♫♥♫Wide voltage 5V-30V trigger delay relay module, timer module, time delay switch

 Welcome to ★SmartHome★ Store. Our concept is"Customer First.Service Attentively" !   Module highlights: Time can be adjusted by potentiometer to suit your most occasions. Have Micro-USB 5.0VPower input is very convenient to use. 5--30VUltra wide supply voltage. Two trigger modes: external trigger and on-board button. Material: Metal color:blue Strong anti-interference ability, under various interference, the relay will not malfunction, suitable for industrial control. Operating voltage:Wide voltage 5--30V Arbitrary voltage between,Micro-USBandWelding terminalTwo power interface Working model:After powering the module, the output status of the module is normally open (NO), disconnected from the common terminal (COM), and normally closed (NC) with the common terminal (COM). In the external contact (TRIG) to start a low pulse signal, or touch the trigger button instantly, the relay and the indicator light, the relay output state is normally open (NO) and the common end (COM) conduction, normally closed (NC) and the common end (COM) fault open, after 0-24 seconds (this time can be adjusted according to your needs) minutes after the relay is switched off, the relay back to the state before the trigger. Time can be adjusted by potentiometer, defaults to 0-24 seconds. If it takes longer, replace the larger capacitor (C2) or potentiometer by itself. Delay time formula: T = 1.1RC. For example, the capacitor 22uF resistor 1M is T=1.1*0.000022*1000000=24.2 seconds. With relay suction indicator light. The module can control: 10A, 250VAC (AC), 10A, 30VDC (DC) following load. Relay relay protection. Module signal end design has pull and filter circuit, anti-interference ability is strong, suitable for industrial control. Package Contents: 1x timer module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
