Single Relay Module for Arduino
This board features a SPDT relay that can be controlled directly from the digital output pins on the Arduino or other microcontroller. The relay module has a built-in transistor and clamping diode, and an LED lights up when the relay coil is energized. This is a great and inexpensive way to switch on or off AC or DC loads using your Arduino! And its now opto-isolated!
This board is simple to hook up, the 3-Pin male header carries a 5VDC coil voltage and the "on" input signal. An external load is connected via a set of sturdy screw terminals. Terminals are provided for both normally closed and normally open operation.

The part numbers shown in the photos are not necessarily the part numbers you will receive. In fact, you should NOT assume that you will get any part numbers shown in the photos. These are imported items and the manufacturers do NOT tell us what the individual component part numbers are ahead of time. This is not something that we can special request. It is also not possible for us to routinely update the pictures on our website for incidental individual component part number differences. However, the item you receive, as a whole, will be exactly as functional as the one listed in the description. There will be color differences, board sizes differences and or individual component differences. If you have special requirements, you MUST contact us BEFORE ordering or immediately afterwards. We are here to, and can help!
