2.4GHz Wireless Remote 7 Channel Driver Module


General Description

SL878X7, a 2.4GHz ISM band wireless remote high current Darlington arrays, contains seven open collector Darlington pairs with common emitters. Each channel is rated at 500mA and aBluetooth Smart to withstand peak currents of 600mA. Together with SWiRAS gateway and application software, via local network and internet, SL878-x7 can be easily controlled by a SmartPhone (including iPhone, Android Phone and all the other smart phones) or PC sending specified commands. Thus, this versatile device is useful for driving a wide range of loads including solenoids, relays DC motors, LED displays, filament lamps and high power buffers in the remote site.
