7B47 is an isolated, linearized thermocouple input module from Analog Devices. It accepts input voltages from a J, K, T, E, R, S, B or N-type thermocouple, amplifies and filters them, and outputs a precision output of either +1 V to +5 V or 0 V to +10 V, linear with input temperature. All 7B47 series modules are mix-and-match and Hot Swappable.
The Analog Devices 7B47 is a single-channel signal conditioning module designed to interface, amplify, and filter input voltages from various types of thermocouples. It provides a precision isolated output of either +1 V to +5 V or 0 V to +10 V that is linear with the input temperature.
The module features galvanic transformer-based isolation rated for up to 1500 V rms continuous common mode voltage and includes high-level protection against field wiring transients. It operates within an industrial temperature range of -40°C to +85°C and is designed to be hot-swappable within the 7B Series backplane system.
