Analog Devices 3B41-Custom Isolated Wideband V Input

Analog Devices 3B41-Custom Isolated Wideband V Input is a single‑channel module in the 3B Series Signal Conditioning Subsystem that conditions real‑world voltage signals for data acquisition and control systems. It provides galvanic isolation between the field signal and the system electronics up to ±1500 V peak, and the input path offers wideband performance up to 10 kHz (-3 dB) with an integrated two‑pole Butterworth filter; isolation is accomplished by transformer coupling with a proprietary modulation technique. The “Custom” designation indicates factory‑configured input/output ranges are available (3B41‑CUSTOM) to suit specific measurement needs, while the module also delivers simultaneous precision voltage and current outputs for direct interfacing to ADCs or instrumentation. Power is drawn from ±15 V DC and a +24 V DC supply, per the 3B41 family’s standard power scheme. The device is designed to amplify, filter, and protect voltage inputs, with field‑side connections and isolation that supports use in instrumentation, process control, data acquisition, and test setups requiring high‑voltage isolation and compact form factor within the Analog Devices 3B system.
