4.3 Elektroinstalācijas shēmas
The module supports various wiring configurations depending on the application and desired working mode. Always ensure correct polarity and voltage.

Image 4.1: Wiring for Interlock mode, demonstrating connections for both DC (5-30V) and AC (90-250V) motors or appliances. This mode ensures only one relay is active at a time.

Image 4.2: Wiring for Momentary mode, suitable for applications like garage door openers or momentary button presses. Input power is typically 5V via Micro USB.

Image 4.3: Wiring for Self-locking mode, ideal for controlling lights or other devices that require a sustained ON/OFF state. Input power can be AC/DC 7-32V.
Refer to the specific application's voltage requirements and connect the load to the appropriate COM and NO (Normally Open) or NC (Normally Closed) terminals on the relay. The module can be powered via a Micro USB 5V input or directly through the AC/DC 7-32V terminals.
4.4 Device Pairing with App
- Power on the Newgoal DC2-Tuya module using either the Micro USB 5V or AC/DC 7-32V input.
- Open the TUYA Smart or Smart Life App.
- Press and hold the "Work Modes Toggle Button" (often labeled Key1 or Key2, or a dedicated pairing button) on the module for approximately 6 seconds until the WiFi LED indicator starts blinking rapidly. This indicates the module is in pairing mode.
- In the app, tap the "Add Device" (+) icon, usually located in the top right corner.
- Select the device type (e.g., "Switch" or "Electrical Switch"). The app may automatically discover the device.
- Follow the on-screen instructions to connect the module to your 2.4GHz WiFi network. You will need to enter your WiFi network password.
- Once successfully paired, the WiFi LED on the module will stop blinking and remain solid. You can then rename the device and individual channels within the app for easier identification.
5. Lietošanas instrukcijas
5.1 Darba režīmi
The module supports three primary working modes, configurable via the app or the physical "Work Modes Toggle Button" (long press for 6 seconds to enter setting mode, then short press to cycle through modes: 1 time for Momentary, 2 times for Self-locking, 3 times for Interlock). The Work Mode LED will indicate the selected mode.
- Momentālais režīms (pakāpenisks režīms): When activated, the relay turns on for a set duration (adjustable from 0.5 to 60 seconds) and then automatically turns off. This is suitable for applications requiring a brief pulse, such as garage door openers or electric strikes.
- Pašbloķēšanās režīms: Each relay acts as a standard ON/OFF switch. Pressing the button (in app or physical) toggles the relay state (ON or OFF). This is ideal for controlling lights or other devices that need to remain in a continuous state.
- Bloķēšanas režīms: In this mode, only one relay can be active at a time. If one relay is turned ON, any other active relay will automatically turn OFF. This is useful for controlling devices where simultaneous operation is undesirable, such as motor direction control.
