PHD-11HD-21
Overview
Isolated safety barrier at detection side: PHD-11HD-21, analog input and output, single input and single output.
The isolated barrier can isolate and transmit the 4~20mA signal or DC 4~20 mA signal generated by the transmitter in the dangerous area to the safe area. When the transmitter is two-wire or three-wire system, the safety barrier provides power for the transmitter.
This product needs independent power supply.
This product supports HART signal and disconnection alarm.
