1 Output Relay Module Works on 5V Signal

This relay module features SMD optocoupler isolation for improved signal protection and stability. It supports high-level or low-level triggering, selectable via an onboard jumper. Designed with fault-tolerant protection, the relay will remain inactive if the control signal is disconnected, enhancing operational safety.

The module includes a green power indicator LED and a red relay status LED for easy monitoring. All connections are made through screw terminal blocks, ensuring secure and straightforward wiring.
