12V NE555 Adjustable Time Delay Relay Module

The delay module is turned on, to prevent excessive current.

Features

• Power relay delay pull. Specifically 12v power supply to the relay, the relay will not immediately be drained and status relay outputs are normally open disconnected public, normally closed and public conduction, wait until the delay 1-10s (adjustable), the relay suction and, this time, the relay output status is normally open and public conduction, normally closed and public disconnected; as long as an uninterruptible power module, this state will remain.
• The delay time is adjustable (0 to 10 seconds)
• Increasing the potential can increase the delay time
• Increasing the capacitor C1 can increase the delay time
• With input power indicator
• With relay indicator
• Can control AC 220V / 10A about equipment. (Maximum control equipment 2000W)
• With freewheeling protection relay.
• The delay time formula: T = 1.1RC. For example: a resistor-capacitor 100uf 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
