The 7B47 series modules are Analog Devices' isolated, linearized thermocouple input modules that interface, amplify, and filter input voltages from a J, K, T, E, R, S, B or N-type thermocouple, providing a precision output of either +1 V to +5 V or 0 V to +10 V, linear with input temperature.
The 7B47 is a single‑channel signal‑conditioning module that interfaces, amplifies and filters input voltages from J, K, T, E, R, S, B or N‑type thermocouples. It provides an isolated, precision output of either +1 V to +5 V or 0 V to +10 V, linear with temperature, and includes built‑in cold‑junction compensation.
The module is hot‑swappable, accepts a +14 VDC to +35 VDC supply, and offers up to 1500 V rms continuous common‑mode isolation with 120 V rms input protection. Mechanical dimensions are 42.24 mm × 53.6 mm × 14.3 mm, weight 60 g, and it operates from –40 °C to +85 °C.
