Analog Devices 3B46-00 Isolated Frequency Input

Analog Devices' 3B46-00 Isolated Frequency Input is a plug-in module in the 3B Series Signal Conditioning I/O Subsystem that accepts a galvanically isolated frequency signal and provides two simultaneous outputs for use with a data acquisition or control system: a voltage output 0 to 10 V (or ±10 V) and a current output 4–20 mA (or 0–20 mA). The 3B46-00 handles input frequencies up to 25 kHz and delivers input-to-output isolation up to 1,500 V rms, with the module encapsulated in the rugged 3B plug-in package. The 3B46-00 variant is factory-configured for a specified excitation voltage and frequency, matching typical sensor interfaces such as encoders or pulse generators in industrial automation. As part of the Analog Devices 3B Series, it is designed to interconnect real-world signals to a monitoring or control system with high isolation and two dedicated outputs.
