Introduction
The I-87015W is a 7-channel RTD input module that is used for measuring temperature using RTD. Each channel can be connected to different kinds of RTD sensor.
The I-87015PW is specifically designed for long-distance RTD measurement, and features automatic compensation for three-wire RTD so that it can measure accurately regardless of the length of the wires. The I-87015PW offers 7 channels, each of which can be connected to different kinds of RTD sensor.
Also, the I-87015W and I-87015PW are fully RoHS-compliant and features 4 kV ESD protection as well as 3000 VDC intra-module isolation.
