BESTEP 1-way electromagnetic relay module with dual optocoupler isolation supports high and low trigger 3.3V

Description

Product Overview

The BESTEP 1-Way Electromagnetic Relay Module is a versatile industrial-grade component designed to interface low-voltage logic circuits with high-power devices. Featuring dual optocoupler isolation, this module provides a robust physical barrier between your sensitive control circuit (such as an Arduino, ESP32, or Raspberry Pi) and the high-voltage load side, effectively eliminating electrical noise and protecting against voltage spikes.

This module supports both High-Level and Low-Level Trigger modes, making it compatible with virtually any microcontroller or digital logic system without the need for external level shifters. Whether you are controlling household appliances with a 5V Arduino or industrial equipment with a 3.3V ESP32, this module offers a safe and reliable switching solution.

Key Features

• Dual Optocoupler Isolation: Provides two layers of isolation for enhanced noise immunity and safety, preventing interference from inductive loads.

• Universal Trigger Modes: Supports both High Level (Active HIGH) and Low Level (Active LOW) input, selectable via onboard jumper.

• Wide Logic Compatibility: Operates reliably with control voltages from 3.3V to 5V, suitable for both 3.3V (ESP32, STM32) and 5V (Arduino) logic systems.

• High Power Switching: Capable of switching loads up to 10A @ 250V AC or 10A @ 30V DC.

• SPDT Contact Configuration: Features Common (COM), Normally Open (NO), and Normally Closed (NC) terminals for flexible wiring.

• Visual Indicators: Onboard LED provides real-time feedback on power status and relay activation.

• Standard Interface: Equipped with screw terminals for the high-voltage side and pin headers for the control side, facilitating easy integration.
