Product Description

  phoforelay control module  

 lcrm*1 type 1 relay module , adopt high quality industrial grade componenis , military rank double faced pcb plate , with red and blue led signal indicator . cloth plate consider comprehensive , module stable performance , can be widely used in all kinds of intensity measurement control occasion .

  a function characteristics 

1, use photosensitive resistor light induction 's strength , syncronisation high quality relay direct control ac or dc load ,normally open interface the maximum load capacity : ac 0v****0v / *0a dc 0v***0v / *0a .
2 , can potentiometer adjust sensitivity , through adjust potentiometer , set starter relay valve value , hereat when the dark valve value when , module relay pickup , hereat bright valve value when , relay release .  

 3smart design adjust , when relay after , auto tuning action valve value , solve the critical value of the action problem repeatedly . 

4 , module proof reversal function , plug power supply not damage module . 

5 , equipped with power indicator red ( ) , *-channel relay status indicator blue ( )
6 , module work voltage have 5v , *2v preparability , expecially userdata indicate the . 

 7 , with 4 a fitted bolt hole , convenient installation
8 , module measurement :5.0cm*3.0cm* 1.8cm .

 9 , module free*0cm phtoresistor long pie-tail detection .

 how to use 

1 , photosensitive resistor module for the light sensitive , generally used to test the ambient light brightness change

 2 , module light in environment dark at threshold , relay pickup , common and switching-in germinant often ( and normally closed end ) , when the outside light bright at threshold , relay Break , common and often the beginning disconnect ( and normally closed end switching-in ) .

3 , common , normally open and normally closed three ports equivalent to a double control switch , relay coil electrical when , common and breakover germinant of euchromatin , none power , common and normally closed end breakover .

 electrical parameter

work voltage : dc 5v , *2v two kinds of optional ( should not exceed voltage 's nominal + / - *0% ) 

 current : 5v less than when *0ma ( relay not less than 's movements 5ma ) 

   *2v less than when *0ma ( relay not less than 's movements 5ma ) 

 working temperature : recommended - *0 mdash . *0 ( limit temperature range - *0 mdash . *0 ) 

load capacity : relay normally open port maximum load ability : dc ***0v / *0a ac ****0v / *0a 

          relay normally closed port maximum load ability : dc ***8v /*0a ac ****5v /*0a
