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;
