Technical Features (4) All Boards can be plugged in or out with system power on In the cabinet of DF 1331, it is electrically isolated among all the boards and also between the boards and the site connections. There are no direct electrical connection among them. The electrical-magnetic isolation, electrical-optical isolation, and so on have been considered thoroughly in the design. Each board can be plugged in or out when the system in running without damage to anything. This design increases the stability of the whole system and makes it convenient for the site debug and maintenance.

Technical Features (5) Convenient for Connection with all kinds of Systems v A 1331 MCP has 10 serial ports and also Ethernet ports, and all of them can be expanded for more. Each communication port can be set in different protocols for connection with all kinds of intelligent systems such as dispatch center, or protection relays, meters or GPS etc in substation to form the Substation Automation System. v Abundant protocols library available in DF 1331 system, such as IEC 60870 -5 -101, IEC 60870 -5 -102, IEC 60870 -5 -103, IEC 60870 -5 -104, DNP, CDT 92, CDT 85, RP 570, RP 571, 8890, U 4 F, MB 88, MODBUS, SCI 1801 V 6, ISA, LFP, XT 9702 etc.

Technical Features (6) Convenient Local and Remote Maintenance Functions You can program the RTU with the provided maintenance software in a portable computer on site or even a thousand miles away through the public telephone net or Internet. You can do all the things remotely as you can in the substation. Many things can be solved in your office. No erase or write to the EPROM is needed. With the remote maintenance function, our support technician can also help you to keep the DF 1331 running in the correct mode.

Technical Features (7) Support Mixed Modes of Analog Signal Sampling The 1331 AI board is designed for the DC analog sampling with a very high accuracy. 1331 ACAI AC analog input boards designed for flexible sampling of the AC signal without transducers with very high accuracy and stability. All the current inputs can be set flexibly with different voltage inputs for the calculation of power. It can be set to start high speed sampling for each channel at a rate of 64 to 128 points per cycle for the display and analysis of the waveforms and calculation to the 31 st harmonic.

Technical Features (8) Dual MCP Hot-backup mode improves the reliability v In some special requested applications , such as in some ultra-high voltage substations or plants, dual 1331 MCP can be configured as the dual main communication processors of the system. These two MCP units work in the hot backup mode for each other. One is the main processor, the other works in hot backup mode, that is, they have the same configuration parameters and same application software and data base are synchronized with the main one. As there are some faults occurs in the main one, the backup one will be take placed as the main processor. v Dual MCPs backup, dual serial ports backup , dual Ethernets backup.

Technical Features (9) PSOS--Embedded Real Time Operation System Optional v 1331 MCP-1 units and the IEDs have the PSOS embedded real time operation system. PSOS system is specially designed for ultra-high reliability and real time quality industrial control system, its cores had been certificated by FAA and FDA, and which had been used in Boeing airplanes. v PSOS system provides many kinds of standard protocol packages, such as TCP/IP, PPP, X 25 etc, and that make it easy for DF 1331 system to connect with many kinds of LAN (local area net) or WAN.

Technical Features (10) High level EMC Capacity v Many new technologies on the Electro Magnetic Compatibility are adopted in the DF 1331 system, and it passed most of the IEC 61000 -4 IV class test standards set. v DF 1331 has good shielding and grounding structure, and at the same time, it has thorough consideration for ventilation and heat loss and anti tropical climate to ensure the long term stability working.

Technical Features (11) Some other Designs for High Reliability v DF 1331 adopts unique ‘long password lock’ technique and current-limitation technique and some other techniques which assure that even in the worst situation, no wrong control output will occur. v Anti chattering design is adopted in the digital input sampling software and anti interference design is adopted in DI hardware. v Thorough self test functions are available. v Dual power supply automatic switch design in the power supply unit, AC or DC power supply are all permitted.
