16CH 5V RELAY MODULE

The 16-Channel 5V Relay Module with LM2596S onboard power supply allows you to control 16 independent high-voltage/high-current loads using low-voltage microcontroller signals. Each relay features optocoupler isolation for safe separation of control and load circuits, with status LEDs for each channel.

Compatible with Arduino, AVR, PIC, ARM, MSP430, and any TTL-logic microcontroller. The onboard LM2596S buck converter means no external relay power supply is needed.

Features:

• 16 independent relay channels
• Trigger voltage: 5V DC (active low)
• Trigger current: 15–20mA per channel
• Switching capacity: 10A @ 250V AC / 10A @ 30V DC
• Optocoupler isolation on each channel
• Onboard LM2596S power supply — no external relay power required
• Status LED per relay channel
• Each relay has independent COM, NO, and NC terminals
• Compatible with Arduino, AVR, PIC, ARM, MSP430, TTL logic
