Description:
12V relay to control 30A current
Can be use as development template of singlechip, and use as household appliances control
5V-12V of TTL control signal
Control of direct current signal/AC signal, and control the 220V alternating load
Circuit board: Approx. 28mm X 61mm / 1.1 x 2.4 inch
Location hole: Approx. 22.8mm X 55.8mm / 0.9 x 2.2 inch
The heart of the board is a sealed, SONGLE 30A Relay. The relay need a 12VDC power supply . The relay is controlled by 12V or 5V logic through a transistor and an LED tells you when the relay is closed. This is a kit, so it comes as through-hole parts with assembly required which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project
Note: There are some pretty beefy traces connecting the relay to the load pins, but the 2-pin terminals are only rated for 16A max! If you plan on connecting a larger load you'll need to solder directly to the board. As always with high current and voltage, play it safe and use you judgment when deciding how much of a load you want to put on a board
Note: Although we have revised this PCB to provide better isolation for the high voltage traces, this board is really meant for someone with some experience
Package Includes:
1 x 30A relay module
