Description:

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: for , UIFlow(Blockly,Python)
  • Two Le go-compatible holes
  • Product Size: 48.2mm x 24.2mm x 21.4mm
  • Product weight: 11.7g
