The Yokogawa NFDV161-P00 is a high-density digital input module designed for the FCN / FCN-RTU / STARDOM distributed control system, enabling reliable acquisition of ON/OFF signals from field devices such as switches, sensors, relays, and interlocks.
Compared with the NFDV151 series, the NFDV161 offers expanded input capacity (up to 64 channels), making it ideal for large-scale automation systems that require dense signal collection, reduced cabinet space, and simplified wiring architecture. It is widely used in oil & gas, petrochemical, power generation, and industrial SCADA systems.
