Multi-channel opto-isolated relay control module with switchable high/low trigger, available in 1/2/4/8/16 channels and 5V/12V/24V options, safely driving 220V AC loads for Arduino, smart home and industrial control projects.

Description

1/2/4/8/16 Channel Relay Control Module Product Description

Product Overview

Our multi-channel relay module is a universal isolated switching control board designed for microcontroller DIY projects, home automation, industrial circuit control and appliance transformation. Available in 1/2/4/8/16 channel options with 5V/12V/24V three voltage versions, it supports both high-level and low-level trigger modes, enabling safe control of DC and 220V AC high-power loads with reliable optocoupler isolation design.

Core Features

Dual Isolation Safety Design
Built-in isolation slots separating the signal control area and high-voltage load area, fully compliant with international electrical safety standards. Optocoupler isolation effectively blocks interference between MCU signal circuits and AC power loads, protecting your Arduino, Raspberry Pi, STM32 and other main control boards from surge damage.
Genuine Standard Relay with Large Load Capacity
Equipped with original JQC-3FF-S-Z relays, each channel supports max 10A 250VAC / 15A 125VAC load. Every relay has 1 Normally Open (NO) + 1 Normally Closed (NC) contact, flexible for various switching logic requirements.
Dual Trigger Modes Switchable
Comes with a solder jumper cap to switch between low-level trigger (0-1.2V signal) and high-level trigger, perfectly compatible with all mainstream single-chip microcontrollers. Trigger voltage range: 0-4V, trigger current only 3mA, low power consumption and sensitive response.
Dual LED Status Indicators
Independent red power indicator + green relay action indicator. The green light lights up when the relay is pulled in, turns off when disconnected, allowing you to quickly check the working status at a glance without measuring equipment.
Low Power Consumption Circuit
Static current: 5.5mA; Operating current: 42mA per channel. Ultra-low standby power will not cause extra power loss for your control system, suitable for long-term uninterrupted operation equipment.
User-Friendly KF301 Terminal Block
Blue standard KF301 screw terminals for both signal input and load output ports, firm wiring, convenient plug-and-play, no loose wires during long-time operation.
Multiple Specifications for All Scenarios
Complete product lineup: 1CH / 2CH / 4CH / 8CH / 16CH; Working voltage optional: DC 5V / 12V / 24V. Different sizes and weights to match small DIY prototypes, multi-way centralized control cabinets and intelligent home central control systems.

Wiring Guide

1. Control Signal Port (VCC/GND/IN)

VCC: Connect matching DC working voltage (5V/12V/24V) consistent with relay version
GND: Common ground with your microcontroller
IN: Trigger signal input pin, control relay on/off via high/low level signal

2. Load Output Port (COM / NO / NC)

COM: Relay common terminal
NO (Normally Open): Disconnected when power off, connected when relay triggered
NC (Normally Closed): Connected when power off, disconnected when relay triggered

Wide Application Scenarios

Microcontroller Development: Arduino, Raspberry Pi, ESP32, STM32 experimental control
Smart Home Automation: Light, curtain, water pump, air conditioner power switching
Industrial Equipment: Motor, solenoid valve, small machine tool circuit control
DIY Electronic Projects: Intelligent car, greenhouse automatic control, battery charge management
