Ethernet I/O Module with 7-ch RTD Inputs



Model: ET-7015/PET-7015	Model: ET-7215/PET-7215


Built-in Web Server Web HMI Support for both Modbus TCP and Modbus UDP Protocols Communication Security 2-port Ethernet Switch for Daisy-Chain Topology Dual Watchdog Wide Operating Temperature Range: -25 ~ +75°C I/O Pair Connection Built-in I/O RTD Input: 7 Channels

The ET-7015/PET-7015/ET-7215/PET-7215 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/PET-7015/ET-7215/PET-7215 offers 7 channels, each of which could be connected with different kinds of RTD (Pt100, Pt1000, Ni120, Cu100, Cu1000). Also, The ET-7015/PET-7015/ET-7215/PET-7215 is fully RoHS-compliant and has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.
