PHC-22TD-1111
Overview
Isolated safety barrier at operating side: PHC-22TD-1111, dual input and dual output
with analog signal.
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 an external 20~35VDC power supply.
Terminal isolation between power supply, input and output.
