The DEWIN 12V Single Channel Bistable Relay Module is designed for control applications requiring a latching switch function. This module operates as a typical bistable circuit: a single trigger press activates the relay, and another press deactivates it. It features screw terminals for easy wiring and is suitable for various DC 12V control systems.

Varnostni ukrepi
- Ensure the power supply is DC 12V. Do not use in automotive environments where instantaneous voltage can exceed 12V.
- Pred kakršnimi koli priklopi ali nastavitvami vedno izklopite napajanje.
- Observe proper polarity when connecting the power supply (12V to positive, GND to negative).
- If operating in environments with strong electrical interference, consider adding a series diode at the input and a 470uF capacitor in parallel to GND for enhanced stability.
- This module is designed for low-level trigger signals.
Namestitev in ožičenje
The module features screw terminals for straightforward connections. Refer to the diagram below for proper wiring.
- Napajalni priključek: Connect the 12V positive power supply to the terminal labeled "12V". Connect the negative power supply (ground) to the terminal labeled "GND".
- Trigger Switch Connection: Connect your trigger switch to the terminals labeled "trigger switch". The module responds to a low-level trigger signal.
- Povezava obremenitve: The relay has three output terminals:
- COM: Skupni terminal.
- NE (običajno odprto): The circuit is open when the relay is inactive and closes when activated.
- NC (normalno zaprto): The circuit is closed when the relay is inactive and opens when activated.

Navodila za uporabo
This module operates as a bistable switch. Follow these steps to operate the relay:
- Ensure all wiring connections are secure and correct as per the "Setup and Wiring" section.
- Apply DC 12V power to the module. The red LED indicator may illuminate briefly or remain off depending on the initial state.
- To Activate the Relay: Press the connected trigger switch once. The relay will close (if using NO) or open (if using NC), and the red LED indicator will illuminate, indicating the relay is active.
- To Deactivate the Relay: Press the trigger switch again. The relay will return to its inactive state, and the red LED indicator will turn off.
This sequential operation allows for simple ON/OFF control with a single momentary switch.
Vzdrževanje
The DEWIN 12V Single Channel Bistable Relay Module is designed for reliable operation with minimal maintenance. Follow these guidelines:
- Modul naj bo čist in brez prahu ter vlage.
- Regularly inspect wiring connections to ensure they remain tight and secure.
- Izogibajte se izpostavljanju modula ekstremnim temperaturam ali neposredni sončni svetlobi.
- Do not attempt to repair the module if it is damaged. Contact support for assistance.
