Features：
1, Three button switches on module control different relays separately. Supports external connect momentary switches, supports wire connections length up to 10 meters/32 feet, of course, you can also connect longer wires, which need to consider the electrical interference of your application environment.
2, Power supply LED indication, LED indication for per each relay action.
3, Operating voltage DC 5V / 12V / 24V selectable. Three power relay SPDT(single pole double throw) switch output, support maximum voltage 250VAC / 30VDC, maximum current 10 Amp(per relay).
4, ABS plastic enclosure, you can use screw mount to wood board or wall, of course, can also be placed on the desktop.
5, High quality screw terminal block. Pitch 5.0mm/0.197". Wire range 26AWG ~ 12AWG / 2.5mm square.
Function Description(Example for channel 1):
1, Connect the DC-IN power supply, PWR LED turn to on, other LED all off, all relay output switches Cx to NOx disconnect and Cx to NCx connected.
2, Click button 1 or external momentary switch 1, LED 1 will turn to on, C1 to NO1 will connected and C1 to NC1 disconnect.
3, Click again button 1 or external momentary switch 1, LED 1 will turn to off, C1 to NO1 will disconnected and C1 to NC1 connected.
4, Continue to click button 1 or external momentary switch 1, the above step 2 and 3 actions will be repeated alternately.
Note: the product no power-off memory function, when the DC-IN is turned off, all the relay switches will return to the original state, Cx to NOx disconnect and Cx to NCx connected.
