Specifications

Key Features

• Dual Independent Channels: Control two separate high-power loads simultaneously with individual relay outputs and dedicated input pins.
• Optocoupler Isolation: Built-in optocouplers electrically isolate the microcontroller side from the relay coil and high-voltage switching side, protecting your development board from voltage spikes and noise.
• High-Current Switching: Each relay can handle up to 10A at 250V AC or 10A at 30V DC - powerful enough to switch lights, fans, motors, heaters, solenoid valves, and more.
• Low-Level Trigger (Active LOW): Relays activate when the input pin is pulled LOW, making it directly compatible with most microcontrollers including 3.3V logic boards like ESP32 and Raspberry Pi.
• SPDT Relay Configuration: Each channel provides Normally Open (NO), Normally Closed (NC), and Common (COM) screw terminals, giving you flexibility to wire devices in either fail-safe or fail-secure configurations.
• LED Status Indicators: Individual red LEDs on each channel provide instant visual confirmation of relay state - easily verify operation during development and debugging.
• Flyback Diode Protection: Integrated freewheeling diodes suppress voltage spikes generated when the relay coil de-energizes, extending the lifespan of both the relay and your driving circuitry.
• Screw Terminal Outputs: Secure, tool-tightened screw terminals ensure reliable connections for high-current wiring without soldering.
• Compact & Mountable: Small form factor with four M3 mounting holes allows easy integration into enclosures, control panels, and prototype housings.
• Breadboard & Jumper Friendly: Standard 2.54mm pitch header pins on the input side connect directly to jumper wires and breadboards for rapid prototyping.
