Power relay closing and opening of a fixed period of 1-10s. Specifically: 12v power supply to relay, the relay will immediately suck and staterelay outputs: normally open and common pilot way, normally closed disconnect with the public; wait until the delay-10s (regulation), the relayrelease, this time, the state of the relay outputs: normally open disconnect with the public, normally closed and common pilot pass;, this statewill remain fixed to 1-10s, as long as the module uninterruptible power cycle pull and release.
The delay time is adjustable (0-10 seconds)
Increase the potentiometer can increase the delay time
Increasing the capacitance C1 can increase the delay time
With input power indicator
With the relay is energized light
Can be controlled AC 220V/10A equipment. (Maximum control equipment 2000W)
With a the relay continued flow protection.
The delay time formula: T = 1.1RC. For example: capacitor 100uf resistor 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
