Summary
  Pors-GPA series isolators receive current 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/100 load
   Operating temperature: -10~+70
   Insulation resistance: 100M /500VDC (between power, input, output, channel, communication)
   EMC: compliance to GB/T18268, IEC61326-1
   Power supply: DC24V10%
   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;

Form 1: input type
 

Code		Input signal					Input impedance
1		0~10mA					100
2		0~20mA
3		4~20mA
4		4~20mA					Power to transmitter  16~22VDC

 
Form 2: output type
 

Code		Output signal					Output impedance
1		0~5V					250
2		1~5V
3		0~10V					500
4		0~10mA					1K
5		0~20mA					500
6		4~20mA
