Gravity 16A Digital Relay Module
Overview
The DFR0251 is a high-current electromechanical relay module designed for the DFRobot Gravity ecosystem, featuring a Hongfa HF152FD relay. It allows low-power microcontrollers to switch high-power loads up to 16A at 24V DC or 250V AC. The module is 5V tolerant and uses a standard digital signal for control, making it accessible for rapid prototyping in automation and robotics.
Why Choose This Part
This module provides a plug-and-play solution for switching up to 16A, significantly higher than typical hobbyist relay boards. It features a Gravity-standard 3-pin interface for solderless connectivity and includes onboard status LEDs to provide immediate visual feedback of the relay state.
Applications
Key Specifications
Getting Started
Connect the module to any digital I/O pin on a Gravity-compatible expansion shield or microcontroller using the included 3-pin cable. Set the target pin as an OUTPUT in your firmware; pulling the pin HIGH will trigger the relay coil and close the contact. Ensure the switched load does not exceed 16A and follow appropriate high-voltage safety practices when wiring the terminal blocks.
