Solid State Relays

Solid state relays provide a reliable, efficient and economical way to switch high voltage loads. By utilizing the principles of semiconductor construction to control a high voltage load, the solid state relay (SSR) offers a much more robust and precise solution than traditional mechanical relays when it comes to applications requiring high resistance to vibration, temperature and moisture.

OSSRA0008A application field

The OSSRA0008A series of solid state relays are designed for AC control applications such as motor control, heater control, timer control, and lighting control. This series is used for loads up to 8A with an input voltage of 24-280 VAC/DC, and a switching power range of 0.6-2.5 W. Other features of the OSSRA0008A include a wide temperature range of -40°C to +85°C, an overload current of 5A, and a dielectric strength of 4Kv.

OSSRA0008A Working Principle

The OSSRA0008A solid state relay works by passing a current through a printed circuit board. This current is then measured by a pulse width modulated (PWM) signal which is triggered by a microcontroller. When the microcontroller senses a set voltage, the PWM signal will open a relay gate, allowing current to pass through the relay contact. This current flow triggers the solid state relay to switch the load to an on or off position, depending on the desired application.

The OSSRA0008A has a number of advantages when compared to traditional mechanical relays. First, since the relay gate is triggered by a PWM signal, the amount of time it takes for the solid state relay to open and close is much faster than a mechanical relay. This helps reduce the amount of time required by a load to be switched on and off, and helps reduce the amount of wasted energy due to a longer switch-on time.

Another advantage of using the OSSRA0008A is its level of protection against power surges, making it safer to use in applications that involve higher voltages. Finally, the OSSRA0008A also offers a low-noise operation, allowing it to be used in applications that require a quieter environment.

The OSSRA0008A is the perfect solution for any application that requires a reliable and robust switching solution. Its fast and efficient switching capabilities, surge protection and low-noise operation make it the ideal choice for any application.
