This modules contains 2 relays, rated at 12V and 10A. Each relay has a LED indicator. It can be used to control various appliances, and other equipment with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Each relay has an Optocoupler, providing optical isolation. Each relay also have a freewheeling diode protection. This module has a 4 pin header(standard 2.54mm pitch) for connecting power (12V and GND), and controlling the 2 relays. These pins have the following functions:

  • IN1 to IN2: Controls relays 1 to 2, active Low! Relay will turn on when this input goes below about 2.0V
  • GND: Connect 0V to this pin. Is used to power the board (optocouplers and relays)
  • VCC: Connect 12V to this pin. Is used to power the board (optocouplers and relays)

For liability and safety reasons we DO NOT recommend using this module with voltages above 24V. Any use of this module is at your own risk! Always take necessary safety precautions when working with high voltages to prevent electrical shock! We will take no responsibility for any damage, personal injury or death incurred due to using this unit with high voltages!

Please note: The relays used are normally Songle or Tongling, which are both good quality and have the same specifications. During shipping to us from Asia, these modules some times get small scratches on top of the relays (from the other boards rubbing against them).
