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.
Module performance and features:
1. The relay time delay and power supply is connected: for 12 v power supply to the relay, relay not immediately and absorption, relay the output status to: normally open and public disconnect, normally closed and public conduction;Wait for delay 1-10 s (adjustable), relay and absorption, at this point, the relay outputs status to: normally open and public conduction, normally closed and public disconnected;As long as the module power continuously, this state will remain.
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

Già usato in passato, ne tengo sempre qualche pezzo in magazzino e dovendo fare un lavoro ne ho cquistati altri ma ho riscontrato il problema del non ritegno del relè allo scadere del tempo, ho fatto il reso di questo acquisto ma ne avevo in magazzino 5 pezzi il cui tempo limite di reso era scaduto. Ho trovato e risolto il problema sostituendo una resistenza con una di altro valore (270ohm) Se qualcuno si è trovato nelle stesse condizioni puo evitare di cestinare i timer che gli sono rimasti. Ritengo che il problema derivi dall'assenza di una tensione di riferimento precisa per il 555, magari bastava uno zener o il classico 78xx
