VKLSVAN 3 PCS NE555 DC 12V 0-10 Seconds Adjustable Features
-
High Power High Efficiency: 12V module. The output can be connected to AC 250V 10A and DC 0-30V/max.10A equipment, and the max control equipment is up to 2200W.
-
The timer switch relay module can be adjustable timer delay(default setting:0-10s) and counter clockwise adjustment of potentiometer to increase delay time. High reliability, strong vibration resistance, good electromechanical performance.
-
Which consist of high-precision potentiometer ( adjust the output frequency), high frequency filter capacitor and with input power indicator, with the relay is energized light .
-
NE555 chip features: Timing from microseconds to long hours, simple circuit design, high pulse generation / timing accuracy, adjustable duty cycle, wide application range, large amount of information.
-
A wide range of applications: The adjustable timer switch relay module is designed with relay module continuous current flow protection. This module is perfect for SCM learning, electronic competition, product development, graduation design and so on.
About VKLSVAN 3 PCS NE555 DC 12V 0-10 Seconds Adjustable
Product specification: Main chip: NE555 Delay modue: delay connect module Working voltage: DC 12V Adjustable time : 0-10 seconds(counter clockwise adjustment of potentiometer to increase delay time.) Control voltage: AC 0~250V/max. 10A, DC 0~30V/max.10A Max load: 2200W Module size: approx 68mm x 21mm x 18mm/2.67 x 0.86 x 0.7 inchs Over temperature protection: Automatically turn off the output after over temperature Weight: 16g/pcs Module performance and features: 1.Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power , the relay will immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction; wait until the delay is 1-10s (can be adjusted), the release of the relay and at this time, the state of the relay output is:Normally open and public conduction, normally closed and public disconnect; this state will be maintained as long as the module is continuously powered. 2. The delay time is adjustable, (0 ~ 10 seconds) 3. Increase the potentiometer can increase the delay time 4. Increase the capacitance C1 can increase the delay time 5. Possess of input power indicator 6. Possess of relay pull-in indicator 7. can control the AC 220V/10A equipment. (Maximum control device 2000W) 8. Possess of relay freewheeling protection 9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds Applications: Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices. Package include: 3 x NE555 Delay Timer Relay Switch Module 0-10 Seconds
