Raspberry Pi relay module expansion board phone control | Компьютеры и офис

• Supports Raspberry Pi A+/B+/2B/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

1. Raspberry Pi GPIO interface: for connecting Raspberry Pi
2. Relay screw terminal: for connecting target devices
3. Relays
4. Photocoupler: PC817
5. Relay indicator
   • LED on: relay NC is opened, NO is closed
   • LED off: relay NC is closed, NO is opened
6. Power indicator
7. Relay control jumper
   • 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

Note : the Pi in the photos is NOT included.
