Beschreibung
The RPi Relay Board gives your Pi the abliity to control high voltage/high current devices, easliy makes normal home appliances become intelligent.
RPi Relay Board Features
- Supports Raspberry Pi A+/B+/2B/3B/3B+
- High quality relays, loads up to 250VAC/5A, 30VDC/5A
- Photo coupling isolation, prevent interference from high voltage circuit
- Onboard LEDs for indicating relays status
- Relay control jumper, allows to control the relays by custom pins other than the default pins
- Comes with development resources, including examples in wiringPi, WebioPi, shell, python, and bcm2835
Schematic
- Raspberry Pi GPIO interface: for connecting Raspberry Pi
- Relay screw terminal: for connecting target devices
- Relays
- Photocoupler: PC817
- Relay indicator
- LED on: relay NC is opened, NO is closed
- LED off: relay NC is closed, NO is opened
- short the jumper: control the relays by default I/Os used in the example code
- open the jumper: control the relays by custom I/Os through jumper wires
