Product Introduction
The Allen-Bradley 1794-IRT8XT Flex I/O-XT Thermocouple RTD Input Module is an extended temperature analog input module designed for precise temperature and low-level signal measurement in demanding industrial environments. As part of the FLEX I/O-XT series, it is engineered to perform reliably in harsh and corrosive conditions, making it suitable for applications where environmental resilience is essential.
This module provides 8 non-isolated input channels and supports multiple signal types, including thermocouples, RTDs, millivolt signals, and strain gauges. With 14-bit resolution, it delivers accurate and stable data acquisition, enabling precise monitoring of temperature and process variables.
The conformal coating enhances protection against moisture, dust, and corrosive elements, extending the module’s operational lifespan. Combined with its wide operating temperature range of -20°C to +70°C, the 1794-IRT8XT is well-suited for distributed control systems deployed in extreme industrial environments.
