The 2 channel solid state relay (SSR) is free of moving parts thanks to solid state technology. As a result, this relay is faster and more reliable than a traditional magnetic relay. The specific design of these relays allows for a load of 100-240V AC with a current rating of 2A. In addition, each output is protected from overload by a pico fuse. The use of a low-level trigger makes this relay compatible with all microcontrollers with at least a 3.3V logic level. Technical features: Size 55 * 33 * 25mm Weight 21.5 g Supply voltage 5V Trigger mode Low level trigger Static voltage 0mA Load current 2A Maximum operating current 48.8mA Module lifetime 10 million times Practical high performance module: Compared with the traditional mechanical relay, the solid state relay (SSR) has many advantages: It has a longer life, much higher turn-on and turn-off speed, and is noiseless. High quality: Go for high quality in your relays and use the solid state relays from AZ-Delivery.
