PHC-11TD-11/ PHC-12TD-111
Overview
The analog output isolated safety barrier can realize the isolated transmission of 4~20mA signals from the instruments in the safe area to the dangerous area, drive the valve positioner, electric/pneumatic converter and other equipment on site, and support the bidirectional transmission of HART digital signals. This product needs independent power supply, and the power supply, input and output are isolated.
