] uses high performance arm Cortex-M3 32-bit RISC core. The three signals acquisition, recording, display and a road traffic transmission output (transmission output need to customize the user) are realized at the same time.
We use the historical data of the FLASH flash memory chip 256M storage capacity, it never lost data;
The application of the advanced CAN bus function, can be set up to facilitate the field instrumentation system
The flow, temperature compensation and pressure compensation input, and input a variety of signal, no need to replace the module, through the configuration software can be.
The numerical range of engineering quantity data show wider, can display 4 digit value: -999~9999;
] in addition to standard serial communication interface support: RS232C, RS485, can field bus; support Modbus RTU protocol. Note: the opening of communications can be customized
The parameter setting of the clipboard to copy and paste functions convenient for users;
Support external Mini printers, manual print data, curve, to meet user needs to print the scene;
The 2 way relay alarm output, while indicating various alarm limit, lower limit, upper limit, lower limit alarm;
We use the historical data of the FLASH flash memory chip 256M storage capacity, it never lost data; for flow totalizer escort
It is equipped with a standard USB interface, can timely and accurately all traffic data stored locally, more convenient measurement of energy enterprises
Real time clock - meter integrated hardware, power down clock can be more convenient operation, enterprise management;
] use, green switch power supply, DC dual-purpose, 85 ~ 264Vac or 120 ~ 370VDC input voltage, input frequency range 47 ~ 63Hz;
] a variety of additional features optional: historical curve, variable transmission output, printing, 24VDC distribution. Note: the opening of additional features to be customized.
The fully customized concept, make use of flow totalizer is more convenient, more complete products make more reasonable
