1.Summarize

1.1 The controller expansion boards is designed to improve traditional control box wiring method.
1.2 Controller expansion board wiring is more reliable, safer, more organized, more time-saving than the traditional control box wiring.
1.3 It applies to all controllers and generating set between the input and output signals, and control signals associated with the connections.

2.Characteristic

   2.1 Labor-saving, space saving.Maximize savings  the cost of labor.
   2.2 More reliably than the traditional way of wiring running, safer. Maximize enhancement of the assembly product quality;        
   2.3 to achieve nice appearance after assembly   
   2.4 The controller expansion boards module uses the insulating resin encapsulation.
         Have the features of corrosion resistance, high insulation, high pressure resistance
         and anti-vibration. it can be work applied to all kinds of bad environment..
              
3.Basic functions   
                           
3.1 Startup , fuel ,parking relay. Put the power of the controller starts and the fuel relay to expand to 30A.Parking or preheat relay power extended to the normally open 20A;normally closed 10A.
ATS mains and power conversion control with the controller.                    
3.2 Mains automatically start.
