Summary

The HiLetgo 4 Relays Shield provides four independent relay channels for switching high-power loads, with individual enable control and status monitoring.

Description

This relay shield offers four optically isolated relay channels capable of switching AC/DC loads up to 250VAC/30VDC at 10A. Each relay features independent control with enable/disable functionality and initial state configuration. The shield includes LED status indicators for each relay channel and is designed for home automation, industrial control, and high-power switching applications.
