Can control sliding door motor?

[Paolo Trenti]

Hello, I have 12V sliding gate motor with two connection on is board: 1. full (to input full open and close command), 2. Ped ( to input pedestrian open and close).

I was thinking to use Shelly plus 2pm to control both inputs but all is 12v dc. Is it possible? Thanks

Could you please give us a link to the motor specs and/or the corresponding manual? Possibly, a Shelly UNI plus could solve the issue…

This is the manual with the board connections. Thanks for the help. 

Let's see what's new.pdf

Thanks for the link! The easiest way to solve this issue would IMHO be to use two Shelly plus 1:

 

The left Shelly controls the full opening of the gate, the right the pedestrian opening. Please be aware that a sufficient WLAN coverage at the location where the Shellies are intended to be mounted.

A second solution (with only one Shelly device) is depending from the assumption that the activating current at the pins FULL and PED(estrian) is lower than 350mA. This is very likely cause the control of the motor happens not directly, but via a specific electronic circuit.

Plan B is working with a Shelly UNI plus:

Thanks a lot for the useful info. So the shally plus 2pm is unuseful cause not work with 12vDC right? And if the all sister was 24vDC would it be ok? Thanks.

I read the specs of Shelly UNI and the 

Max switching current

is 250mA. Anyway can I misure it with tester? How?

A Shelly plus 2PM „off the shelf“ will not work with 12V DC. But after a modification (a wire and a diode will be added) the device will operate with 12V DC. If you are interested, I could send you a modified Shelly plus 2PM…

Switch your multimeter to current range (mA). Touch with the positive test tip pin 14 (FULL) and with the negative tip pin 19 (GND). The motor must now work. Read the current value. Do the same for pin 15 (PED) and 19 (GND).

Both values must be smaller than 250mA.

I tested the 2 contacts… both 350/360 mA 😭 So I must use 2 Shelly plus 1 right? Thanks a lot for your help!

not necessarily. It is also possible to connect 2 small relays to the outputs of the UNI, which then switch the load

[Paolo Trenti]

Is correct?

[thgoebel]

Thanks for the picture of the DMM! The current value of 3.6mA is most likely correct! Thus you may use a Shelly UNI or UNI plus without additional relays.

[Paolo Trenti]

Ahhh is only 3.6mA I thought was 360.  Sorry. So I’ll go with Shelly UNI plus. Thanks.
