Features
l On the premise of 24 samples per cycle, all data measurement, calculation and logic discrimination could be done within one sampling period. The event recording and protection logic calculation are completed simultaneously.
l Definite time and inverse time characteristics of overcurrent protection are both provided.
l The wide range of adaptive power supply is 88 – 264 VDC and 95 – 240 VAC. The power can be supplied from the distribution system.
l The relay provides remote clock synchronization via RS-232 communication port.
l The device provides human-machine interface and associated communication port which give access to change setting value and read fault record data, etc.
l The format of event report is compatible with international COMTRADE file.
Key Benefits
l More Reliable
Based on the fully numerical platform, NR developed the optimized solutions for distribution system with advanced hardware and innovative technology to enhance the safety and reliability.
l More flexible
Many optional functions and programmable logics are provided to customize the device for your particular applications. The user can select the optional AC inputs, analog outputs, binary inputs, binary outputs, LCD, etc.
l Easy to maintenance
The user can set all configurable logics and programmable I/O, read/write data, troubleshoot and test via RCS-PC assistant software.
l Save your cost
The PCS-9690 integrates protection, control, metering and monitoring functions in one package. And the communication port with automation system reduces the maintenance cost.
