Our relay controller box (with remote control) just arrived! Here is an overview of the components. The relay comes with a set of numbered wires, each helping to relay the signal when a specific button on the remote control is pressed.
Below is the wire mapping on the relay box. For example, wires 1 and 2 are connected to the power supply to provide power to the relay box. As for wire 6, when the number 6 on the remote control is pressed, an electrical signal will be sent to wire 6 (with wire 5 as the ground). Wire 6 can then be connected to one of the actuators, resulting in that actuator extending.
Below is our compilation of the different wires that must be connected to transmit signals when the corresponding buttons on the remote control are pressed.
This is a close-up of the remote.
This is a close-up of the wires of the relay system, which have to be connected with the actuators.
The last component needed is the DC motor controller module. After manually connecting the wires to the DC motor controller module and then to one actuator and some troubleshooting, we managed to control the actuator’s extension/retraction using two buttons on the remote control. Pressing up on the remote control sends an electrical signal to wire 6, passing to the DC motor controller module, which then sends a positive signal to the actuator and then back to ground via wire 5. This extends the actuator.
In contrast, pressing down sends an electrical signal to wire 7, passing to the DC motor controller module, which then sends a negative signal to the actuator and back to the ground via wire 5. This retracts the actuator. The video below shows the actuator responding correctly to the up and down buttons.
