Well-made product. It works nicely. I recommend! Of course you need an external 12V DC power supply for the receiver but the remote controllers have batteries. Transmitters: 12*32*57mm; 17g (21g with holder) Receiver: 29*54*75mm; 67g; Electronics: 47*67*17mm; holes: o3,2mm 42*62mm. Three operating modes, can be set with a jumper: 1. Self-lock (T) - jumper is on pins 1-2 (inside): When a button is pressed for the first time, the relevant relay (A/B/C/D) turns ON, when same button is pressed again, relay switches OFF. The 4 relays can be used independently. Only one button can be operated at the same time, pressed one after the other, works nicely. 2. Jog (M) - jumper is removed: As long as the button is pressed, the relay is ON, when the button is released the relay switches OFF. The 4 buttons can be used independently and simultaneously. 3. Inter-lock (L) - jumper is on pins 2-3 (at edge): When the first button is pressed, the given relay turns ON, when another button is pressed, this relay switches OFF and the other turns ON. After the first press, one relay is always ON. When you press several buttons at the same time, the first one is ON all the time, the others are ON only until you press the button. Operating voltage: DC 12V (from 10V to 15V) Operating and idle current: 8mA when all relays are off (at 10…15V). Operating current at 10V with 1 relay ON: 43mA; 2 ON: 76mA; 3 ON: 110mA; 4 ON: 140mA Operating current at 12V with 1 relay ON: 51mA; 2 ON: 95mA; 3 ON: 135mA; 4 ON: 177mA Operating current at 15V with 1 relay ON: 63mA; 2 ON: 116mA; 3 ON: 166mA; 4 ON: 220mA Pairing the receiver and the transmitter: Power on the receiver. Press then release the “Learning button”, LED turns off. Press then release any button of the transmitter. The LED flashes three times. Done. Repeat it with all transmitter. Delete all pairing: Power on the receiver. Press and hold the “Learning button” for 8 seconds. Done. Perfect for DIY projects! :)

Ερ: Can it be installed to open and close the room door?

Ερώτηση από BG241166535 επί 2021-12-11 12:12:21

Dola Yes. The wiring is depends on the lock. Most cases the Jog (M) mode will work fine: jumper is removed: As long as the button is pressed, the relay is ON, when the button is released the relay switches OFF. The 4 buttons can be used independently and simultaneously.

Ερ: How much the long range?

Ερώτηση από BG498502394 επί 2020-06-25 12:53:01

Dola Mine works well from about 20 meters in town. No more.

Dola Operating voltage: DC 12V (from 10V to 15V) Operating and idle current: 8mA when all relays are off (at 10…15V). Operating current at 10V with 1 relay ON: 43mA; 2 ON: 76mA; 3 ON: 110mA; 4 ON: 140mA Operating current at 12V with 1 relay ON: 51mA; 2 ON: 95mA; 3 ON: 135mA; 4 ON: 177mA Operating current at 15V with 1 relay ON: 63mA; 2 ON: 116mA; 3 ON: 166mA; 4 ON: 220mA So if no one relay is ON, the battery will last for very long time (more than 100 days), but if 4 relays are ON, the battery will last for 10-15 days.

Ερ: Can this be wired for a 12v motor forward and reverse ? Reverse polarity switch?

Ερώτηση από c smith επί 2022-03-20 03:49:33

Dola Yes, as you can see on a photo (see 2 DC Motor), but you have to user 2 relay for 1 motor. Use Self lock mode: Three operating modes, can be set with a jumper: 1. Self-lock (T) - jumper is on pins 1-2 (inside): When a button is pressed for the first time, the relevant relay (A B C D) turns ON, when same button is pressed again, relay switches OFF. The 4 relays can be used independently. Only one button can be operated at the same time, pressed one after the other, works nicely. 2.

Press then

Ερ: What is the minimum voltage ? I would like to use it on 5 voltage device.

Ερώτηση από middy επί 2021-10-09 03:49:27

Dola The electronics required 9 to 15V DC and it use max 40mA current. So, you can NOT use it from 5V power supply. With the relay you can switch voltage between 0,1 and 230V and up to 10 Ampers.

Dola When 12V operating power is interrupted, the switch goes OFF and when receive power again it is stays in OFF till you push the ON push-button.

Ερ: what is the current consumption in the standby state?

Ερώτηση από Jettochkin επί 2018-07-30 11:26:47

Dola at mine: 9 mA at idle and 40 mA when the relay pulled in.
