20-Channel Relay Module PCB Design for Industrial Control Applications

This project involves the design and development of a custom 20-channel relay control PCB module intended for reliable switching of multiple loads in industrial or automation systems.

The goal is to create a robust and well-structured PCB that integrates 20 relay channels with proper driver circuitry, protection mechanisms, and clear interface headers for external control via microcontroller or control system.

The design should prioritize stability, safety, and ease of integration into existing automation setups.
