The 2 Channel 12V Relay Module with Optocoupler is a reliable and safe relay board designed with optical isolation to protect sensitive control circuitry. With clear separation between the control area and load area, it ensures stable and secure operation in various applications.
This module uses a double-sided FR4 circuit board and high-quality SMT process for durability. It features LED indicators for power and relay status, along with screw terminals (C, NC, NO) for easy wiring.
It can be controlled directly by popular microcontrollers such as Arduino, AVR, PIC, ARM, and more, making it perfect for both hobby and industrial projects.
Features:
Equipped with high-current relay: 10A @ 250V AC / 10A @ 30V DC
Compatible with both AC and DC loads (motors, solenoids, lights, fans, etc.)
