5V relay module with a NE555 (timer) IC. By adding this timer it is possible to set a delay of 0 to 10 seconds before this relay switches on. The module is initially off and turns on after X seconds. You can also use the NC output, this input is connected in the beginning and turns off after X seconds. The status is not reset until the power is removed from the module. Connection diagram: The terminal block next to the relay has 3 connection points NC, COM and NO. On the other side is the input (+ and -). The + is closest to the capacitor and is marked with + or VCC. https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2025-01-22 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2025-05-11 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2025-05-12 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2026-02-20 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2026-03-11 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2026-03-13 https://elecena.pl/product/27738868/opencircuit-5v-relay-with-adjustable-delay-0s-10s 2026-04-11
