1The Tapo S110E relay module connects via Wi-Fi and Bluetooth, operating in dry or wet contact modes based on wiring.

*AC stands for alternating current and DC stands for direct current.
Wiring Instructions
• Wet Contact Mode (Figure 1): Use the short wire provided to connect the "I" terminal to the "W" terminal.
• Dry Contact Mode (On/Off Mode) (Figure 2): Connect the “O” terminal and the “I” terminal to the load circuit. Connect the L (DC-) and N (DC+) terminals to the input of the power supply.
• Dry Contact Mode (Pulse Mode) (Figure 3): The switch module sends a short pulse signal through the “I” and “O” terminals.
Note

English: Safety Information
Before installing, servicing or removing the switch module, read and follow all safety precautions including the following:
• Follow all national and local safety regulations and practices. If you are uncertain or uncomfortable when performing the installation, consult a qualified electrician.
• CAUTION – Risk of Electric Shock – An all-pole disconnect device may be required to de-energize the equipment before servicing. A circuit breaker which disconnects the Line and Neutral conductor simultaneously is suitable. Ensure power is off at the circuit breaker before removing or installing any switch module. Use a non-contact voltage tester to ensure the power is off.
