Relays

Relays are mechanisms that transmit electrical signals from switches, etc., to output components such as motors. These box-shaped devices mainly use electrical signals to control mechanical movements such as remotely opening and closing doors. Relays are widely used industrial equipment, ranging from large-scale equipment such as industrial robots and smaller equipment. Relays are generally classified into mechanical relays, whose contacts open and close mechanically, and SSR, which are semiconductor devices with no moving parts and are more suitable for applications that require frequent opening and closing. Terminal relays have 4 relays that enable independent 4-point controls, and are used for a more compact control panel layout. Multiple relays may also be combined according to application.
