usb serial control device to control the power centralized intelligent management 8 channel 30A power relay module

1,Onboard SquareUSBInterface , using importsParallelFIFOBi-directional data transferUSBControl chip, stable connection ;
2,Use special relay driver chipULN2803Relay more stable ;
3Using original song musicSLAPower relays , can withstand30AThe maximum power ;
4Use wide spacing9.5mmBarrier Terminal Block Terminal reliable security ;
5, Power input has a high power step-down circuit , you can use5-30VWide input voltage for equipment commonly used supply voltage ;
6, Product use PC software control , withUSBCable can control each relay -off and delay ,Even if the computer is turned off orUSBUnplug from the computer , you can keep the same set state relay ;
7Sided are large copper , the bottom surface and the bare copper plus tin , then more reliable power load between relay and terminals ;
8, Each relay with normally open , common, normally closed terminal

Second, the module application :

Home intelligent switch control, intelligent switch hotel , hotel intelligent electrical control , intelligent greenhouses , shopping malls intelligent switch , the company plant intelligent switching , timing of management of Internet cafes , karaokeOKTiming control , physical networking , industrial control equipment , testing equipment power control , street management, intelligent management, centralized power management.

Fourth, the product interface description :

1,+ 5VversusGNDEnd for receiving5VDC power input voltage range :5-6V;
2,7-30VversusGNDEnd for receiving7-30VBetween the DC power input ;
3,USBDirect interface with a computerUSBInterface ;
4Relay terminals :
     COM /Common : Common relay
     NO /Normally open : normally open relay when the relay pulls in, the common terminal and the normally start turning , no pulls in, the common terminal and the normally closed terminal is connected;
     NC /NC end : the relay normally closed terminal , relay no pulls in, the common terminal and the normally closed terminal connected.

V. Product Description

1, Before use of the module is determined to provide an input voltage is how much , if it is5VPlease contact5VversusGNDEnd , if it is7-30VPlease contact7-30VversusGNDEnd ,
