Relay Module 2 Channel 5V Active Low Trigger
The Relay 2 Channel Module 5V Active Low Trigger is a dual‑relay control board designed for reliable switching of AC and DC loads using low‑level logic signals from microcontrollers such as Arduino, PIC, ARM, AVR, and Raspberry Pi. Each of the two independent relays on the module is capable of handling up to 10 A of current for typical AC and DC electrical loads, making this board suitable for controlling lighting, motors, home appliances, and other medium‑power devices directly from low‑voltage logic outputs. The module features an active low‑level trigger, meaning the relay channels activate when a logic signal is pulled low (below typical thresholds), which provides intuitive compatibility with many embedded systems and GPIO interfaces.
Features:
- 2 independently controlled relays.
- Switch AC up to 125/250VAC @ 10A.
- Switch DC up to 28VDC/30VDC @ 10A.
- Normally Open (NO) and Normally Closed (NC) contacts.
- LED indicators when relays are energized.
- 5V logic compatible.
