1797-IRT8 "is a Flex Ex RTD thermocouple input module under the Allen Bradley brand of Rockwell Automation in the United States. Here are some of the main features and parameters of 1797-IRT8:

Input channel: It has 8 input channels and can be used to receive signal inputs from devices such as temperature sensors.

1797-IRT8 input type: Internal bus configurable input type, signal input range is 40-100 millivolts.

**Settling time * *: 8 milliseconds, which means the module's stable response time to the input signal is 8 milliseconds.

1797-IRT8 power consumption: The module's field side power consumption is 1.6 watts, and the power dissipation is also 1.6 watts. The heat dissipation per hour is 5.46 British thermal units (BTU/hour).

1797-IRT8 power supply requirement: The maximum power supply voltage is 9.5 volts DC.

Size and weight: Length is 3.7 inches, width is 2.95 inches, height is 1.8 inches, weight is 200 grams.

1797-IRT8 working environment: can only be used in indoor factory environments and must prevent water splashing. It can operate within a room temperature range of -4 to 158 degrees Fahrenheit (approximately -20 to 70 degrees Celsius), with a relative humidity requirement of 5% to 95% (non condensing).

Installation method: It has two options: DIN rail installation and panel installation, making it convenient to install in different positions.

The 1797-IRT8 product was discontinued on December 31, 2017. The substitute product is 1718/1719 Ex I/O. In some industrial automation control systems, the 1797-IRT8 module was widely used in temperature monitoring and control scenarios before its discontinuation.
