12V 6 Channel with Light Coupling Relay Module
The 6-Channel Relay Module with light coupling operates at 12V and ensures safety compliance with isolation grooves separating control and load areas, along with optical coupling isolation modules.
Its reliable triggering mechanism and stable performance are supported by a double FR–4 circuit board design and high-end SMT processes. The module features clear power and relay operation indicators for user convenience.
Wiring is simplified with accessible relay terminals (C, NC, NO) through screw terminals.
Moreover, the inputs of the 8-channel 12V Relay Module are isolated, safeguarding delicate control circuitry from potential damage.
Compatible with a wide array of microcontrollers such as Arduino, AVR, PIC, and ARM, this module offers versatility and ease of integration.
By employing high-voltage relays, the risk of relay overheating is mitigated, as these relays regulate current consumption in accordance with voltage ratings, ensuring reliable operation.

Meaning of High level and Low-level
- High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
- Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
