This modules contains 2 relays, rated at 5V 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 (5V 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 5V to this pin. Is used to power the board (optocouplers and relays)

There is a second 1×3 (2.54mm pitch) pin header for supplying the “relay side” of the board with 5V. At delivery, a jumper is present on this header selecting the 5V signal from main pin header to power the relays. For default operation, don’t change this jumper!
The pins of the 1×3 pin header are marked on the PCB:

  • JD-VCC – This is the 5V required for the relays. At delivery, a jumper is present on this and the adjacent (VCC) pin
  • VCC – This is the 5V VCC supplied on the main pin connector
  • GND – Connected to 0V pin of main pin header

If opto isolation is required, an isolated 5V supply should be used. For normal operation, a jumper bewtween pins 1 and 2 selects the 5V signal from the main pin header. This means both the “input side”, and “relay side” use the same 5V supply, and there is no opto-isolation.

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).
