DIYables 4 Channel 5V Relay Module for Arduino ESP32 Raspberry Pi, 2 Pack

Key features

• 4-CHANNEL INDEPENDENT RELAY CONTROL: Each of the 4 relay channels operates independently, supporting AC 250V/10A and DC 30V/10A loads, perfect for home automation, robotics, and industrial control
• OPTOCOUPLER ISOLATION PROTECTION: Each channel uses an optocoupler to electrically isolate your microcontroller from high-power loads, preventing voltage spikes and interference from reaching your control board
• SELECTABLE HIGH AND LOW LEVEL TRIGGER: Onboard jumper selects HIGH or LOW level triggering to match your microcontroller logic; compatible with both 3.3V and 5V control signals
• FLEXIBLE NO NC COM OUTPUTS: Each relay provides Normally Open (NO), Normally Closed (NC), and Common (COM) terminals for versatile switching of AC or DC devices in your automation circuits
• 2 PACK VALUE SET: Includes 2 identical 4-channel relay modules; great for multi-zone control, redundant switching setups, or having a backup for your automation and robotics projects
