Relay Basics The basics for all the relays are the same. Take a look at a 4 – pin relay shown below. There are two colours shown. The green colour represents the control circuit and the red colour represents the load circuit. A small control coil is connected onto the control circuit. ...
The design of an electromechanical relay uses a coil and current drive (or a voltage source) just as a solenoid does. However, the function of the relay is quite different. Despite the availability of alternatives for some applications such as the optical solid-state relay (SSR) and MEMS-bas...

The three-phase contactor coil requires modest current levels to function, and so the relay interposes between the PLC’s low-current output channel and the relatively higher-current demands of the contactor’s coil. Many load devices would consume far more current, and the ability to amplify ...

Industrial Control Basics: Part 2 – Overload Relays Electric motors are an integral component of industrial equipment, toys, vehicles, and electronic devices. They are designed to convert electrical energy into mechanical energy. These devices may be powered by AC or DC sources. Blowers, fans, ...
Contactor formats typically adhere to NEMA or IEC standards. The latter tend to be smaller for a given rating as well as less reliant on mass to dissipate heat from arcing — thanks to use of complementary contacts (and blowout coils) for electromagnetic arc quenching. Also integrated into the...
