Sobre este producto
- Main Chip:NE555; Operating voltage: DC 12V; Can be controlled AC 250V/10A /DC 0~30V/max. 10A equipment. (Maximum control equipment 2000W).
- The delay time is adjustable (0-10 seconds), Increase the potentiometer can increase the delay time.
- NE555 delay module, 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 .
- With input power indicator, with the relay is energized light.You can know the working status of the relay at a glance.Test phenomenon: After powering on, the red power indicator light lights up. After a delay of 1-10S, the relay engages, a "click" sound is heard, and the blue relay engages the indicator light.
- Useful for applications in equipment-delay to prevent sudden high current which can burn components and devices.

Specification: Main chip: NE555 Delay modue: delay connect module Working voltage: DC 12V Adjustable delay 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: 68 x 21 x 18 mm/ 2.67 x 0.86 x 0.7 inchs Over-temperature protection: automatically shut down the output after over-temperature Applications: Vehicle equipment delays prevent car ignition and prevent sudden high currents from burning components and devices. Module performance and features: 1.Turn on the power and the relay will delayed pull-in(This module only has a delayed pull-in function and no delayed disconnect function unless the power is off): For detail: 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 Package include: 2 x NE555 Delay Timer Relay Module Switch
