4 Road/Channel Relay Module 12V
This 4-Channel Relay Module (with optical coupling) operates at 12V and adheres to safety standards, featuring an isolation groove between the control area and the load area for enhanced protection. The optical coupling ensures reliable and stable triggering of the relays.
The module boasts a double FR-4 circuit board design and high-quality SMT processing. It includes indicators for power and relay operation, while the relay terminals (C, NC, NO) are easily accessible via screw terminals, simplifying the wiring process.
The inputs of the 4-Channel 12V Relay Module are isolated to safeguard sensitive control circuitry. It is compatible with a wide range of microcontrollers, including Arduino, AVR, PIC, and ARM.
Using high-voltage relays minimizes the risk of overheating, as electromechanical relays regulate current consumption based on their voltage rating.
