3V 4 Channel Low Level Relay Module Without Light Coupling Overview
This 3V 4 Channel Low Level Relay Module Without Light Coupling provides four independent electromechanical relays triggered by low‐level signals. Designed for direct interfacing at 3V, it switches loads up to 10A (AC 250V/DC 30V) without optocoupler isolation, making it ideal for compact control projects.
Key Features of 3V 4 Channel Low Level Relay Module Without Light Coupling
- Four channels with low‐level trigger input (3mA trigger current)
- High load capacity: AC 250V @ 10A or DC 30V @ 10A per channel
- Configurable high/low level triggering via onboard jumper
- Fault‐tolerant design ensures relays remain off if control line is interrupted
- LED indicators: green for power, red for relay activation status
- Direct IN, NO, NC, COM terminals for straightforward wiring
- Fast shipping across India from Zbotic’s inventory
Applications and Use Cases
- Home automation: switch lights, fans or appliances from microcontrollers
- Robotics: control DC motors and actuators with 3V logic boards
- Industrial control: manage valves or indicators in small machinery
- Alarm and security systems: drive sirens, door locks or warning lights
- Automotive prototypes: toggle 12V accessories via low‐voltage control
How to Use 3V 4 Channel Low Level Relay Module Without Light Coupling
Connect a stable 3V supply to VCC (DC+) and GND (DC–), set the jumper for high or low level triggering, then wire your control signals to the IN pins. Attach your load between COM and NO (or NC for default-on operation). When an IN pin is driven to the trigger level, its corresponding relay closes, allowing current to flow through the switched circuit.

Frequently Asked Questions
Can I drive this module directly from a 3.3V microcontroller?
Yes. With a trigger current of just 3mA and a 3V working voltage, it’s fully compatible with 3.3V logic devices like Raspberry Pi, ESP32, Arduino Pro Mini 3.3V, and similar boards.
How do I switch between high‐level and low‐level trigger modes?
Use the onboard jumper provided. Place it on “L” for low‐level activation (IN goes low to trigger) or on “H” for high‐level activation (IN goes high to trigger).
What types of loads can this relay handle safely?
Each relay channel can switch up to AC 250V at 10A or DC 30V at 10A. It’s suitable for lamps, small motors, heaters, pumps, and other devices within those voltage and current ratings.
