Description
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

measuring value/**0 load
Operating temperature: **0~**0
Insulation resistance: **0M /**0VDC (between
power, input, output, channel, communication)
EMC: compliance to GB/T****8, IEC******1
Power supply: DC*4V*0%
Power consumption: < 1W (1 in 1 out)

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 *0%FS.
User can define the input/output when ordering;
