Key Features of DC 6V To 30V One Way Relay Module
- Wide Input Voltage Range: Accepts 6V to 30V DC trigger/power supply, making it compatible with a broad range of battery packs, power adapters, and microcontroller systems.
- Optocoupler Isolation: Electrically isolates the control signal from the relay coil and load circuit, protecting sensitive microcontrollers like Arduino, ESP32, and Raspberry Pi from voltage spikes and back-EMF.
- High-Current Switching: Rated to switch loads up to 10A at 250V AC or 10A at 30V DC, suitable for controlling motors, solenoids, heaters, pumps, lighting, and household appliances.
- Three-Terminal Output (NO/NC/COM): Provides both Normally Open and Normally Closed contacts for maximum wiring flexibility in different switching scenarios.
- Configurable Trigger Level: Supports both high-level and low-level triggering via onboard jumper, ensuring compatibility with virtually any microcontroller logic.
- Dual Status LEDs: Onboard power indicator and relay activation LED give clear visual feedback for easy debugging and monitoring.
- Tech Depot India Screw Terminals: Heavy-duty screw terminals on the load side ensure secure, vibration-resistant connections for high-current wiring without soldering.
- Compact & Mountable: Small PCB footprint with mounting holes for easy integration into enclosures, panels, and project housings.
- Flyback Diode Protection: Built-in freewheeling diode across the relay coil suppresses inductive voltage spikes during switching, extending relay and circuit lifespan.
- 100% authentic from trusted suppliers - no clones or substandard components
- Wide 6V-30V operating range eliminates the need for dedicated voltage regulators in many setups
- Optocoupler isolation safeguards your expensive development boards and microcontrollers
- Battle-tested relay design trusted in thousands of automation and IoT deployments
