PRODUCT INTRODUCTION
- 1. Standard Shield interfaces and shape
- 2. Can continue to stack other expansion boards
- 3. 3 M3 screw positioning holes for easy installation
- 4. High Drive (5V or 3.3V) normally open contact closure
- 5. Onboard relay indicator (red)
- Special Note: When using the UNO board connected to it, because UNO USB interface is extremely high, should avoid green terminals are shorted its shell.
- Relay Shield Interface:
- Relay: sky- 5V DC relay , model HJR-4102-L-5V, which Relay1 behalf of the 1st relay , the other and so on.
- Power Interface : 5V DC power interface
- Indicator: four lights are red when the relay is driven high , the corresponding indicator will light up .
- Relay Terminals: Terminal high-power , high-current high voltage can be connected to the device . The 1st foot ( i.e. NOx) is a normally open pin , NCx pin is normally closed , COMx is common, i.e., when the relay is not driven , NOx and COMx open between two pins , NCx and COMx connection ; When the relay (x) control signal pin is high drive relays , NOx and COMx connection open between NCx and COMx.
