7B21 is a single-channel signal conditioning module manufactured by Analog Devices. It can accept a +10 volt input signal, with a nonlinearity of +0.02% maximum and an accuracy of +0.1% maximum. All 7B21 series modules are mix-and-match and Hot Swappable.
The 7B21 is a single‑channel signal‑conditioning module that isolates, filters and conditions a +10 V input signal, providing a protected precision output of +10 V. It features a nonlinearity of +0.02 % max, accuracy of +0.1 % max, and 1500 V rms continuous common‑mode voltage isolation with 100 dB CMR.
The module operates from a nominal +24 VDC supply (acceptable range +14 VDC to +35 VDC), works over –40 °C to +85 °C, and is hot‑swappable in the 7B Series backplane. Physical dimensions are 1.663" × 2.11" × 0.563" and it weighs 60 g.
