Performance parameter

OneElectrical isolation

  1500Vrms isolation between input signal and power supply;

  1500Vrms isolation between input and RS485 output interface;

  1500Vrms isolation between power supply and RS485 output interface;

  110kV isolation between fiber output and input and power supply.

TwoElectromagnetic compatibility

  Digital transmission, with strong anti-interference ability.

  When the output is transmitted by optical fiber, the transmission is not affected by electromagnetic interference.

ThreeIndependence   

  Each sub station uses an independent power supply, communication system and microprocessor, each sub station has a strong independence, a sub station does not affect the normal operation of any other sub station.

  The host can display the online terminal in real time.

FourCommunication protocol  

  The AnyBus asynchronous serial communication protocol which is suitable for synchronous high speed sampling is adopted. Single channel maximum sampling frequency up to 100kHz. Even if the 100 channels synchronous sampling, sampling frequency can also reach more than 1000Hz.
