The Yokogawa NFAI143-H50 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Analog Input Isolator and Converter.
This model is a versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow transmitters). It provides electrical isolation between the input, output, and power supply circuits for each channel, and converts each input into a corresponding 4 to 20 mA DC output signal.
