Main Features

1) The hardware structure is modularized, fully sealed, with metal chambers for each module within the unit, complete self checking and redundancy measures, and good anti-interference performance;

2) The software is designed to be open to control objects, achieving modularity, and can query CPU status and protect intermediate processes;

3) The human-machine interface consists of a wide temperature large screen LCD display and thin film buttons, with information displayed in Chinese;

4) Detailed and high-capacity event recording function, convenient for analyzing accidents and observing operating conditions;

5) The protection action information and warning information can be converted from units into remote signaling for transmission, improving the real-time performance of action and return information;

6) The protection trip logic outlet can be flexibly configured for on-site debugging;

7) The hard control pressure plate for protection input can be flexibly configured and converted into remote signaling transmission.

8) Combining the function of AC switch waveform recording, on-site display of waveform recording, and backend software analysis;

9) Communication can use CAN network, 485, fiber optic, Ethernet and other media to communicate with the monitoring system in single network, dual network, or triple network modes. The communication speed is fast, the reliability is high, and it supports the IEC60870-5-103 standard;

10) 32-bit DSP and 16 bit AD wide analog-to-digital conversion, 24 point/cycle sampling, fast computation speed, high sampling accuracy;

11) The measurement accuracy coefficient sheet is stored in the E2 PROM of the AC sampling module, which has good stability and is easy to maintain;

12) Protect the storage of E2 PROM/DSRAM with multiple opposing fixed values, automatically verify each other, and self repair to avoid missing or lost fixed values during operation;

13) The unit comes with a built-in buzzer device and a fault alarm;

14) The operation of circuit breakers and non electric circuits meet the requirements of countermeasures;

15) The device can be connected to a printer for local Chinese character printing events, waveforms, and settings;

16) Using a hardware real-time clock that continues to time even after power failure, GPS differential, node, and communication timing can be used;

17) Equipped with output and signal testing functions, convenient for on-site debugging;

18) It can be set locally or remotely, with a storage capacity of 15 sets of fixed values. The standard program for the generator series only sets one set of fixed values;
