The document describes the features and characteristics of the 3B39 series modules, including interface, isolation, and filtering functions. The module is intended for high-accuracy industrial process control and monitoring applications, providing total galvanic isolation. The module circuitry can withstand 220V rms at the output screw-terminals.
The 3B39 is a single‑channel signal‑conditioning module that isolates and filters a 0 to +10 V or –10 V to +10 V input signal and delivers an isolated 4‑20 mA (or 0‑20 mA) process current output. It is designed for high‑accuracy process control and monitoring, offering +1500 V peak isolation and hot‑swappable operation.
The module fits into the 3B Series backplane, supports a variety of sensor inputs (thermocouples, RTDs, strain gauges, LVDTs, etc.), and provides two simultaneous high‑level analog outputs. Typical applications include microcomputer‑based data acquisition, programmable controllers, and analog recorders where temperature, pressure, flow, or other analog signals must be monitored.
