NFTR8S‑10 is designed for plug-in installation but should be powered down during replacement to ensure system safety.
