7B39 is a signal conditioning module produced by Analog Devices. It features a small size, low cost and a wide output voltage range. It can be applied to various industrial environments.
The 7B39 is a single‑channel signal‑conditioning module that isolates, filters, and converts 0‑10 V or 1‑5 V input signals to an isolated process current output of 0‑20 mA or 4‑20 mA. It is hot‑swappable, mix‑and‑matchable with other 7B series modules, and can be installed or removed without disrupting system power.
The handbook provides electrical specifications such as ±0.02 % non‑linearity, ±0.1 % accuracy, 1500 V rms continuous common‑mode isolation, and 110 dB common‑mode rejection. Mechanical data include dimensions of 1.663" × 2.11" × 0.563" and a weight of 60 g, as well as pin‑out diagrams and wiring details for integration into rack‑mount backplanes.
