HDH-20 series AC voltage transmitter is used to isolate and convert AC voltage signals into standard analog signals. It is used for DCS to centrally monitor motors, pumps or heat networks, and monitor power supply lin
es and their currents.
Reliable isolation of input, output and power three ports
Selection example:
HDH-20-XXX
Eg: HDH-20-1B1 one in and one out, input 0-300V, output 4-20mA, 24VDC power supply
