Main Features and Functions

l  Product Universalization: The protection function can be freely configured according to the actual requirements with optional operation mode.

l  Programmable Logic Function: Protection functions, output relays and digital inputs have logic configuration function. Protection interlock, user-defined protection and relay outputs can be adjusted freely and achieved easily by non-electric protection function and blocking protection function.

l  Highly Integration: Integrate the functions of protection, measurement, control, monitoring, communication, fault recording and event recording into one device.

l  Friendly HMI: Dynamic displays single line diagram, real-time waveform, fault recording diagram, start-up waveform, etc. on the large LCD.

l  Multiple Communication Functions: Provide Ethernet communication interface (optical port and electric port), RS485 and RS422 serial interface with communication baud rate up to 19200bps; Support Modbus RTU and Modbus TCP communication protocols; It can realize the transmission functions of remote measuring, remote signalling, remote control, protection setting value settings and enquiries, device working status, SOE, fault recording data, etc.

l  Supporting PA Config Configuration Software: it is more convenient to read, download and modify the parameters and setting values of the protection relay.
