Original Arduino relay shieldThe Arduino 4 Relays Shield allows your Arduino driving high power loads that cannot be controlled directly by Arduino's digital pins. The Shield features four relays, each relay with 2 pole changeover contacts (NO and NC). Four LEDs indicate the on/off state of each relay.
The relays are controlled by the following Arduino board pins:
Relay 1 = Arduino pin 4
Relay 2 = Arduino pin 7
Relay 3 = Arduino pin 8
Relay 4 = Arduino pin 12
The shield features several TinkerKit input/output and communication interfaces. Connecting TinkerKit modules can simplify the creation of a project or a prototype.The on-board connectors are :
2 TinkerKit Inputs: IN2 and IN3 (in white), these connectors are routed to the Arduino A2 and A3 analog input pins.
2 TinkerKit Outputs: OUT5 and OUT6 (in orange), these connectors are routed to the Arduino PWM outputs on pins 5 and 6.
2 TinkerKit TWI: these connectors (4-pin in white) are routed on the Arduino TWI interface. Both connect to the same TWI interface to allow you to create a chain of TWI devices.
- Operating Voltage: 5V
- Coil current consumption: 140 mA (with all releays on, about 35 mA each)
- Single pole chargeover contact maximum current: @ 30 V DC 2A
- Maximum load voltage: 48 V
- Maximum switching capacity: 60 W
