  • Increasing Load Capacity in PhotoMOS® Relays
    January 21, 2015
    PhotoMOS Relays inherently have a limited DC load, however, by changing the output terminal connections, 6-Pin DIP and SOP type PhotoMOS Relays can withstand a higher load capacity.

    Using PhotoMOS Relays For More Than Test And Measurement PhotoMOS Relays are not only for test and measurement applications. These solid state Relays can also switch and protect small motors, power supplies, and control devices with load currents up to 6 amps. To do this, PhotoMOS Relays combine high switching speed with low control current and reliable overcurrent protection.

    PhotoMOS Solid State Relays In an earlier blog post, we described the principle of operation of a PhotoMOS solid state Relay. Now we'll look at some considerations when designing the circuit around the PhotoMOS.

    An Introduction To Relays  A Relay is an electrical component whose output is controlled in an open or closed position by applying or removing drive voltage from an electrically isolated circuit. For many years, electromechanical Relays were the only choice to perform such a function. During the last two decades, however, new technologies have emerged enabling semiconductors to switch output circuits with an electrical control signal via electronic, magnetic, optical or other means that require no mechanical movement.

    Modern applications use complex controls to enhance safety, implement convenient features, and save energy. Control units use switches to control the sensors and actuators in a system. Since most applications are powered from the AC mains network, several AC voltage loads have to be controlled (For example, heaters, lamps, motors, fans or valves).
