Description
The module is an extension forArduinowith four relays that allow to switch off and on devices with power consumption up to 60 W (30 V / 2 A). Operation is facilitated by a library with intuitive documentation and numerous examples.
The subject of sale is 4 Relay Shield, Arduino moduleshould bepurchased separately.
Specification .
- 4 relays with parameters:
- Direct current: DC 30 V / 2 A
- Coil operating voltage: 5 V
- Coil current consumption: 35 mA (total approx. 140 mA)
- The voltage of the logical outputs: 5 V or 3.3 V (taken fromArduino)
- Outgoing TWI bus sockets (I2C)
- Arduino RESET button
- Arduino output pins - digital and analogue
- Possibility to impose further Shields
- The module uses Arduino outputs: 4, 7, 8, 12
