Mạch hẹn giờ điện DC 5V-30V Micro USB có thể điều chỉnh tăng hiệu điệu thế lên 12V 24V - intl

Module features:

1. Working voltage: Wide-voltage 5--30V between any voltage, MicroUSB power connector and two solder terminals

2. Operating mode: to the module power output of the module state: 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 trigger button and instantly, the relay and, working lights, this time, 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 opens after the bell, then relay back to the state before the trigger.

3. The time can be adjusted via a potentiometer, default 0-24 seconds. If you need more time, more replaceable capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example: 1M resistor capacitor 22uf then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds.

4. With a relay indicator.

5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (direct current) following loads.

6. Has freewheeling protection relay.

7. signal terminal block is designed with a pull and a 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 trigger or enhance the stability of end to interference, regardless of this module is the electromagnetic interference environment, or instantly through 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. The vehicle-mounted device is turned on delay, to prevent excessive current when the car ignition burned-board equipment.

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