1.2 Main

features

◆

Reinforced  unit  chassis  is  designed  to  resist  strong  vibration  and  interference,  especially

suits for harsh environments. It can be decentralized mounted in the switch cabinet for running.

◆

All integrated circuits use military-grade standards to ensure higher stability and reliability.

◆

Using 32-bit MCU as CPU, configures large-capacity RAM and Flash Memory, with strong

ability  of  data  processing,  logic  operation  and  information  storage,  fast  running  speed  and

high reliability.

◆

16-bit  A/D  is  used  for  data  acquisition,  data  acquisition  is  24  points  per  week,  and  the

protection measurement accuracy is high.

◆

The  graphic  LCD  screen  can  display  various  operating  states  and  data  in  real  time,  the

information  is  detailed  and  intuitive,  and  the  operation  and  debugging  are  convenient.

◆

Large  capacity  information  record:  It  can  save  no  less  than  32  recent  events  historical

reports,  with  action  parameters,  power-down  retention,  easy  for  accident  analysis.

◆

Adopts  MODBUS-RTU  protocol  with  RS-485  communication  interface.  The  networking  is

economical and convenient, and can directly communicate with the computer monitoring and

gateway.
