Product description

The Allen-Bradley 1756-IRT8I is a high-resolution analog input module for the ControlLogix platform. It features eight individually isolated channels that can be configured for Resistance Temperature Detector (RTD), Thermocouple, or millivolt signals. This module offers 24-bit resolution and supports various input ranges, including Ohms for RTDs and mV for thermocouples and millivolt sources. It requires a 36-pin Removable Terminal Block (RTB), such as the 1756-TBCH or 1756-TBS6H.

This module is designed for demanding industrial applications where accurate temperature and millivolt measurement is critical. It is widely used in process industries, power generation, and chemical processing for monitoring critical parameters. Its compatibility with various sensor types makes it versatile for diverse automation setups.
