II. Overview

1、This isolation safety barrier is suitable for thermocouple signal input in hazardous areas on site,After isolation,Convert into standard current or voltage signals and output them to the control system or other instruments in the safe zone.

2、It is an intelligent temperature transmission isolation safety barrier,can be passed throughPCThe machine and control software are programmed to set the input thermocouple type and range.

3、single channel,One way input,Output all the way. The isolation safety barrier is powered by an independent DC power supply-input-Isolation between outputs.

4、The temperature transmission isolation safety barrier can be connected to the unit combination instrument andDCSThePLCWaiting for the system to be used in conjunction,Widely used in various temperature detection and control systems for industrial production processes.

5、standard35mmDINRail card installation. Plug and unplug terminal block,Spring compression connection.
