5V-30V Micro USB Power Delay Relay Timer Control Module Trigger Switch, 501 Original

Smart Electronics 5V-30V Micro USB Power Adjustable Delay Relay Timer Control Module Trigger Delay SwitchDescription: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.7. The module signal terminal is designed with a pull up and filter circuit, which has strong anti-interference ability and is suitable for industrial control. The relay will not malfunction whether in the electromagnetic interference environment or in the instant when the module is on or off.Application:1. Anti theft alarm delay, building sound and light control switch.2. The delayed connection of the on-board equipment prevents the electric current from burning when the car fires, and burns the vehicle equipment.3. It is necessary to have sequential startup to prevent multiple devices from starting at the same time and overburning the appliance.Specification:Size: 54*20*16mm/2.12*0.78*0.62''Note:Please allow 1-3mm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding. 1 x Relay Timer Control Module
