5V-30V Delay Relay Timer Module Trigger Delay Switch Micro USB Power Adjustable Relay Module

This module designed as  5V-30V Delay Relay Timer Module Trigger Delay Switch Micro USB Power Adjustable Relay Module. In this relay module, operates with two kinds of power supply interfaces between wide voltage range of  5–30V, arbitrary voltage, also  MicroUSB and welding terminal. Thus makes it very convenient to use. Here the time can be adjusted via a potentiometer, meeting almost all requirements of the user.

This module is a Delay Relay Timer Module with a 5V-30V voltage range. Micro USB Power Adjustable Relay Module Trigger Delay Switch This relay module has two power supply interfaces: a wide voltage range of 5–30V, arbitrary voltage, as well as MicroUSB and welding terminal. As a result, it’s quite easy to use. A potentiometer may be used to change the time, which meets practically all of the user’s needs.

This C. (COM) is turned on, typically closed (NC), and the public end (COM) is turned off after 0-24 seconds (this duration may be changed according to user requirements) after the clock relay is turned off. At this point, the relay returns to its pre-trigger condition. It’s also excellent for a broad range of applications thanks to the relay suction indication feature. Here, a potentiometer controls the time, which is set at 0-24 seconds by default. Replace the bigger capacitor (C2) or the potentiometer if it takes longer.

Delay time formula: T = 1.1RC.

For capacitance =22uF resistance 1M.:  T=1.1*0.000022*1000000=24.2 seconds.

With Relay follow current protection, this module signal terminal designed with a pull up and filter circuit. It offers strong anti-interference ability and is perfect for industrial control. In certain cases, when the module is in an electromagnetic interference environment or in the instant when the module is on or off, the relay will not malfunction.
