Analog Devices 3B47-T-07 Isolated Linearized TC Input Module

Analog Devices' 3B47-T-07 Isolated Linearized Thermocouple Input Module is a plug-in signal conditioning module for 3B-series I/O backplanes that provides a single-channel, galvanically isolated thermocouple input with built-in linearization. It supports standard thermocouple types J, K, T, E, R, S, and B, and includes cold-junction compensation to deliver accurate temperature measurements across the thermocouple temperature range. The module also filters the input and converts the conditioned thermocouple voltage to a high-level analog output compatible with common analog I/O subsystems, enabling straightforward integration with industrial controllers and data acquisition systems. As a hot-swappable, mix-and-match component, the 3B47-T-07 can be swapped in or out without powering down the backplane, preserving uptime in automation environments. Typical applications include process temperature monitoring and control in manufacturing, chemical processing, and energy facilities where isolation from electrical noise and protection from transients are essential.
