3-Channel Power Relay Module HAT Expansion Board 40-Pin GPIO Interface 5A 250VAC/5A 30V DC Optocoupler Isolation Relay Indicator and Jumper For Raspberry Pi 4B/3B+/3B/2B/A+/B+
- Designed around a Raspberry Pi 40-pin GPIO interface and compatible with Raspberry Pi 4B, 3B+, 3B, 2B, A+, and B+ boards.
- Three-channel relay expansion board provides three relay outputs for controlling connected loads through a Raspberry Pi setup.
- Each relay supports loads up to 5A at 250VAC or 5A at 30V DC, as specified for the module.
- Optocoupler isolation helps avoid interference from high-voltage circuits between the control side and relay circuits.
- Built-in relay indicator lights make it easier to view the working status of each relay during operation.
- Relay selection jumper caps allow switching between Raspberry Pi control and other pins for relay control.
- The Raspberry Pi's weak-current IO output can control the switching of stronger currents through this relay module.
- Combined with Raspberry Pi network capabilities, the module supports remote control of home appliances in smart-home applications.

Product Description:
Three-channel power relay HAT expansion board designed for Raspberry Pi boards with a 40-pin GPIO interface. It enables Raspberry Pi control of connected electrical loads and is suitable for smart home and other high-current control applications.
Core Selling Points:
High-quality relays support connected loads up to 5A at 250VAC or 5A at 30V DC. Optocoupler isolation helps reduce interference from high-voltage circuits. Relay indicator lights provide a clear view of operating status, while the relay selection jumper cap supports control switching between Raspberry Pi and other pins.
Technical Specifications:
Product type: Three-channel (3-CH) power relay module. Interface: Raspberry Pi 40-pin GPIO. Load capacity: 5A 250VAC or 5A 30V DC. Isolation: Optocoupler. Status feedback: Relay indicator lights. Control selection: Relay selection jumper cap. Compatible Raspberry Pi models: 4B, 3B+, 3B, 2B, A+, and B+.
Before Purchase:
This board is compatible only with 40-pin Raspberry Pi boards and is not compatible with 26-pin connectors. Confirm that your Raspberry Pi model and GPIO interface match the listed compatibility requirements before purchase. Connected loads must remain within the stated 5A 250VAC or 5A 30V DC capacity.
