2 uses the perfect smart delay chip , using voltage range , output delay characteristics of stability ;
3 power supply has increased electrolytic capacitor filter , and noise suppression capacitor , to prevent unstable power supply module for delay effects ;
4 power supply output with anti- reverse diode , the effective protection module ;
5 trigger side with optocoupler isolation , the trigger reliable performance and stability , to prevent the occurrence of false triggering ;
6 with support for high level trigger , low trigger , normally open ( switch on ) trigger , normally closed ( switch off ) trigger pulse trigger edge is also supported , supports a variety of vibration sensors, reed sensors, tilt angle sensor , triggering a variety of sensor module , microcontroller triggers , etc. ;
7 high-low latency output can choose ;
8 with 8 time ranges selected shortest 0.1 second up to 1 hour to satisfy most requirements of people at different times ;
9 module with low power consumption.
Performance indicators:
Power requirement :4-12VDC power :4-12mA ( the size and power )
Drive Capability :> 15mA Ambient temperature: < 80 degrees
Delay Stability: set a good time , every time delay error is less than 1%
Module size : 32 X 30 X 12mm
Module wiring :
VCC: positive power supply
GND: tied to power supply
OUT: delayed output ( switching signal output , close to the power )
Signal triggers the end of the module described ( see below illustrates how jumpers trigger ) :
1. high level trigger ( pulse rising ) : trigger level is greater than 4V, less than 12V can be accessed by all can trigger a variety of microcontroller I / O ports , sensors, modules, etc. ;
2. low level trigger : trigger level to trigger less than 1V , microcontroller used trigger mode ;
3 normally open ( switch on ) trigger : this trigger are widely used, then the shock sensor alarm trigger delay can be done , then do tamper switch alarm delay gate , then tilt switch tilt alarm delay can be done ;
4 normally closed ( switch open , the line is disconnected ) Trigger: commonly used in the detection of the line , the original line is turned off , it will trigger delay .
Delay range of options :
This module has eight selectable time ranges for different time requirements, select the appropriate time range can be accurately achieved , refer to the following figure how to select the time range.
High and low output module delay selection
When S3 is set to 1 , OUT output on the delay , when S3 is set to 0 , OUT output low when the delay .
