1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the YIOGEQKWG WS-DMX-RELAY-12CH-10A DMX512 12-Channel Relay Switch Controller. This device is designed for industrial applications requiring DMX512 control over multiple electrical loads. Please read this manual thoroughly before use to ensure proper function and safety.
2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the device and connected equipment:
- Power Supply: Ensure the power supply voltage is DC12V. Connecting an incorrect voltage can damage the unit.
- Electrical Loads: Do not exceed the maximum current rating of 10A per relay channel. Overloading can cause overheating and damage.
- Installation: Installation should be performed by qualified personnel. Ensure all wiring is secure and correctly connected.
- Environment: Operate the device within the specified temperature range (-20℃ to 60℃). Avoid exposure to moisture, dust, and corrosive substances.
- Maintenance: Disconnect power before performing any maintenance or cleaning.
3. Product Overview
The WS-DMX-RELAY-12CH-10A is a DMX512-controlled relay module featuring 12 independent relay channels. Each channel can switch electrical loads up to 10A. The module includes DMX input/output ports, Ethernet ports (for potential future or alternative control, though primarily DMX512), a DC12V power input, and DIP switches for DMX address configuration.

5. Setup
5.1 Unpacking
Carefully remove the relay controller from its packaging. Inspect the unit for any signs of physical damage. Ensure all components are present.
5.2 Mounting
Mount the controller in a secure location, away from excessive heat, moisture, and vibration. Ensure adequate ventilation around the unit.
5.3 Wiring Connections
Refer to Figure 1 for component locations. Ensure power is disconnected before making any wiring connections.
- DC12V Power Input: Connect a stable DC12V power supply to the designated green screw terminal block labeled 'DC12V'. Observe correct polarity (+ and -).
- DMX512 Input/Output: Connect your DMX512 controller to the 'DMX IN' XLR port. If daisy-chaining to other DMX devices, use the 'DMX OUT' XLR port.
- Relay Outputs: Connect your electrical loads (e.g., lights, motors) to the 12 sets of green screw terminal blocks. Each set corresponds to one relay channel (K1 to K12). Each relay provides normally open (NO) and common (COM) contacts. Wire your load between the COM and NO terminals for switched operation.
5.4 DMX Address Configuration (DIP Switches)
The DMX start address is set using the red DIP switches. Each switch corresponds to a binary value. To calculate the DMX address, sum the values of the switches set to 'ON'.
- Switch 1: 1
- Switch 2: 2
- Switch 3: 4
- Switch 4: 8
- Switch 5: 16
- Switch 6: 32
- Switch 7: 64
- Switch 8: 128
- Switch 9: 256
For example, to set the DMX address to 1, set only Switch 1 to 'ON'. To set the address to 3, set Switch 1 and Switch 2 to 'ON'.
6. Operating Instructions
Once all connections are made and the DMX address is set:
- Apply DC12V power to the controller.
- Ensure your DMX512 controller is powered on and transmitting a DMX signal.
- The WS-DMX-RELAY-12CH-10A will receive the DMX signal. Each of the 12 relay channels corresponds to a DMX channel starting from the configured DMX address.
- Typically, a DMX value above a certain threshold (e.g., 128 or 50%) will activate the corresponding relay, while a value below the threshold will deactivate it. Consult your DMX controller's manual for specific output values.
7. Maintenance
The WS-DMX-RELAY-12CH-10A is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:
- Cleaning: Keep the unit clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Environment: Ensure the operating environment remains within the specified temperature and humidity limits.
8. Troubleshooting
- No Power Indicator:
- Check the DC12V power supply connection and ensure it is providing the correct voltage.
- Verify power supply functionality.
- Relays Not Switching:
- Confirm the DMX512 controller is sending a signal.
- Verify the DMX start address on the DIP switches matches the address configured on your DMX controller.
- Check DMX cable connections for continuity and correct wiring.
- Ensure the DMX values for the corresponding channels are above the activation threshold.
- Incorrect Relay Operation:
- Double-check the DMX address setting.
- Ensure no other DMX devices are using the same address range.
