The BMT Relay Board 1CH 12V 30A High Duty is a single-channel relay module built for high-current switching in Arduino and other microcontroller projects. It uses a genuine 30A relay with opto-isolated input to keep your low-voltage control circuit safely separated from the high-current load, making it ideal for home automation, robotics, industrial equipment and DIY electronics or IoT builds.
Key Features:
- Genuine 30A relay for reliable high-current switching
- Opto-isolated input protects your microcontroller from load-side voltage
- Supports both Normally Open (N/O) and Normally Closed (N/C) contacts
- Low 5mA trigger current, compatible with Arduino and other microcontrollers
- High-level or low-level triggering via jumper selection
- Screw terminal blocks for secure, easy wiring
- Compact, robust design with module holder and mounting holes for straightforward installation
Specifications:
- Operating Voltage: 12V DC
