      PCS-9710 Remote Terminal Unit
    1. 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. 

    2. Functions Features
      • ?Flexible IO configuration

      • ?Communication with IED

      • ?Communication with dispatching center or control center

      • ?Data calculation and synthesis

      • ?Operation record and query

      • ?Time synchronization

      • ?Remote debugging

      • ?Auto-diagnostic

      • 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.
