In the picture attached, there are 3 actuators connected to a driver module. However, I need to connect just one actuator in parallel to three of these channels (i.e. 1,2,3). The reason ...I need a 3.6A drive and each channel only provides 1.2A. Any idea how to wire the single actuator in parallel to these 3 channels?
Just connect 1 to 2 to 3 and then to your single load. You will have to change the coding/software/programming of the device such that outputs 1,2,&3 all turn on and off at the same time.
