Quick Overview
The DIYables 4-channel 5V relay module is a convenient way to control multiple loads from a microcontroller. It’s useful for home automation, control panels, and projects where you want to switch devices using clean, screw-terminal wiring.
This package contains a 5V 4-channel relay module. Each relay supports Normally Open (NO) and Normally Closed (NC) wiring and includes optocoupler isolation. Trigger mode (high-level or low-level) can be selected via jumper, making it adaptable to different controller logic.
Key Features
- 4 Independent Relays — Four channels for switching four loads independently
- Screw Terminals — Easy and secure wiring on input and output sides
- NO/NC Contacts — Normally Open and Normally Closed contacts per relay
- Optocoupler Isolation — Isolates control signals from switching side for safety
- Selectable Trigger Mode — High-level or low-level trigger via jumper
- Wide MCU Compatibility — Works with 3.3V and 5V microcontrollers
- Load Switching — Control AC/DC devices like lights, pumps, fans, appliances
- Tutorial Support — Comprehensive guides for all platforms
- Home Automation Ready — Perfect for smart home and control panel projects
- Robust Design — Reliable relay switching for multiple loads
