ET-7215 - 7 Channel RTD Inputs
by ICP DAS
|
|
|
|
Modbus TCP Based Ethernet I/O Module with 2 Ethernet ports for daisy-chain networking and 7-channel RTD Inputs. Sensor types are Pt100, Pt1000, Ni120, Cu100, Cu1000. Communicable over Modbus TCP and Modbus UDP protocol, Supports operating temperatures of -25°C ~ +75°C (-13°F ~ 167°F) and has a din rail mount.

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