features and benefits
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.
