1 Channel 5V Relay Module without Optocoupler
Description:
1-Channel 5V Relay Module Without Optocoupler is a compact and efficient relay module designed to control high-voltage electrical devices with a low-voltage microcontroller or automation system. This module provides a simple way to interface your microcontroller (like Arduino, Raspberry Pi, or others) with devices that require higher voltage or current to operate, such as lights, motors, or household appliances. However, unlike relay modules with optocouplers, this version does not offer electrical isolation between the control and relay sides, which makes it best suited for applications where the potential for electrical noise or damage to sensitive components is low. This module is equipped with one relay, which is ideal for simple applications where only a single device or circuit needs to be controlled. Whether for controlling lights, fans, or other appliances, this single-channel relay can handle the task without unnecessary complexity.
Features:
1. Single Relay Channel (1-Channel)
2. 5V DC Power Supply
3. Simple Active-Low Control
4. No Electrical Isolation (No Optocoupler)
5. High-Voltage and High-Current Switching
6. LED Indicator for Relay Status
7. Compact and Easy to Integrate
8. Low-Cost Solution
9. Ideal for Simple DIY and Automation Projects
10. No Protection Against Inductive Loads
