hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirstock per 7 des = 10 pcs

Wide Voltage 5V-30V Trigger Delay Relay Module Timer Module Delayed On-Delay
Switch Button

Module Highlights:

Time can be adjusted by potentiometer, meeting your most occasions .

With MicroUSB 5.0V power supply input, easy to use.

5--30V wide supply voltage.

External trigger and on-board key trigger two ways.

With relay pull indicator.

Anti-interference ability, all kinds of interference relay will not malfunction,
suitable for industrial control.



Module Features:

1. Operating voltage: Wide-voltage 5--30V between any voltage, MicroUSB and
solder terminals two power supply interfaces

2. Working mode: to the module power 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.

(NO) and common (COM) are turned on when the external trigger terminal (TRIG)
gives a low pulse signal, or the trigger key is touched instantaneously, the
relay is sucked and the operation indicator is on. At this time, the state of
the relay output terminal is: Normally closed (NC) and common (COM)
disconnected, after 0-24 seconds (this time can be adjusted according to your
needs) after the relay disconnect, then the relay back to the state before the
trigger.

3 . Time can be adjusted by potentiometer, default 0-24 seconds. If a longer
time is required, replace the larger capacitor (C2) or the potentiometer. Delay
time formula: T = 1.1RC. For example: capacitor 22uf resistance 1M then T = 1.1
* 0.000022 * 1000000 = 24.2 seconds.

4. With the relay pull light.

5. Module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) the following load.

6. With relay freewheeling protection.

7. Module signal side design of the pull-up and filter circuit,
anti-interference a
