ABB REF543KB127AAAA communication and measurement module is a powerful device, mainly used to realize the communication and measurement of various data in the power system. The following is a detailed introduction to the module:
Main functions:
Communication and measurement: The REF543KB127AAAA module can be used in combination with various switchgears (such as single bus, double bus and dual machine systems) to meet the needs of different systems.
Protection function: Supports multiple types of networks, including neutral point ungrounded networks, arc suppression coil grounded networks and partially grounded networks, ensuring stable and reliable protection in various network environments.
PLC function: In addition to basic protection, measurement, control and status monitoring functions, the REF543KB127AAAA module also provides rich PLC functions, enabling it to play a greater role in substation automation systems.
Application areas:
The REF543KB127AAAA module can be applied to the protection and control of medium-sized three-phase asynchronous motors and reactive power compensation shunt capacitor banks, showing its diverse application characteristics.
In terms of power system monitoring and control, it can be connected to devices such as current and voltage sensors to monitor various parameters in the power system, such as current, voltage, power factor, etc., and perform control operations when necessary to ensure the stable operation of the power system.
Data communication:
The REF543KB127AAAA module supports multiple communication standards, such as SPA bus protocol, LON bus protocol, IEC 60870-5-103 protocol, etc., enabling it to seamlessly connect with various upper-layer devices to achieve real-time data transmission and sharing.
With the support of SPA-ZC 400 and SPA-ZC 302, the module is also compatible with IEC 61850 and Profitbus DPV1 protocols, further expanding its communication capabilities.
Technical features:
Voltage and current measurements are performed through traditional measuring transformers or current and voltage sensors.
Fixed human-machine interface, including large graphic display, or external display module for flexible switch cabinet installation.
It provides protection functions such as non-directional and directional overcurrent and ground fault protection, residual voltage, overvoltage and undervoltage protection, thermal overload protection, CBFP and automatic reclosing.
