It features fast response, low temperature drift and high accuracy. This product requires an independent power supply, with three-terminal isolation of input, output and power supply.<\/p>\n<p><strong>Note:<\/strong>Three-terminal isolation of input, output and power supply. 24V DC independent power supply; the input side provides 1 channel of isolated power supply for 2-wire\/3-wire transmitters (open-circuit voltage \u226426V, output voltage at 20mA \u226522V) and detects the transmitter current signal; the output side provides 0\/4\uff5e20mA (RL\u2264550\u03a9) to the DCS\/PLC AI channel; bidirectional HART digital signal transmission, with pass-through on both input and output sides.
