The Allen-Bradley 1794-IRT8 is an 8-channel FLEX I/O analog input module designed for high-accuracy temperature and low-level signal measurement in distributed industrial automation systems. It supports thermocouple, RTD (2-, 3-, and 4-wire), and millivolt inputs within a single compact module, providing flexible sensor integration while reducing cabinet space and wiring complexity. As part of the FLEX I/O platform, it integrates seamlessly with programmable controllers through FLEX I/O adapters and terminal base units, making it suitable for process monitoring, manufacturing, and industrial control applications.
Acquires temperature and low-level analog signals from thermocouples, RTDs, and millivolt sources.
Supports up to 8 input channels divided into two groups of four.
Converts analog signals with 14-bit resolution for accurate measurement.
Integrates with FLEX I/O distributed architectures through FLEX I/O adapters.
Supports firmware-based configuration, eliminating the need for hardware switches or jumpers.
Provides continuous monitoring of process temperature and sensor status for industrial automation systems.
