In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

Relays continue to be useful and popular, but in low-power, battery operated applications they tend to be power wasters. The following relay economy circuits reduce coil power significantly by simply ...

If you understand the relay function, email sending limits and costs become a thing of the past. The SMTP relay function will help your business move beyond the basic features of email and provide ...

ATS is a piece of hardware that automatically shifts the electrical load from primary power supply to a backup or standby ...

Electroswitch control switch relays (CSR) 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 ...

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 ...

Vulnerabilities in networked devices programmed to instantaneously trip power grid substation circuit breakers could be the ...

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

Movement is a complex process governed by a network of neuronal circuits spread across multiple regions of the nervous system ...

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