Introduction
The I-7015 is a series of 6-channel RTD input modules that are used for measuring temperatures using RTD sensors and each channel can be connected to a different type of sensor. The I-7015P/M-7015P is specifically designed for long-distance RTD measurement, and features automatic compensation for three-wire RTD, meaning that accurate measurements can be obtained regardless of the length of the wires. The I-7015 series is fully RoHS-compliant and features 4 kV ESD protection as well as 3000 VDC intra-module isolation. The M-7015/M-7015P supports both the Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7015/I-7015P.
