Modular remote terminal unit PCS-9710

RS-485RS-232Ethernet

Product Overview
The PCS-9710 Remote Terminal Unit (RTU) is designed for substations and power plants across high, medium and low voltage levels. It provides AC and DC analog sampling, configurable binary inputs/outputs, user-programmable logic and standard RTU services for interfacing local equipment with one or multiple Network Control Centres (NCC). The unit uses an object-oriented software/hardware platform and supports NR Electric IEDs and compatible third-party devices.

Functions

• Flexible configuration of digital and analog IO
• Communication with IEDs and protection devices
• Supervision and telemetry to dispatch or control centres
• Data calculation, aggregation and archiving
• Operation logging and query
• High-precision time synchronization (SOE)
• Remote debugging and maintenance
• Automatic self-diagnostics

Features

• Fully enclosed chassis with separate compartments for electronic and power circuits
• EMC-enhanced program design and physical separation to reduce interference
• UAPC hardware platform with 16-bit parallel A/D converter for precise sampling
• Optional 320 × 240 graphic dot-matrix LCD
• Real-time multitasking industrial OS for high-capacity, low-latency processing
• Parallel A/D sampling of AC signals for accurate analog measurement
• User-programmable bay-level interlocking logic downloadable via network
• Modular hardware design and back plug-in modules for easy upgrades and repairs
• Software and hardware clock synchronization with 1 ms accuracy for Sequence Of Events (SOE)
• Ethernet and RS-232/RS-485 interfaces for fibre or twisted-pair communication
• Dual power-supply with load-balance technology
• Support for up to 3 extension chassis to expand IO capacity
• Flexible installation: front/rear wiring, full/half-width chassis, optional HMI extension panel (LED and keyboard)
