The 7B35 is a signal conditioner produced by Analog Devices. It is a single-channel signal conditioner that can be used for current input and outputs +1V to +5V or +2V to +10V. It has a 24VDC isolated loop power supply that can drive the transmitter. It is suitable for applications such as industrial signal isolation and industrial signal filtering.
The Analog Devices 7B35 is a single‑channel isolated process current input module that accepts two‑wire transmitters and provides a precision voltage output of either +1 V to +5 V or +2 V to +10 V. It features a 24 VDC isolated loop power supply, 1500 V rms transformer isolation and a 105 dB common‑mode rejection, making it suitable for noisy process‑control environments.
The module is hot‑swappable, fits a 19‑inch rack‑compatible backplane, and offers specifications such as an input range of 4 mA–20 mA, output resistance under 12 Ω, operating temperature from –40 °C to +85 °C, and a weight of 60 g. Mechanical dimensions are 1.663 in × 2.11 in × 0.563 in.
