Built around the industry-trusted JQC-3FF-S-Z power relay, this compact interface board bridges the gap between delicate low-voltage microcontrollers and heavy-duty electrical circuits. Available in both 5V DC and 12V DC coil voltage options, this module allows you to switch household voltages and industrial loads with total peace of mind.
Whether you are designing an automated internet-of-things (IoT) ecosystem, a custom CNC interface, or a home automation setup, this module provides the heavy-duty isolated switching your project requires.
Key Features & Technical Highlights
- Genuine Tongling JQC-3FF-S-Z Relay: Features a high-quality, flame-retardant relay core designed for long contact life, excellent electrical conductivity, and rapid mechanical switching response.
- Dual LED Operational Monitoring:
- PWR (Red LED): Illuminates to instantly confirm that power is safely supplied to the board logic.
- Status (Green LED): Brightly lights up only when the control pin is triggered, confirming the relay coil is active.
- Dual-Voltage Variations Available: Optimally configured for either 5V DC control logic (perfect for direct microcontroller pinning) or 12V DC supply networks (ideal for automotive and industrial power rails).
- Industrial Blue Screw Terminals: Outfitted with durable 3-pin screw clamp terminal blocks. The heavy-gauge terminals prevent wire slippage and provide solid contact points for the output paths: Normally Open (NO), Common (COM), and Normally Closed (NC).
- Compact, Breadboard-Friendly Footprint: Small-form factor circuit board design integrates seamlessly into cramped project enclosures, custom PCBs, or prototype layouts.
