MR-502 controller application mode
In the MR-502 controller applications,applications can be divided into sync cable and 
AC power frequency synchronization and other various application mode.

I. Sync cable Application
 In the MR-502 controller sync cable applications,by using the synchronous line in the 
MR-502 controller to realize synchronization between the controllers。In this application 
mode,By setting the 1st controller to achieve a unified control of the subsequent 
controller,for example:Segment selection、Speed adjustment settings.
MR-502 controller Applications

  1. DC power supply range:DC 7V-24V;

  2. Sync cable using shielded twisted pair or five twisted pair,Wire cross-sectional area 
    of not less than 0.5 mm,The length of not more than 150 meters.

II. Application of AC frequency synchronization
    In the AC power frequency synchronization application,controller adopt AC power 
    supply(AC 12V),MR-502 controller support AC synchronous,The project uses a switch
    all controllers to control the power,By electrically controlled simultaneously to achieve 
MR-502 controller Applications

  As shown above,MR-502 controller uses low-voltage AC(AC9V) power supply,By the 
transformer power supply,Through a switch to control the fire wire AC220 AC,to achieve 
all the controller on power at the same time.
