the total circuit power is reduced to 50%. (good savings!) For this, make the series resistance equal to the coil resistance. Which factor should I use—67% or 50%? This is a function of relay pickup ...

The circuit shown in Figure 1 takes an electromechanical approach to implementing a toggle function, replacing the Schmitt trigger IC in Olenyik’s design with a relay. Figure 1 A momentary-contact ...

Their main function is to assist in starting the motor ... The start winding is still in the back-EMF circuit, keeping the relay’s coil energized while the motor is running at full speed. The contacts ...

Examples of these functions commonly include power to ... should there be a fault on the wiring supplying power to the relay. A circuit fault or any other loss of power to operate the life safety ...

Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.

Electroswitch control switch relays combine the function of a control switch with a remote-controlled solenoid allowing one device to do both the manual and supervisory control function in the control ...

Other similar form-factor ISO relay variations may have only NO or NC circuits, but because of the terminals' universal numbering scheme, you can always figure out their function and how to wire them.

It performs the same function as a current relay or potential relay but in a much different manner. A PTC relay uses a positive temperature coefficient thermistor to remove the start winding and/or ...

This relay can help small and medium machine builders reduce cost and save space. The PSR-MXF accepts up to three dual-channel safety sensors: two local, independent sensor circuits, as well as an ...
