Solid State Relays have become an increasingly popular choice for automations, due to their many advantages over traditional mechanical relays. One such popular choice among automations is the OAA160STR, a mid-sized solid state relay that can be used in a wide range of applications. The OAA160STR is an ideal choice for applications requiring a high switching speed, as well as precise control and repeatabiity. This article will discuss the application field and working principle of the OAA160STR to better understand how it is used in various applications.

The OAA160STR is suitable for applications which require fast switching, such as controlling motors, lighting, and air handling. It is also suitable for applications where trigger voltages must be accurately and reliably generated and can be handled safely at temperatures ranging from -55°C to +125°C. The relay features a zero-voltage switching design which offers higher reliability, higher switching speeds and lower power requirements than standard mechanical relays.

The working principle of the OAA160STR is based on a semiconductor switching device called a thyristor, which is used to control the switching function of the relay. The thyristor is triggered by applying a voltage to the gate of the relay and the current passing through the relay is then controlled by this triggering action. When the thyristor is triggered, the current is allowed to flow through the relay and this action switches on the relay. When a negative voltage is applied to the relay gate, the thyristor is reset and the current will be off, automatically turning off the relay.

The OAA160STR is a self-extinguishing device that is capable of self-resetting, meaning that if the circuit experiences a fault, such as short circuit or over-voltage, the relay will energize and safely switch off by itself, without the need for an external reset. This feature ensures that the system remains secure at all times.

The OAA160STR has several advantages over conventional mechanical relays, such as: faster switching speeds, high reliability, low power consumption, and improved operational efficiency. Furthermore, the relay features an additional over-voltage protection circuit, which ensures that the system is protected against voltage surges. The OAA160STR also features a built-in step response protection circuit that is capable of limiting limiting the switching voltage to a safe value.

In conclusion, the OAA160STR is a perfect choice for a variety of applications, due to its fast switching, precise control, high reliability, and efficient operation. The OAA160STR provides a reliable and efficient solution for applications where precise control and repeatability is of utmost importance. With its high degree of reliability and wide range of application, the OAA160STR is an ideal choice for any automation system.
