Package weight: 0.02 kg Descriptions: Power supply is anti-reverse, protect the chip to burn when it is reverse Power using integral filter circuit, super anti-interference Size: 6.6*1.6*1.9cm The main chip: NE555 Working voltage: DC12V
Features: 1. The relay time delay turn on when power supply is connected. Specific as follows: feed 12 v power supply to the relay, relay not immediately turn on, relay output status is normally open and public disconnect, normally closed and public connected; Wait for delay 0-25 s (adjustable), relay turn on, at this point, the relay outputs status is normally open and public connected, normally closed and public disconnected; As long as the module power continuously, this state will remain. 2. The delay time is adjustable, (0 - 25 seconds) 3. Increasing the potentiometer can increase the delay time 4. Increasing the capacitor C1 can increase delay time 5. Can control DC30V/10A or AC220V / 10A device 6. Have relay continuous current protection 7. The delay time formula: T = 1.1 RC. For example: capacitance 47uf, resistance 500 k, T = 1.1 * 500000 * 0.000047 = 25.85 seconds
Package included: 1 x NE555 DC 12V Delay Relay Delay Turn On Adjustable Switch Module 0-25S
