16 Channel Relay Module 24V with Optocoupler Protection

The 16-Channel Relay Module with Optocoupler Protection is an industrial-grade control board designed for high-current switching applications in automation, robotics, and smart home systems. Operating at a stable 24V input, this module features an onboard LM2596 step-down voltage regulator to efficiently manage power distribution across all 16 channels. Each channel is equipped with complete optocoupler isolation to protect your sensitive microcontrollers (such as Arduino, ESP32, or Raspberry Pi) from electrical noise, electromagnetic interference, and high-voltage spikes.

This versatile relay board is ideal for PLC control, industrial automation, home automation, and DIY microcontroller projects. It supports both high and low-level trigger configurations, allowing seamless integration with various logic levels. The robust screw terminals ensure secure wiring for AC loads up to 250V 10A or DC loads up to 30V 10A, making it a reliable choice for controlling motors, solenoids, lights, and heaters in demanding environments.

Features:

• 16 Independent Channels: Control up to 16 separate electrical loads simultaneously.
• Optocoupler Isolation: Complete electrical isolation between control circuitry and high-power loads prevents damage to microcontrollers.
• Onboard LM2596 Regulator: High-efficiency step-down buck converter handles wide input voltages up to 24V.
• Flexible Triggering: Supports high-level or low-level trigger selection via jumpers.
• LED Status Indicators: Individual LEDs for each relay channel provide clear visual feedback on switching status.
• Heavy-Duty Switching: Rated for AC 250V/10A and DC 30V/10A loads.
