12V NE555 Adjustable Time Delay Relay Module
The delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.
You need to have in order to start the occasion, to prevent multiple devices
simultaneously starting current is too large burning appliances.
- Power relay delay pull. Specifically 12v power supply to the relay, the relay
- will not immediately sucked and status relay outputs are normally open
- disconnected public,normally closed and public conduction,wait until the delay
- 1-10s (adjustable),the relay suction and, this time, the relay output status is
- normally open and public conduction,normally closed and public disconnected;
- as long as uninterruptible power module, this state will remain.
- The delay time is adjustable(0 to 10 seconds)
- Increasing the potential can increase the delay time
- Increasing the capacitor C1 can increase the delay time
- With input power indicator
- With relay indicator
- Can control AC 220V / 10A about equipment. (Maximum control equipment
- With freewheeling protection relay.
- The delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf
- T = 1.1 * 100000 * 0.0001 = 11 seconds
- Size: 6.8CM *2.1CM
- The main chip: NE555
- The working voltage: 12V
- Weight: 30g
- 1 x NE555 Timer Switch Adjustable Controller Module
