US SHIP 5pcs DC 12V Delay Relay Shield NE555 Timer Switch Adjustable Module

Item number:1936
Product description:
Module based on : NE555 chip
Delay module : Delay connect module(Time delay on)
Input voltage : DC12V
Control voltage : AC 0 – 250V/max. 10A, DC 0 – 30V/max. 10A
The operating voltage : 12V DC
Max. load : 2200W
Size : Approx 6 x 2cm
Feature :
Power relay delay pull. Specifically : 12v power supply to the relay, the relay will not immediately sucked and status relay outputs are: normally open disconnected public, normally closed and public conduction; wait until the delay 1-10s (adjustable), the relay suction and, this time, the relay output status is: normally open and public conduction, normally closed and public disconnected; as long as Uninterrupted power module, this state will remain
The delay time is adjustable, (0 to 10 seconds)
Increasing the potential can increase the delay time
Increasing the capacitor C1 can increase the delay time
With input power indicator
With relay indicator
Can control AC 220V / 10A about equipment (Maximum control equipment 2000W)
With freewheeling protection relay
The delay time formula : T = 1.1RC. For example : a resistor capacitor 100uf 100K T = 1.1 x 100000 x 0.0001 = 11 seconds
Package included:
5 x Delay Relay Modules
