RELAY, as its namesake, is a M5Unit that implenments a Relay functions. Relay can be used as an electrically operated switch, uses an electromagnet to mechanically operate a switch,to where it is necessary to control a large power load circuit by a separate low-power signal, like a digital signal output from a mircoprocessor. Up to 30V DC and 220V AC.
There are 3 pins named: ON, OFF, COM. You can program to make COM connect to ON or OFF, just by high and low out put of a digital GPIO.
- Single-BUS control
- Up to 3A @ 30 V DC or 220 V AC
- Software Development Platform: Arduino, UIFlow(Blockly,Python)
- Two Lego-compatible holes
- Remote control of high-power appliances, such as refrigerators, Air Conditioners, TVs, etc.
