5V 8 Channel Relay Module Board for Arduino PIC AVR MCU DSP ARM
This item is a 5V 8-Channel Relay interface board,It can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on.
8-Channel Relay interface board.
Each one needs 15-20mA Driver Current.
Equiped with high-current relay : DC30V 10A AC250V 10A.
Each relay has normally open and normally closed contact.
The 8 channels are optically isolated, safe, reliable, anti-interference.
Can be selected by jumper relay and TTL or ground.
With power indicator,8-way road has a status indicator.
With a relay coil to absorb the diode protection.
