AAI543-H61 S1_YOKOGAWA_PRODUCT_吉林易择科技技术发展有限公司

The Yokogawa AAI543-H61 S1 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.<br /> <br /> This model is a highly versatile module that accepts two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow). 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.
