XY018 Adjustable Timer Delay Trigger ON OFF Switch Relay Module 5-30V

XY018 Adjustable Timer Delay Trigger ON OFF Switch Relay Module 5-30V

Features:

Rotating potentiometer can set the length of time.

MicroUSB 5.0V power supply with an input port, easy to use.

Low Level Trigger

Freewheeling protection

Specification:

1. Working voltage: 5 ~ 30V, support MicroUSB 5V

Trigger Voltage : 5V (Low Level Trigger)

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. Relay: 10A / 250VAC, 10A / 30VDC load.

5. 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 modules ground and signals 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.

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

Prevent simultaneous launch multiple devices cause burning appliances or fail to start
