Description
The ET-7015/PET-7015 is an ethernet based data acquisition module specifically designed for long-distance RTD measurement. It features automatic compensation for three-wire RTD so that it can provide accurate measurement, regardless of the length of wires. It also provides open wire detection for RTD measurement. ET-7015/PET-7015 offers 7 channels, each of which could be connected with different kinds of RTD (Pt100, Pt1000, Ni120, Cu100, Cu1000). Also, ET-7015/PET-7015 is fully RoHS-compliant and has 4 kV ESD protection as well as 2500 VDC intra-module isolation.
Configuration of the module is done via its integrated Web Server, while communication to a Data Logging / SCADA Package can be achieved using the ModbusTCP protocol.
The PET-7015 is a Power-over-Ethernet version, for use with a compatible Ethernet Switch. Please call us about this unit.
