◆ Summary
     Pors-GPV series isolators receive voltage signal from field instruments, after isolating and transmission, export standard process current or voltage to control room, PLC, DCS or field indicator.

◆ Features
     With power and over range alarm; 
    DIN rail mounting, plugable terminal;
     Power-input-output, and each channel all are isolated;
     Intelligent, digital, programmable, multiple parameters input and output;

◆ Technical index
     Accuracy: ≤0.1%
     Temperature coefficient: 50ppm/K of measuring value/100Ω load
     Operating temperature: -10~+70℃
     Insulation resistance: ≧100MΩ /500VDC (between power, input, output, channel, communication)
     EMC: compliance to GB/T18268, IEC61326-1
     Power supply: DC24V±10%
     Power consumption: < 1W (1 in 1 out)
     Outline size: 22.5*99*114.5mm 

◆ Indicator
     PWR: power indicator (green)
     ALM: input alarm indicator (red)
               not light when normal working    
               Flash when input is open-circuit, short, inverse connecting, and over range;

◆ Output status
     Without special ordering, in full span, the output varies following up the input signal whether any fault (circuit open/short/revise connection/over range) accrue, but the max. value will not exceed 10%FS.
      User can define the input/output when ordering, or program through PC;
