555 Delay Switch Module for Controlling Power Delaying
Features:
- on power or an external key switch is triggered, the relay delay is adjustable from 1 second to 10 minutes, turn on or off the relay contacts.
- open relays and off lights.
- the time the action is less than about 0.5 seconds, closing relays, protection delay driver IC.
- oval design with mounting holes, even if you missed the point of the positioning hole, does not prevent the installation.
- PCB board size: Length: 55mm / Width: 25mm / height: 2.7mm / (height means that contain the highest capacitance)
- 12 V 12VDC power supply is connected to the positive
- GND 12VDC power supply is connected to the negative
- the trigger switch is connected to the trigger signal
- normally open or normally closed port and the common point of any controlled electrical relay port access
Scope:
- can delay the high-pressure tube amplifier power panel for controlling the opening.
- one-shot mode. Add a normally open button. One-shot routine can control.
- for other occasions delay control.
- a plurality of circuit modules together, you can achieve linkage delay control. Intelligent control. You can do simple like PLC control.
Parameters:
- input voltage: 12V
- the input current: greater than or equal to 50MA.
- the switch control parameters: voltage 0-240V, AC / DC, current 0-10A.
Instructions:
- A blue potentiometer clockwise to shorten the delay time is adjusted counterclockwise tune is to extend the delay time, the board shall be 1 second delay delay or 1 second to 3 minutes to 10 minutes delay
- after the board shall set the delay time delay, a power (lights) on conducting trigger delay, the delay time is up, lights off. Then again, the trigger will again delay it.
- immediately after a trigger (for a short time) to hear the "da" sound, continuous continuous trigger the "da" sound, which means that the shortest delay has to be 0 seconds, then may adjust the potentiometer counterclockwise, then trigger the desired delay time slowly adjusted.
- remember: power is not greater than 12V, and the power of positive and negative can not be reversed.
