This 1 Channel 12V Relay Module with Optocoupler meets safety standards with isolation grooves between control and load areas. The module features a reliable triggering mechanism and a high-end SMT design. The relay is driven by a transistor BC547 for added protection to input devices like Arduino.
The inputs are isolated to safeguard delicate control circuitry. It is compatible with various microcontrollers such as Arduino, AVR, PIC, ARM, etc. The high-voltage relay reduces the risk of overheating compared to electromechanical relays.
Module Interface:
- Positive (VCC): Connect power supply
- GND: Connect power negative
- IN: Relay module high-level trigger signal
Meaning of High level and Low-level:
- High-level trigger: Anode voltage at VCC connection for triggering
- Low-level trigger: Negative voltage at GND connection for triggering
The 1 Channel 12V Relay Module can directly control various equipment and loads. It includes a freewheeling diode for microcontroller protection and LED status indicators for relay status.
Package includes: 1 x 1 Channel 12V Relay Module with Optocoupler
