FAQ

Q: Can this module operate outside Yokogawa systems? A: Yes. While optimized for CENTUM VP and ProSafe-RS, it supports any system accepting 4–20 mA analog input signals with DIN rail mounting.

Q: How does it reduce electrical noise? A: Each input channel is electrically isolated, minimizing interference and ground loop issues.

Q: Are communication protocols included by default? A: HART and Modbus/TCP options are available as add-on modules for network integration.

Q: How does NFAI143-S50 compare to NFAI143-S20? A: NFAI143-S50 provides 16 channels versus 8 in the S20, with higher isolation, making it more suitable for larger or noise-sensitive installations.
