The 4 Channel Relay Module is a convenient board which can be used to control high voltage, high current load such as motor, solenoid valves, lamps and AC load. It is designed to interface with microcontroller such as Arduino, PIC and etc. The relays terminal (COM, NO and NC) is being brought out with screw terminal. It also comes with a LED to indicate the status of relay.

Specification:

• Digital output controllable
• Compatible with any 5V microcontroller such as Arduino.
• Rated through-current: 10A (NO) 5A (NC)
• Control signal: TTL level
• Max. switching voltage 250VAC/30VDC
• Max. switching current 10A
• Size: 76mm x 56mm x 17mm

• There are four fixed screw holes at each corner of the board, easy for install and fix. The diameter of the hole is 3.1mm
• High quality Songle relay is used with single pole double throw, a common terminal, a normally open terminal, and a normally closed terminal
• Optical coupling isolation, good anti-interference.
• Closed at low level with indicator on, released at high level with indicator off
• VCC is system power source, and JD_VCC is relay power source. Ship 5V relay by default. Plug jumper cap to use
• The maximum output of the relay: DC 30V/10A, AC 250V/10A
