Used in tandem with a current source, Zensol's SIM-CB is a circuit breaker simulator that tests any type of protection relay (such as CEPA used by the Hydro-Québec electric facility). April 21, 2009 ...

October 21, 2011. Teseq Inc. has introduced the NSG 438A, a new ESD simulator that includes an integrated discharge relay circuit to dissipate residual voltage in conventional ESD testing and ...

Switching applications involving controlling devices or appliances using digital-I/O lines through a relay often need to indicate the change of state of the I/O line and, hence, the connected device.

[SaltyPuglord] needed a solid state relay for a project. We’d have just bought one, but he decided to design his own in LTSpice. Along the way he made the video below, which is pretty informative and ...
