12V 1-Channel Relay Module - High Current AC/DC Control Board

Take control of your projects with this versatile 12V 1-Channel Relay Module. Engineered with a genuine, high-quality relay, this module provides reliable switching for a wide range of applications. It's perfect for hobbyists, engineers, and DIY enthusiasts looking to integrate robust control into their electronic systems.

Key Features:

• High Current Capacity: The normally open (NO) interface handles substantial loads, supporting up to AC 250V / 10A or DC 30V / 10A, making it suitable for controlling various power devices.
• Optocoupler Isolation: Features patch optocoupler isolation for strong driving capability and stable performance, ensuring your control signal is safely separated from the high-voltage load.
• Flexible Triggering: Supports both high-level and passive switch control (via jumper selection on the IN pin), offering adaptability for different microcontroller and sensor inputs.
• Compact Design: With dimensions of approximately 46mm x 21mm x 18mm (LWH), this module is small enough to fit into tight spaces without sacrificing functionality.
• Easy Integration: Clearly labeled input (VCC, GND, IN) and output (NO, COM, NC) interfaces simplify wiring and setup.

Technical Specifications:

• Module Operating Voltage: 12V DC
• Maximum Load (Normally Open):
  • AC: 250V / 10A
  • DC: 30V / 10A
• Trigger Current: $\ge$ 3mA
• Module Dimensions: Approx. 46mm x 21mm x 18mm (Length x Width x Height)

Interface Definitions:

Input Interface:

• VCC: Connect to the positive terminal of your 12V power supply.
• GND: Connect to the negative terminal of your power supply.
• IN: Connect to your signal's positive terminal (or connect to VCC via a switch for passive control).
  • Note: The signal's negative terminal should be connected to GND.

Relay Output Terminal:

• NO (Normally Open): This contact is open (disconnected from COM) when the relay is de-energized. It closes (connects to COM) when the relay is activated.
• COM (Common Pin): This is the common terminal for your load connection.
• NC (Normally Closed): This contact is closed (connected to COM) when the relay is de-energized. It opens (disconnects from COM) when the relay is activated.
