1. Size: 6.8CM*2.1CM
Second, the main chip: NE555
Third, working voltage: DC 12 volts
4. Features:
1.
Power on, relay delay pull (This module only has delay pull and function, no delay disconnect function, unless power off). Specifically: after power-on, the relay will not immediately draw and, at this time, the state of the relay output is: normally open and public disconnect, normally closed and public conduction; Wait until the delay is 1-10s (adjustable delay), the relay draws and, at this time, the state of the relay output is: normally open and public conduction, normally closed and public disconnected; This state (relay suction and state) is maintained as long as the module is powered on. Test phenomenon: After power-on, the red power indicator lights up, and after a delay of 1-10S, the relay draws and will hear a "click" sound, and the blue relay draws and indicates the light.
2, adjustable delay time, (0 ~ 10 seconds)
4, increase the potentiometer can increase the delay time
5, increase the capacitor C1 can increase the delay time
6, with input power indicator
7, with relay pull indicator light
8, can control AC 220V/10A equipment. (Control equipment 2000W)
9, with relay continuous current protection.
10, delay time formula: T = 1.1RC. For example: Capacitance 100uf resistance 100K T=1.1*100000*0.0001=11 seconds
