Art Controller Relay Board Kit

Stand-alone relay module with onboard microcontroller for timing and logic control. Switches AC or DC loads via relay and is reprogrammable for custom trigger/delay applications such as coin-operated activation or timed sequencing.

Relay COM
Common terminal of the SPDT relay output terminal block. Adafruit says COM is connected to NC when idle and to NO when the coil is energised.
Type · UnknownVoltage · Recommended load rating 24 V DC / 40 VAC, 5 A; NO contact 10 A only, per Adafruit product page.
Relay NC
Normally-closed relay terminal. Connected to COM when the relay coil is idle or power is removed, per Adafruit product page.
Type · UnknownVoltage · Relay contact load terminal, see COM rating.
Relay NO
Normally-open relay terminal. Connected to COM when the relay coil is energised, per Adafruit product page.
Type · UnknownVoltage · Relay contact load terminal, see COM rating; Adafruit notes 10 A normally-open only.
Trigger input
Two-pin trigger input for a normally-open button/switch or external low-going logic signal; closing the two trigger pins starts the controller cycle.
Type · GPIOVoltage · Logic/input terminal; product page says low-going signal is perceived like a button press.
Input power
Screw terminal input power for the Art Controller microcontroller and relay.
Type · PowerVoltage · Runs from 7-15 V DC through onboard regulator, or 5 V directly, per Adafruit product page.
Cancel Trigger
Auxiliary low-going input that reverts the controller to idle and can prevent new triggers when held low.
Type · GPIOVoltage · Configuration/logic input, held low or connected to ground per Adafruit product page.
Trigger @ Reset
Configuration jumper pin. Soldering this pin to ground makes the controller trigger on power-up.
Type · ControlVoltage · Jumper to ground per Adafruit product page.
StartStop on Trigger
Configuration jumper pin. Soldering this pin to ground makes a second trigger act as cancel/stop.
Type · ControlVoltage · Jumper to ground per Adafruit product page.
Repeat
Configuration jumper pin. Soldering this pin to ground makes the relay cycle repeat with on/off delay periods.
Type · ControlVoltage · Jumper to ground per Adafruit product page.
