Relay Micro usb TDR timer delay relay off ne555 trigger switch 5v-30vsudah solder menggunakan awg20 kabel dengan panjang 10cmSmart Electronics 5V-30V Micro USB Power Adjustable Delay Relay Timer Control Module Trigger Delay Switch Description: 1. The time can be adjusted by potentiometers to meet the needs of most of your occasions. 2. With MicroUSB 5.0V power input it is very convenient to use.3. 5--30V ultra wide supply voltage. 4. External triggering and onboard buttons are two trigger modes. 5. With relay suction indicator. 6. The anti-interference ability is strong and the relay will not misbehave under all kinds of disturbances so it is suitable for industrial control. Feature: 1. Working voltage: there are two kinds of power supply interfaces between wide voltage 5--30V arbitrary voltage MicroUSB and welding terminal. 2. Working mode: A. After supplying power to the module the output state of the module is: normally on (NO) and the common end (COM) disconnected normally closed (NC) and the common end (COM) conduction. B. The relay sucks and operates when a low pulse signal is given to the TRIG or when the trigger button is touched and the indicator light is on. At this time the state of the output of the relay is normally on (NO) and the common terminal. C. (COM) on normally closed (NC) and the public end (COM) off after 0-24 seconds (this time can be adjusted according to your needs) after the clock relay off at this time the relay back to the state before triggering. 3. Time can be adjusted by potentiometer with a default of 0-24 seconds. If it takes longer you can replace the larger capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example capacitance 22uF resistance 1M. T=1.1*0.000022*1000000=24.2 seconds. 4. With relay suction indicator. 5. Module can be controlled: 10A 250VAC (AC) 10A 30VDC (DC) below load. 6. With Relay follow current protection.
