AQV216SZ solid state relays are multichannel or single channel devices designed to switch voltages in low or medium power applications. AQV216SZ relays have a variety of features, including zero-crosstime, isolation and protection of the load from the main power supply. Moreover, they are designed to be more reliable and have a longer life span than traditional relays. AQV216SZ solid state relays are commonly used in the automotive, industrial, commercial and building automation industries.

The AQV216SZ is a single phase solid state relay consisting of a two-input module connected to a control power supply, and a two-output module. The control power supply varies between 8-20VDC for the active and 18-30VDC for the passive state of the relay. The output module switch allows it to be connected with the load, and is the part that matches the set voltage and current ratings of the load to be switched. In the active state, the AQV216SZ solid state relay is able to switch voltages up to 10A load and 60Vdc.

The AQV216SZ solid state relays are a constant pursuit of optimized switching technology, relying on bipolar transistors, SCRs and Opto-couplers (LED) for main components. In order to meet the requirements of various applications, the AQV216SZ has different switching speeds, zero-cross-time, and anti-interference capabilities.

When using the AQV216SZ solid state relay, one must consider the parameter settings. The parameter settings for AQV216SZ relays depend on the associated circuit and load. The parameters can be adjusted for the best performance, and the correct setting should be selected to ensure a stable operation of the device. If the parameters are incorrectly set, the device may malfunction or operate abnormally.

The working principle of AQV216SZ solid state relays is based on the self-trigger of triac. When the voltage applied on the input terminal is larger than a certain level, the voltage difference between two ends of the triac will set it into conduction. The AC load will be switched on until the current is nearly zero. The AQV216SZ relay uses opto-coupler receivers (LED) connected in series with the triac. The LED helps to improve the stability and accuracy of switching.

Thus, AQV216SZ solid state relays are ideal for applications in which fast and accurate switching is required, such as in engine control, industrial machines, lighting control, and home automation systems. The AQV216SZ relay is usually used to switch load voltage between 0-60VDC; therefore, it is suitable for applications such as automotive engine controllers, thermal controllers, industrial process controllers, lighting control, switching power converters, emergency lighting controls, and home automation systems.
