Type A: ( 0.2 second ~ 45 seconds ) or x256 = (40 seconds ~ 200 minutes) Type B: ( 1 second ~ 9 minutess ) or x256 = (256 seconds ~ 38 hours) Module parameters: Input Voltage: DC 3~27V; Drive current: 1500mA; Maximum quiescent current: 3V -- 0.22mA, 5V -- 0.45mA,12V -- 1.6mA,24V -- 4.4mA;The longer the time runs out, the quiescent current is smaller. Output high and open the two states, the output high drive current 1500mA. PCB Size: 13.5 * 21 mm It can be adjusted between a delay time of 0.2 second ~ 45 seconds (Range 1)¼ or 40 seconds ~ 200 minutes (Range 2) for type A ( for type B, 1 second ~ 9 minutess or x256 = 256 seconds ~ 38 hours) ( for type C, 22 seconds ~ 110 minutess or x256 = 93 minutes ~ 469 hours) Pin Definitions: Vcc: Power Input (+), Vo: output, Vi: Re-set (connect power + to reset) (reset at high level. after reset, user can set output level at Vo), Gnd: negative (-) of power supply, Package Included: 1x Module
