Module with 4 relays and built-in ULN2003 system. It allows you to switch devices with high power, voltage 12 V and current up to 7 A using, for example, a microcontroller. All relay terminals (C, NC, NO) are available on screw terminals, which makes it very easy to connect the board. Perfect for automation systems that require the control of multiple devices.
