12V Delay-off relay module delay switch robot smart car accessories DIY essential

2013 12V Delay-off relay module; delay switch; robot; smart car accessories; DIY essential

First, the size: 6.8CM * 2.1CM

Second, the main chip: NE555

Operating voltage: 12 volts DC

IV characteristics:
1 power relay closing and opening of a fixed period of 1-10s. Specifically: 12v power supply to relay, the relay will immediately suck and state relay outputs: normally openand common pilot way, normally closed disconnect with the public; wait until the delay–10s (regulation), the relay release, this time, the state of the relay outputs: normally open disconnect with the public, normally closed and common pilot pass;, this state will remain fixed to 1-10s, as long as the module uninterruptible power cycle pull and release.
2, the delay time is adjustable (0-10 seconds)
4, increase the potentiometer can increase the delay time
5, increasing the capacitance C1 can increase the delay time
6, with input power indicator
7, with the relay is energized light

8 can be controlled AC 220V/10A equipment. (Maximum control equipment 2000W)

9, with a the relay continued flow protection.

10, the delay time formula: T = 1.1RC. For example: capacitor 100uf resistor 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
