8-Channel 12V 10A Relay Module Low-Level (0V) Triggered for Arduino

8-Channel 12V 10A Relay Module Low-Level (0V) Triggered Eight-channel relay module powered at 12V, designed for direct control from platforms such as Arduino, AVR, PIC, DSP, and ARM. It also works very well with ESP8266, ESP32, and Raspberry Pi. To get started, simply connect the module to power and route the control signal to the IN1-IN8 inputs. The device includes LED diodes that continuously indicate the operating state of each of the eight relays. An additional advantage is the ability to safely test applications without physically energizing the load circuits. Removing the JD-VCC jumper disconnects power to the relay coils while the indicator LEDs still correctly show the logic state of each pin. Key technical specifications
