XY-WJ01 one way relay delay timmer switch
This content will be shared across all product pages.
Description:
A compact module combining a programmable timer with an SPST relay for timed control of external devices. Activates/deactivates the relay after a set delay upon receiving a trigger signal.
Key Features:
- Controls one external device via the built-in SPST relay.
- Programmable delay to activate/deactivate the relay.
- Supports various trigger modes (button press, voltage level change, external switching signal).
- Wide DC voltage range (typically 6V to 30V).
- LCD display for configuration, monitoring delay, and viewing operating mode.
- Sleep mode for power conservation (dims display during inactivity).
- Memory function retains programmed settings after power cycles.
Technical Specifications (Refer to Datasheet):
- Operating Voltage: Typically 6V to 30V DC (exact range varies)
- Timing Range: Usually 0.01 seconds to 9999 minutes (specific range varies)
- Relay Output: SPST relay, typically rated for 30V DC at 10A or 220V AC at 5A (check datasheet)
- Display: LCD screen
- Dimensions: Refer to datasheet for specific model dimensions
Applications:
- Time-delayed control of lights, motors, or other devices.
- Automatic shutoff systems.
- Simple automation projects with timed relay activation.
- Educational tool for learning about timers and relay control.
