Introduction

The ET-7015 is specifically designed for long-distance RTD measurement. It features automatic compensation for three-wire RTD regardless of the length of wires and provides open-wire detection for RTD measurement. The ET-7015 offers 7 channels, each of which could be connected with different kinds of RTD (Pt100, Pt1000, Ni120, Cu100, Cu1000). Also, the ET-7015 is fully RoHS-compliant and has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.

Application

Building Automation, Factory Automation, Machine Automation, Remote Maintenance, Remote Diagnosis, and Testing Equipment.
