Product description

The Allen-Bradley 1746-INT4 is an Isolated Thermocouple/mV Analog Input Module designed for the SLC 500 platform. It features four individually isolated input channels, capable of handling thermocouple sensors (Types C, D, J, K, T, E, R, S, B, N) and mV signals ranging from ±50mV to ±100mV DC. This module provides 16-bit resolution and includes built-in cold-junction compensation for accurate temperature measurements.

This module is ideal for industrial temperature monitoring and control systems, ovens, furnaces, and thermal processing equipment. It is also well-suited for process automation upgrades and expansions within SLC 500 systems. Its robust design and isolation capabilities make it reliable in electrically noisy industrial environments.
