The Yokogawa NFDV161-P00 S2 is a 64-channel digital input module designed for the FCN / FCN-RTU / STARDOM distributed control system, providing highly reliable ON/OFF signal acquisition from field devices such as switches, sensors, interlocks, and relay contacts.
The S2 variant represents an enhanced system configuration level, typically used in projects requiring higher stability, stricter environmental adaptation, and improved system-level compatibility. It is especially suitable for large-scale industrial automation systems where maximum I/O density and long-term operational reliability are critical.
