MicroUSB 5.0V power supply with an input port, easy to use.
5 ~ 30V wide supply voltage.
External signaltrigger and keytriggerin two ways.
With a relay indicator.
Anti-interference ability, the relay at various interference will not misoperation, suitable for industrial control.
1. Working voltage: wide voltage 5 ~ 30V, two power supply interface
2. Operating mode:
the initial state, module outputs: normally open (NO) and the common terminal (COM) is disconnected,
normally closed (NC) and the common terminal (COM) connected.
Providing a low pulse signal, or touch trigger key, relay and indicator lights,
the output of the state: normally open (NO) and Common (COM) connected,
normally closed (NC) and the common terminal (COM) is disconnected.
After 0-24 seconds (this time can be adjusted according to your needs) relay off,
back to the state before the trigger.
3. The length of timing adjustment by potentiometer, default 0-24 seconds.
If you need more time, you can replace the larger capacitor (C2) or potentiometer.
Delay time T = 1.1RC. For example: 22uf capacitor and resistor 1M,
then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds.
4. With a relay indicator.
5. The module can control: 10A / 250VAC, 10A / 30VDC load.
6. The relay has a freewheeling protection.
7. Trigger signal input terminal is designed with a pull and filter circuit,
enhanced anti-jamming capability, suitable for industrial control.
Many manufacturers add the optocoupler isolation,
but there is no separation between moduleâ€™s ground and signalâ€™s ground,
would not achieve the interference effect.
After the test found that only enhance the stability of the signal input port to interference,
