The Yokogawa NFSB100-S00 is a Signal Conditioner from the NFS series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Isolator and Converter.
Its primary function is to accept two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow), provide electrical isolation between the input, output, and power supply circuits, and convert each input into a corresponding 4 to 20 mA DC output signal.
