PHD-12HD-211
Overview
Isolated safety barrier at detection side: PHD-12HD-211, analog input and output, single input and dual outputs.
The isolated barrier can isolate and transmit the 4~20mA signal or DC 4~20 mA signal generated by the transmitter in the hazardous 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.
