Discrete and Analog Expansion I/O Features Chapter 2
The following table shows the default values of the High/Low Clamps (in the
order of low clamp value followed by the high clamp value) for the respective
type/range when they are first enabled. You can change these values (within their
full range) according to your application.
Specialty Module 2085-IRT4 Temperature Input Module
The 2085-IRT4 module lets you configure a sensor type for each of four input
channels that linearizes analog signal into a temperature value.
Sensor Type
The following Thermocouple and RTD sensor types are supported by the
2085-IRT4 expansion I/O module.
