4. Setup Instructions
4.1. Power and Load Wiring
Ensure the module is powered with the correct DC voltage (5V, 12V, or 24V) corresponding to your specific module version. Connect your loads to the relay terminals. Each relay has three terminals: Normally Open (NO), Common (COM), and Normally Closed (NC). Refer to the wiring diagram below for proper connections.
Figure 2: Detailed Wiring Diagram
Wiring Notes:
- Connect the DC power supply to the module's input terminals (marked + and -).
- For each channel (A, B, C, D), connect your load to the COM terminal and either the NO or NC terminal, depending on your desired default state.
- For motor control, refer to the diagram for connecting the motor to two relay channels to enable forward and reverse operation.
4.2. App Download and Installation
The control application is available for Android devices only.
- Scan the QR code below with your Android smartphone or navigate to the provided URL to download the application.

5.2. Controlling Relays
The app provides an interface to control each of the four relays. You can switch them ON/OFF individually.
5.3. Setting Operating Modes
The module supports three main operating modes, configurable via the app:
- Jog Mode: The relay activates only while the button in the app is pressed and deactivates upon release.
- Self-lock Mode: Pressing the button toggles the relay state (ON/OFF).
- Interlock Mode: Only one relay in a group can be active at a time. Activating one relay will deactivate any other active relay in the same group. This is useful for applications like motor forward/reverse control.
