Advantages of Photo-coupler Terminal Blocks

1, a signal consumption is small, the switching frequency is high;
    
2, without mechanical movement, no contact bounce, grinding newspaper to switch long life, high voltage insulation;
    
3, are not afraid of vibration;
    
4, the volume from the location restriction, convenient wiring.

Photo-coupler Terminal Blocks purposes:

   
AC voltage, current loop for power system protection, requirements the points against measures "to strengthen the anti-interference capacitor place.
 
Photo-coupler Terminal Blocks function:

Energy state to protect the AC input circuit via the terminal "noise" can be filtered interference, the interference of "noise" can be filtered through this terminal.
 

Photo-coupler Terminal Blocks Features:
 
   
Directly through the terminal wiring to achieve the anti-interference function, eliminating the need for anti-jamming box, box, broaden the protective screen position;
   

2, the terminal between the ground (and capacitor) can withstand DC2500V, lasted 1min withstand test.

Optocoupler can also be applied to the high-pressure control, replace the transformer, instead of the contact relay for the A / D circuit, such as a variety of occasions.
