Solid State Relays – LAA120PLTR application field and working principle

Solid State Relays (SSRs) are electronic relays that have no moving parts. They are commonly used in situations where mechanical relays may prove too bulky or unreliable, for example in hazardous or sensitive environments. In particular, the LAA120PLTR SSR series is primarily used for motor control applications such as controlling motors, pumps or other high-power devices.

The LAA120PLTR series is a low-cost, low current draw solid state relay. It features an MOSFET transistor that has a threshold voltage of approximately 15V, making it ideal for microcontroller circuits. When the MOSFET gate is triggered, current is passed through the relay, switching on the device connected to it. The MOSFET used in the LAA120PLTR is capable of switching up to 75A, making it suitable for use with high-power motors and pumps.

The LAA120PLTR is perfect for applications such as controlling motors, pumps, lighting, HVAC systems, and other high-power devices. It can be used as a replacement for standard electromechanical relays, reducing the risk of sparking which can occur if the relay is switched too quickly. It also offers excellent EMC (electromagnetic compatibility) performance, reducing the risk of interference from other electronic devices. In addition, the LAA120PLTR is designed to be compatible with 5V – 24V logic signals, making it perfect for use in microcontrollers.

The LAA120PLTR can be triggered using a variety of control signals including relay contact closures, mechanical switches, 5V – 24V logic signals, and PLC controllers. The relay can be triggered using a DC voltage, such as 6V, allowing it to be used in applications where a constant control voltage is available. The relay is also capable of switching both AC and DC, making it suitable for use with a variety of AC and DC devices.

The LAA120PLTR is an excellent choice for controlling low-voltage applications such as pumps, motors, and other high-power devices. Its low-current draw combined with its high-power switching capabilities make it an ideal choice for industrial control applications. In addition, its compatibility with 5V – 24V logic signals make it an excellent choice for use in microcontrollers and PLCs.
