Operating Modes:
| Mode | Description |
|---|---|
| Momentary Mode | The relay remains ON only while the remote button is being pressed. Once the button is released, the relay automatically turns OFF. Ideal for door locks, gates, and temporary control applications. |
| Self-Locking Mode (Toggle Mode) | Each press of the remote button changes the relay state. Press once to turn the relay ON, and press again to turn it OFF. Commonly used for lighting, pumps, and general appliance control. |
| Interlock Mode | When multiple control buttons are used, activating one output automatically deactivates the others. This prevents two outputs from being ON simultaneously and is commonly used for motor forward/reverse control and directional switching. |
| Delay Mode | The relay turns ON or OFF for a preset period after receiving a trigger signal, then automatically changes state when the timer expires. Suitable for timed lighting, access control systems, and automation projects. |
| Strobe Mode | The relay repeatedly switches ON and OFF at a defined interval while activated. This mode is useful for flashing lights, alarm indicators, warning systems, and signal generation applications. |
