Overview
H serie backplane mounting isolated safety barriers at operating side: PHC-11HD-11, input and output with analog, single input and single output.
The safety barrier can transmit the 4~20mA signal from safe area to the dangerous area, to drive the valve positioner, electric/gas converters and other actuators to work.
This product needs independent power supply.
Terminal isolation between power supply, input and output.
