12V 10A 8-Channel OptoCoupler Relay Board Module are suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC. The relays used are rated up to 10A and have NO/NC contacts. Each channel has an LED indicator to show the relay is on. This 10A optocoupler relay module is used as industrial relay board 12V or as multi channel relay board for automation. Features: Using high-current relay, AC250V 10A DC30V 10A Contact some independent wiring, safe and reliable Standard interface, can be extended in a variety of development board With fixed screw holes for easy installation Suitable for a variety of platforms such as 51/AVR/AVR/ARM Connects directly to a micro-controller LED Indicator for each channel Specification: Input voltage: DC 12V Input Current: more than 300mA Connection : NC / COM / NO Relay parameters: The maximum you can control AC 250V, 10A DC30V 10A AC load, and maximum DC load. Module interface: VCC: 5V power supply connected to the positive GND: 5V power supply connected to the negative IN 1-IN 8: trigger signal, active low Relay outputs: A 12-line interface, the interface can be directly connected to all leads, user-friendly NO 1 – NO 8: normally open relay interfaces, relay before the vacant after the pull shorted with COM COM1 – COM8 Relay Common Interface NC1 – NC8: normally closed relay interface relay shorted with COM ago, after the pull-vacant Application: Support all MCU control PLC Control Switch control smart home, Hotel intelligent switch, Hotel intelligent electrical control, Intelligent greenhouses, Shopping smart switch, The company plant intelligent switch, Timer management cafes, Karaoke OK timing control, Physical networking, Industrial control equipment, Testing equipment power control, Street management, Intelligent management, Centralized power management Package Includes: 1 x 12V 8 channel relay board for Arduino Raspberry Pi
