Electronic Control System

Introduction

▪ Frame structure control cabinet,

▪ lmported electrical elements.

▪ Impored temperature control system,

▪ lmported driving system.

▪ Interiock and multi-protection

▪ Adopting imported PLC (OMRON or SlMESito achieve optimized process control.Stronger function,steady performance and much higher accuracy

▪ It can be also accomplished full-set link-lock protection, trouble safequard fault alarm cluing and so on

▪ Operation interface on touching screen is visual and marked, which is brief and easy to use

Technical Parameters

  PLC Electrical Instrumentation Control System

1. The control system uses the following brands:
