NE555 delay monostable switch module Delay switch (12v) vehicle electrical delay

Description:

• Chip: NE555
• Dimension: 68mmX21mm
• Working Voltage: DC 12V

Feature:

• Switch on the power relay with 1-10S fixed period suction close and disconnect. Specific for: to relay for 12V power supply, relay will soon suction and relay output of the state for: normally open and public conduction, normally closed and public off; Until the time delay 1-10S (regulation), relay release, at this point, the relay output of the state for: normally open and public disconnect, normally closed and public conduction; As long as the module uninterruptable power, the state will always keep to 1-10S fixed period suction together and release.
• delay time is adjustable, (0 ~ 10 seconds)
• add potentiometer can increase delay time
• add capacitor C1 can increase latency time
• with input power light
• with relay and indicator lamp
• can control device with AC 220 v / 10 or below. (maximum control equipment 2000 w)
• stream with relay protection.
• the delay time formula: T = 1.1 RC. For example: 100 uf capacitance resistance 100 k T = 1.1 * 100000 * 0.0001 = 11 second

•  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.
