Set of 4 Control Relay Modules 5V / 12V – 1-Channel Module with Optocoupler and High/Low Trigger
This set of 4 relay modules (5V or 12V) provides stable control for AC and DC loads,
compatible with Raspberry Pi, Arduino, ARM, PIC, AVR, MCU, CNC projects, or custom systems.
Each module includes an optocoupler for isolation, NC (Normally Closed) and NO (Normally Open) contacts, as well as a jumper for selecting the trigger type (High/Low).
Main Features
Available in two variants: 5V relay module or 12V relay module
Maximum load: AC 250V/10A, DC 30V/10A
Optocoupler isolation: protects microcontrollers and reduces interference
Configurable trigger: jumper for High-Level or Low-Level Trigger
Fault-tolerant design: relay does not activate if the control line is broken
4 × 1-Channel Relay Module (5V or 12V — selectable)
Preinstalled screw terminals
Connection Guide
Connect Coil + and Coil – to the 5V or 12V power supply.
Connect the Trigger to a digital pin (GPIO).
Select High or Low Trigger mode using the jumper.
Use NC/C/NO terminals to control AC or DC loads.
Recommended Applications
Control lights, pumps, fans, electric locks, small motors, automation systems, IoT projects,
or prototyping solutions. The 5V model is ideal for microcontrollers, while the 12V model
suits automotive, industrial, or battery-powered projects.
