The Yokogawa AAI543-H53 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Analog Isolator and Converter.
This model is a highly versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters. It provides electrical isolation between the input, output, and power supply circuits for each channel, and converts each input into a corresponding 1 to 5 V DC output signal.
