Features:
the working voltage: DC 4V ~ 6V
Working current: 80mA 
can control: AC Max 250V / 10A; DC Max 30V / 10A.
the trigger signal: high and low level signals; 0.5mA current.

High and low trigger mode of literacy:
Trigger control signal = VCC (ie voltage VCC): 1. The high trigger .
Control signal: 2. Low trigger  = GND ( ie voltage of 0V) is triggered .
