Problem Here’s a scenario that may be familiar: the current of a high voltage load needs to be monitored with a current sensor, and the current sensor needs an integrated relay with 10A rated contacts. It seems easy, however when working with high voltage, some special equipment (and maybe even a licensed professional) is required. […] Read More
Versatility… We all like it. Our most popular relay, model RIBU1C, is versatile because it can be controlled by any voltage between 10V and 30V AC or DC as well as 120V. It’s even more versatile because it has a set of SPDT dry contact outputs. Those outputs could be used for high voltage, low […] Read More
