DST-807 switch intelligent isolator

Classification:

Switching quantity input

The DST-807 switch quantity intelligent isolator converts the received switch quantity signal into an isolated switch quantity signal output to provide the required switch quantity control or alarm signal for the external system. It has an input state detection indication and can be used together with the unit combination instrument and DCS, PLC and other systems. This product requires independent power supply, input/output/power three isolation.

Keywords: Isolator
