Analog Devices 3B34-CUSTOM MODULE ISOL WIRE RTD-IN LIN RTD Input Module

Analog Devices 3B34-CUSTOM is an isolated RTD input signal-conditioning module in the 3B Series, designed for plug‑in on a 19‑inch backplane system. It accepts 2-, 3-, or 4‑wire RTD sensors and provides sensor excitation with lead compensation and a linearized output that correlates RTD temperature with the signal. The module provides two simultaneous outputs: a voltage output (0 to 10 V or ±10 V) and a current output (4–20 mA or 0–20 mA), enabling direct connection to high‑level analog I/O. Between input and output, the isolation rating reaches up to ±1500 V peak, in line with the 3B Series isolation approach, and the product is listed as Obsolete.
