The 4 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. Features: Small and practical Size: 57 x 55 x 23mm Net weight: 36.6 g Easily applicable in many Arduino and Raspberry Pi projects The screw terminals are well labeled. Technical features: Dimension 57 x 55 x 23mm/td> Weight 36.6 g Supply voltage 5V Trigger Low level trigger Switch voltage 100-240 V AC Switching load current 2A Module life 10 million times Practical high performance module: Compared to the traditional mechanical relay, the solid state relay (SSR) has many advantages: It has a longer life, a 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. https://elecena.pl/product/22111931/4-channel-solid-state-relay-5v-dc-low-level-trigger-power-switch-compatible-with-arduino-and-raspberry-pi 2022-11-20 https://elecena.pl/product/22111931/4-channel-solid-state-relay-5v-dc-low-level-trigger-power-switch-compatible-with-arduino-and-raspberry-pi 2023-07-25 https://elecena.pl/product/22111931/4-channel-solid-state-relay-5v-dc-low-level-trigger-power-switch-compatible-with-arduino-and-raspberry-pi 2024-02-14 https://elecena.pl/product/22111931/4-channel-solid-state-relay-5v-dc-low-level-trigger-power-switch-compatible-with-arduino-and-raspberry-pi 2026-03-16
