2-Channel 12V Relay Module Active High

2-Channel 12V Active High Relay Module

The 2-Channel 12V Relay Module (Active High) provides independent control of two electrical loads using a 12V DC input signal. Each channel activates when the input signal is driven high, making it suitable for controllers or systems configured with high-level triggers.

This relay module supports both AC and DC loads up to 10A, enabling reliable switching in home automation, industrial automation, robotics, and IoT projects. With opto-isolators included for protection and flyback diodes to suppress voltage spikes, it safeguards sensitive controllers and ensures long-term durability.

Compact and versatile, this dual relay module integrates easily with Arduino, Raspberry Pi, ESP32, PIC, and AVR microcontrollers, making it a strong choice for hobbyist and professional electronic designs.
