HV circuit breakers and protective relays in these settings protect large-scale electrical equipment, manage power flow and prevent damage from electrical disturbances.

Control applications often requirethat you set a relay latch in positionuntil you need it to change state.Latching relays accomplish that task.When you send them a pulse, they eitherremain in the ...

This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so that T1’s base voltage is 0.5V smaller than the emitter ...

Designers frequently use special circuits to reduce the power required to hold a relay in the latched position. Analog circuits such as the "brute force" resistor-capacitor solution ...

Prevent arcing and extra power loss in a relay circuit by timing its switching at zero-crossing with a high-voltage GreenPAK IC.

First, the corresponding relay circuit’s switch flips from “on” to “off,” recording that space as having a wall on that side. Then Theseus rotates 90° clockwise and moves forward.
