This relay module can be signal triggered low or high, selectable from the jumper pin on-board. It can be controlled directly by the microcontroller, with a 3.3V signal. The inputs are opto-isolated to protect any delicate control circuitry. An LED indicator will turn on together with the relay when triggered.
The relay module is able to control various appliances and other equipment with a large current. Relay output maximum contact is AC 250V 10A or DC 30V 10A. Each channel consumes about 15 - 20mA current when active.
This relay module is perfect for 3.3V microcontrollers such as Raspberry Pi, ESP8266, ESP32, 3.3V Arduino boards, etc.
