5V~30V Micro USB Power Relay Timer Control Module Trigger Delay Switch Description:
- By adjusting the potentiometer can set the length of time.
- 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 - 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 module’s ground and
- signal’s ground, would not achieve the interference effect. After the test found that
- only enhance the stability of the signal input port to interference, regardless of this
- module is under electromagnetic interference environment, or in the power-up and
- power-down moment, the relay will not produce misoperation.
- 8. Dimensions(L * W * H): Approx. 5.4 * 2 * 1.8cm / 2.13x0.79x0.71inch
- Applications:
- 1. Burglar, alarm, building delay switch, sound and light control light switch.
- 2. Delay powered vehicle equipment, to prevent large currents generated as the
- car starts burning vehicle equipment.
- 3. Prevent simultaneous launch multiple devices cause burning appliances or fail
- to start.
