The PCS-9710 Remote Terminal Unit (abbreviated as RTU) adapts to all kinds of substations and power plants in high, middle and low voltage levels. It supports AC & DC analog sampling, configurable binary inputs and outputs (abbreviated as IO), programmable logic, etc.
The PCS-9710 RTU is a microprocessor-controlled electronic device that interfaces objects in the physical world to one or multiple Network Control Centre (abbreviated as NCC). It adopts an object-oriented design with a unified software and hardware platforms which supports the access with nearly all kinds of intelligent device (abbreviated as IED) of NR Electric and the third party.
Flexible IO configuration
Communication with IED
Communication with dispatching center or control center
Data calculation and synthesis
Operation record and query
This device adopts a fully closed chassis with a complete panel. Completely separated spaces for electronic and electrical systems are provided.
The program is designed with anti-interference measures to enhance the device EMC.
The adoption of the new UAPC hardware platform, 16 bits parallel A/D converter, optional 320*240 graphic dot matrix LCD, and real time multi-task operating system for industrial purpose realizes a high-capacity, high-precision, fast and real time processing. With the high-precision parallel A/D converter, sampling can be conducted for all the AC signals to ensure the accuracy of analog quantity measurement.
Interlocking logic is supported in bay level. User can program interlocking logic in using the auxiliary software and download it to RTU via network.
Modularized hardware design makes this relay be easily upgraded or repaired by a qualified service person. Various function optional modules can satisfy various situations according to the different requirements of the users.
Software and hardware clock synchronization are both adopted with 1ms timing accuracy to ensure the resolution of Sequence Of Events (abbreviated as SOE).
Ethernet port and RS-232/RS-485 serial port are equiped for communication with optical fiber or twisted-pair cable.
Back plug-in module structure is adopted. Electrical and electronic circuits are strictly separated, which enhances EMC immunity performance.
Dual power supply technology based on load balance is supported.
Up to 3 extension chassis can meet enormous IO requirement.
Flexible device arrangement, including front & rear wiring, full & half-width chassis, extension HMI panel (with LED and keyboard), can satisfy different demands of cabinet installation.
