Relay Module 5V 1-Channel Optocoupler Isolated 10A 250V AC High/Low Level Trigger for Arduino Raspberry Pi ESP32

Overview:

This high-performance 5V 1-channel relay module features SMD optocoupler isolation for superior stability, strong driving capability, and electrical safety for your microcontroller. It handles up to 10A switching loads and supports High and Low level triggering via an onboard jumper.

Key Features:

• Optocoupler Isolation: Uses SMD optocouplers to isolate sensitive control electronics from high-power loads.

• Dual Trigger Modes: Easily select High-level or Low-level control via an onboard jumper cap.

• Fault-Tolerant Design: The relay will not activate if the control signal wire is disconnected or broken.

• LED Status Indicators:

  • Green LED: Power indicator

  • Red LED: Relay state indicator

• User-Friendly Interface: Direct screw-terminal connections for easy installation without soldering.

Specifications:
