Dola 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.

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

Asked by BG241166535 on 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.

Q: How much the long range?

Asked by BG498502394 on 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.

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.

Press then

Q: What is the MCU (the IC)?

Asked by buttim on 2019-06-17 08:08:21

Dola IC is GY8PE531MAD

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.

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

Asked by Jettochkin on 2018-07-30 11:26:47

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

Dola Sure. It should be 7...12V DC power supply with 5,5/2,1 connector and the middle is the positive.

Q: Is battery removable?

Asked by Johan on 2021-08-16 06:53:04

Dola Battery is not removable. This is a lightweight plastic toy (lamp). The description is misleading because it is not a powerbank! It is not waterproof! It has no blue LED, only red and it does not indicate when the battery is low. It can not be 10W-3W! I compared it with other LED lamp, it seems 1-2 Watt only :(. The focused light last for 3 hours or the side lights last for 2 hours. Not worth buying. I regretted this purchase.

Dola My recommendation: First measure the output voltage without load (pump). If you measure less than 12V DC, the power supply is faulty. If you measure 12-13,5V, connect the pump; measure the voltage again. If you measure less than 12V DC, the power supply is faulty. Please note, I also bought one and it can deliver maximum 100mA! Not 300mA!

Dola XH-M301 (ZFX-M301): The rated output voltage is 12V DC. They say it can deliver up to 300mA, but not! It can deliver maximum 100mA! Measurements: 13,5V @ 0mA; 12,0V @ 100mA; 7,5V @ 110mA
