Current Capacity of MyQ motor


Does anyone know the specs of the power connection for keypads and buttons? I’m looking to know more about how many devices can be connected in parallel to that terminal. I currently have 1x 889LM keypad connected and would like to know how many of these types of devices the motor can support to supply power to.

Obviously, the current draw of each device also plays into this but I gotta start with the supply side and work backwards.

This is something that Liftmaster’s technical support should be able to answer.
From the features 889LM console offers I would imagine it draws quite a bit more of parasitic power comparing to a regular wall button like 87LM which only uses power for an LED light.
