product detail
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
