Tajmer odnsono vremensko rele koje se ISKLJUCUJE u intervalu od 0 do 24 sekunde.
Modul ima ulaz za okidanje koji kada se dovede na nizak nivo (ili se pritisne traster) pali rele koji ostaje privucen do 24 sekunde (kako se nasteluje plavim trimerom) nakon cega se iskljucuje i ceka sledeci signal za okidanje.

Duzina zadrske se menja trimerom u zavisnosti od potrebe.
Moze da se napaja USB kablom sa racunara ili obicnoh punjaca za mobilni koji ima Micro USB prikljucak.

Ulazni napon: 6-30V ili USB napajanje 5V
Vremenska zadrska: 0 to 24 sekunde
Maksimalno opterecenje: 10A
Led dioda signalizirajau ukljuceno rele.

1. Working voltage: Wide-voltage 5-30V, two power supply terminal or the interface MicroUSB KF301

2. Operating mode: power supply, the output of the module status: normally open (NO) and the common terminal (COM) open, normally closed (NC) and the common terminal (COM) is turned on.

Originating outside the contact (TRIG) to a low pulse signal, or touch button to trigger instant, and relay, work lights, and the status of the relay output: normally open (NO) and the common terminal (COM) is turned on, normally closed (NC) and the common terminal (COM) is disconnected after 0-24 seconds (this time can be adjusted according to your needs) relay is switched off after the bell, then relay back to the state before the trigger.

3. The time can be adjusted by potentiometer, default 0-24 seconds. If you need more time, may be replaced by the larger capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example: Capacitor 22uf resistance 1M T = 1.1 * 0.000022 * 1000000 = 24.2 seconds.

4. With relay indicator.

5. Control: 10A 250VAC (AC), 10A 30VDC (DC) or less load.

6. Has freewheeling protection relay.

7. signal terminal block has a pull-up and design of the filter circuit, anti-jamming capability, suitable for industrial control. Many manufacturers have added optocoupler isolation, but with the trigger signal to the module and not isolation, would not achieve the interference effect. After the test was found to improve the stability of the trigger end to interference, whether in this module under electromagnetic interference environment, or through instant power module, the relay will not malfunction.

8. Size: 5.4 * 1.9 * 1.8cm (L * W * H)

9. Weight: 16g

Applications:

1. The anti-theft alarm delay, building sound and light control lamp switch.

2. Delay-vehicle device is turned on, when the car ignition to prevent excessive current burn-vehicle equipment.

3. The need to have in order to start the occasion, prevent multiple devices simultaneously starting current is too large burning appliances.
