Overview:
This 5V 1-Channel High-Level Trigger Relay Module is an essential component for microcontroller development, robotics, and smart home appliance control. Designed with transistor amplification and active pull-down logic, it delivers reliable load switching while protecting your control board logic pins.
Key Features:
- High-Level Trigger Logic: Compatible with 5V to 12V TTL logic signals.
- Enhanced Transistor Drive: Transistor circuit increases coil driving efficiency while keeping control inputs at high impedance.
- Floating Pin Safety: Integrated pull-down circuit ensures the relay remains stably OFF if the control wire becomes disconnected.
- Status Monitoring: Built-in LED indicators show board power status and active relay coil operation.
- Versatile Load Control: Safely switches AC loads up to 220V AC or standard DC signals.
Specifications:
- Relay Operating Voltage: 5V DC
- Control Signal Voltage: 5V – 12V TTL (High-Level Trigger)
- Contacts: Normally Open (NO) / Normally Closed (NC) / Common (COM)
- Application: Microcontroller development, home automation, load switching
