1 Channel Infrared Remote Control Relay Module

1 Channel Infrared Remote Control Relay Module provides a convenient and safe way to wirelessly control high-voltage appliances or other electrical devices using a standard infrared (IR) remote. This module integrates an IR receiver and a robust relay on a single board, allowing you to instantly switch devices like lights, fans, or motors on and off from a distance. Its straightforward design accepts a wide range of DC input voltages and features clear terminal block connections, making it incredibly easy to integrate into existing home automation, robotics, or DIY security systems. Eliminate the need for complex wiring and enjoy the simplicity of reliable remote power control with this versatile module.

Key Features:

• IR Remote Control: Activate the relay wirelessly using the included small IR remote, providing a clear line-of-sight range typically up to 8 meters.
• Single Channel Relay: Features one powerful channel capable of switching high AC or DC current loads, perfect for controlling a single appliance or circuit.
• Jumper Selectable Mode: Easily set the relay to either momentary (press-and-hold) or latching (toggle on/off) mode using an onboard jumper cap.
• Indicator LEDs: Onboard LEDs provide visual confirmation for both power status and relay activation, simplifying troubleshooting.
• Optocoupler Isolation: Uses an optocoupler to isolate the control circuit from the relay coil, protecting sensitive control components from voltage spikes.
• Screw Terminal Connections: Clearly labeled, robust screw terminals secure power input, load connections (NO/NC/COM), and signal pins.

Technical Specifications:

• Operating Voltage (VCC): DC 5V, 12V, or 24V (Specific to the model variant)
• Standby Current: ~7 mA
• Max Relay Current (Coil Active): ~50 mA
• Load Voltage (AC): Max 250V AC
• Load Current (AC): Max 10A
• Load Voltage (DC): Max 30V DC
• Load Current (DC): Max 10A
• IR Frequency: 38 kHz (Standard IR Remote)

Mechanical Specifications:

• Relay Type: Single Pole Double Throw (SPDT) with Normally Open (NO), Normally Closed (NC), and Common (COM) terminals.
• Mounting: Two fixed screw holes provided for easy mounting onto chassis or enclosures.
• Heat Dissipation: Passive, via the PCB and ambient air.

Dimensions:

• Length: ~50 mm
• Width: ~20 mm
• Height: ~18 mm

Pinout and Wiring:

• VCC: Connect to the positive power supply (e.g., 5V, 12V, or 24V DC).
• GND: Connect to the circuit ground.
• COM: Connect the power source or load line that you want to switch.
• NO (Normally Open): Connect the load side. The connection closes when the relay is activated.
• NC (Normally Closed): Connect the load side. The connection opens when the relay is activated.
• Wiring Note: Always connect the power source to VCC and GND. To switch a lightbulb, connect the live wire to COM, and the lightbulb’s wire to NO. The circuit completes when you press the remote button.
