Solid State Relays are automated switches that allow for efficient electrical control of low voltage circuits without any need for traditional electromechanical relays. Through the integration of semiconductor-based technologies, solid state relays can electrically isolate source load circuits safely.

The AQV414S series are solid state relays manufactured by Alitech Company. They utilize a relay or Triac interface to remotely switch an AC load circuit. The relay body in these Rdevices is made of a single piece of heat-resistant plastic and features a transmission frequency of no less than 100kHz, ensuring a mechanism with better anti-interference performance. Thanks to their sealed structure, the AQV414S relays are both robust and dust-proof, allowing them to be used in cases that involve environments with a high ambient temperature, and humid and dusty circumstances.

The AQV414S break-before-make function enables the relays to safely control the ON-OFF state of the load without producing any spark during the switching. With its small size and low energy consumption, the AQV414S-based system is convenient to assemble and maintain. Furthermore, the AQV414S series uses Zero Crossing technology, ensuring that the load will be turned on gradually without generating any impact switching current or EMC/EMI interference.

Moreover, many special functions can be realized with the AQV414S series. For example, they can be connected with a pulse generator and achieve a timing function or even the brake-before-make function. In addition, the AQV414S relays also support an input control signal of up to 250VAC. Depending on the specific needs of the application, the output control can be adjusted with an external potentiometer.

The AQV414S relay works with the principle of opto-isolation and voltage control. The input side consists of the opto-isolator that triggers the switching element, as well as an RC time circuit and snubber circuit combined with an electrolytic capacitor. On the output side, the AQV414S relay features a controlled load element and an R-C snubber. The opto-isolator used in the AQV414S relays makes it possible to realize a separation of the high voltage circuits from the low voltage circuits. This allows the source circuit to safely turn the load circuits ON or OFF without any risk of damages.

The AQV414S series are robust pieces of circuitry that can be widely used in areas such as industrial automation, facility monitoring and control, lighting access control systems, or driver interference protection systems. For applications involving a complex network of AC switching, the AQV414S shapes as a reliable device for providing control without sacrificing circuit safety.
