ABB VA-3180-10 is a high-performance programmable logic controller(PLC)designed for industrial automation systems.It has a modular architecture,high reliability and wide applicability.The following is a comprehensive overview of its core functions and technical features:
I.Core functions
Motor protection and control
-Light load/no-load protection:The protection action is judged by the ratio of line current to rated current,and alarm or delayed tripping is supported.
-Ground fault(leakage)protection:An external zero-sequence current transformer is connected to achieve instantaneous or delayed tripping when the leakage current exceeds the limit.
-Motor thermal protection:The motor winding temperature is detected based on the resistance value of the PTC thermistor to trigger the over-limit protection.
-Start number limit:The number of allowed starts within the set time interval is prevented from damaging the motor due to frequent starts.
Motor control method
-Programmed control:Supports multiple starting modes(such as star-delta,auto-coupling step-down,etc.),and monitors the contactor status through auxiliary contact feedback.
-Authority management:Distinguish the priority of on-site(local)and remote control to ensure operational safety.
2.Technical Features
Modularity and Scalability
-Supports flexible expansion of input/output modules to meet the needs of systems of different scales.
-Adopts standardized interface design and is compatible with industrial communication protocols(such as Modbus,Profibus).
Programming and Maintenance
