NE555 Time Relay Shield Timing Relay Timer Control Switch Car Relays, 5V, 12V – Durable Build, Easy to Use

NE555 Time Relay Shield Timing Relay Timer Control Switch Car Relays, 5V, 12V – Durable Build, Easy to Use.

Key Features:

• Size: 6.8CM x 2.1CM
• Main chip: NE555
• Working voltage: DC 12V/5V
• Features:
• The relay time delay and power supply is connected.Specific as follows: for 12V/5V power supply to the relay, relay not immediately and absorption, relay...
• The delay time is adjustable, (0-10 seconds)
• Increase the potentiometer to increase the delay time
• Increasing the capacitor C1 can increase the delay time
• With input power indicator light
• With relay pull-in indicator light
• It can control AC 220V/10A equipment. (Large control equipment 2000W)
• With relay freewheeling protection.
• Delay time formula: T=1.1RC. For example: capacitor 100uf resistor 100K T=1.1 x 100000 x 0.0001=11 seconds
• Applications
• The on-board equipment on the time delay, prevent excessive current when the car lighter burned on-board equipment.
• Need to have order to start the occasion, to prevent multiple devices at the same time starting current is too large burning appliances.
