Raspberry Pi Relais Board

Description Raspberry Pi Relais Board

The Raspberry Pi Relais Board is a powerful extension for you Raspberry Pi. It makes it possible to operate devices with high voltage or current. With this board transform your simple home appliances into smart devices. It board is equipped with a standard 40PIN GPIO expansion header that is compatible with the Raspberry Pi-series. It features high-quality relays that can handle loads up to 5A at 250V AC or 5A at 30V DC. Thanks to the photocoupler isolation it is board protected against interference from high voltages. It also has LED indicators for relay status and a jumper for relay control. This allows you to control the relays with custom pins, not just the standard pins. It board comes with development resources. Including examples in wiringPi, WebioPi, shell, python and bcm2835. Each of the three screw terminals on the board has three pins for connecting external circuits. These terminals are low active, meaning that when the Raspberry Pi outputs a low level, the corresponding LED lights up and the relay switches the external circuits on or off.

Features Raspberry Pi Relais Board

• Standard 40PIN GPIO expansion header, supports the Raspberry Pi-series.

• High-quality relays with a load capacity of up to 5A 250V AC or 5A 30V DC.

• Photo-coupling isolation for protection against high voltage interference.

• LED indicators for the status of each relay.

• Relay control jumper, for control with custom pins.

• Includes development resources with examples in several programming languages.

• Three screw terminals with three pins each for external connections.

• Low active terminals for easy integration with external circuits.

Connection method

1. Raspberry Pi GPIO interface: for connecting Raspberry Pi.
2. Relay screw terminal: for connecting target devices.
3. Relay.
4. Photo link: PC817.
5. Relay indicator.

• LED on: relay NC is open, NO is closed.
• LED off: relay NC is closed, NO is open.

6. Power indicator.
7. Jumper for relay control.

• short the jumper: operate the relays standard I / Os used in the sample code.
• open the jumper: control the relays via custom I / Os via jumper wires.
