POWERFUL SWITCHING CAPABILITY: Controls circuits up to DC 3A/30V or AC 3A/220V, functioning as an automatic switch using small current to control larger current for safety protection and circuit switching.
^^ SINGLE BUS CONTROL: Simple GPIO programming allows you to output high or low levels to connect the common terminal COM to either ON or OFF pins for easy relay operation.
^^ PROGRAMMABLE INDICATOR: Has 4 Built in, Programmable, Blue Status indicator LEDs, 1 for each realy.
^^ LOW POWER CONSUMPTION: Operates at 5V with only 40mA power draw, featuring fast coil action time of 6ms and release time of 4ms for responsive switching.
^^ VERSATILE DEVELOPMENT SUPPORT: Compatible with Arduino, UIFlow Blockly, and Python programming platforms, making it ideal for automation projects and DIY electronics applications.
