2PCS DC 12V NE555 Delay Timer Relay Switch Module 0 to 10 Seconds Adjustable ...

2PCS DC 12V NE555 Delay Timer Relay Switch Module 0 to 10 Seconds Adjustable for Automotive Control System Electrical Equipment

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 can know the working status of the relay at a 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 load: 2200W Module size: 68 x 21 x 18 mm/ x x 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:
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: For example: Capacitance 100uf resistance 100K T = * 100000 * = 11 seconds
