Product description:
I、 size: 6.8cmx2.1cm
Ii.、 major chips: Ne555
Iii.、 working voltage: Dc 12 volt
Iv.、 characteristics:
- connecting power relays with delaying absorption. Specifically:: 12v, relays will not be absorbed immediately, the state of the relay output end is: Open and public disconnect, regular closure and public conduction Wait until 1-10s (Adjustable) Later, relay absorption and, at this point, the state of the relay output end is: Open and public access, frequent closure and public disconnect As long as the module is continuously electrical, this state will remain.
- adjustable time delay, (0-10 seconds)
- increasing the potentiometer can increase the delay time
- increasing capacitance c1 can increase the delay time
- with input power indicator
- a relay absorbing indicator
- controlled communication 220v/10a equipment. (Maximum control equipment 2000w)
- with relay continuation protection.
- time delay formula: T 1.1 rc. For example,: 100uf 100k t 1.1x100000 x 0.0001 11 second
【Application】
- delaying of vehicle-borne equipment, prevent cars from ing too much current to up vehicle-borne equipment.
- the need for sequential start-up, prevent multiple devices from simultaneously starting the current too big er.
