About us:
The module adopts high-performance timing CPU design, which is operate fast. It possesses of the power indicator LED
and switch trigger timing indication LEDs. The output can be connected to AC 250V 10A and DC 30V 10A,
and the max control equipment is up to 2200W. Has a very high cost performance, value for money.
Can be used with other circuits to provide a time delay for other appliances. Widely used with various electrical equipment,
especially for battery-powered control products. It can also be used in making hobby projects
Package including:
5pcs x NE555 Delay Module
Product specification:
The main chip: NE555.
Working voltage: 12 volts dc
Adjustable time : 0 to 10second
Over temperature protection: Automatically turn off the output after over temperature
Module size: 68mm * 21mm
Weight: 16g
Module performance and features:
1. Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power to the relay, the relay
will immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction;
wait until the delay is 1-10s (can be adjusted), the release of the relay and at this time, the state of the relay output is:
Normally open and public conduction, normally closed and public disconnect; this state will be maintained as long as the module is continuously powered.
2. The delay time is adjustable, (0 ~ 10 seconds)
3. Increase the potentiometer can increase the delay time
4. Increase the capacitance C1 can increase the delay time
5. Possess of input power indicator
6. Possess of relay pull-in indicator
7. can control the AC 220V/10A equipment. (Maximum control device 2000W) 8. Possess of relay freewheeling protection
9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
