RW1725IED RTU Gateway

Detailed description

  • Description
  • Technical Features

RW1725IED is an automation system used to communicate from different equipment to master control center. It is a micro processor based device. Unified design is intended to reduce the wiring and maintenance costs. The RW1725IED retrieves data from legacy and third party devices such as relays, transfers it to a host or enterprise system, monitors and expands to meet future physical and functional station requirements.

RW1725IED follows the IEC international standard, adopting advanced power monitoring technology. The system has good real-time performance, reliability, interoperability and openness, suitable for the comprehesive and real-time monitoring and control for the company which works on the primary and secondary equipment electrical installation regarding to the power plants, substations, and distribution networks.

RW1725IED module has a variety of functional plug-ins, adaptation to a variety of AC and DC power supply, and can achieve the acquisition of a variety of signals. In addition to the four-remote function with telemetry, digital input, digital output, and remote adjustment, the module also has circuit breaker synchronization check, deadline check, remote control block, and Ethernet communication function. It supports the programmable logic control (PLC) function, and can realize the operation latch of a single electrical unit and the operation interlock scheme between different electrical units.

The module has the advanced distribution automation processing function, and can cover the feeder, the switch station, the open and close device, the cable dividing room and the distribution room, the low voltage substation and other distribution automation domain, realizing the distribution automation monitoring, automatic fault identification and processing (DA).

RW1725IED uses high-performance embedded 32-bit processor, CPLD and real-time multitasking operating system with flexible configuration. It has rich communication library, supporting many international standard protocols, including 101/104/103/DNP3.0/Modbus/IEC61850, and can connect and communicate with various intelligent devices. All communication interfaces conform to IEEE and IEC standards.
