This design will interest technicians who work on pneumatically operated valves and other 4-20mA current loop controlled devices. Although 4-20mA signal injector/calibrators are available, this one is ...

Current-loop signals (vs. voltage signals) are widely used in industrial systems because they are much less subject to noise, and (within specified constraints) are relatively indifferent to line ...

High-End loop sensors provide PLC grade sensors to lower cost IoT site installations. SAN DIEGO, CA, UNITED STATES, May 23, 2023/EINPresswire.com/ -- Avimesa ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...

Instrument loop problems are frustrating at the best of times and can be really time consuming affairs to deal with. Most of the time these problems are related to isolation and ground faults.

Here’s a question for you: when your PCB has a ground plane layer, where do return signals flow? It seems like a trick question, but as [Kristof Mulier] explains, there’s more to return path routing ...
