1. Summary
Pors-GK series isolators can receive signal of
passive switch contact or proximity sensor, then isolate the signal
and transmit it to control system or other instruments. There is
relay contact output and transistor output for options; and
function of circuit fault detection can be selected;
Power, input, output are isolated from each
other, two channels are isolated and independent.
2. Technical index
Input
Type: switch or NAMUR proximity
sensor (compliance with DIN****4)
Open-circuit voltage: 8V0.5V
Switch threshold: 1.5mA
Hysteresis: 0.2~0.4mA
Circuit fault: broken-circuit current:
(when with *4VDC power, relay contact close)
Input output properties
When delivery input and output are in phase,
that is when input switch pick up, output reply pick up (transistor
is on) as well. Switch\'s State indictor in the panel will
light.
Performance index (to full span)
Isolated strength: 2.5kVAC, *0Hz, 1min
Insulation resistance: **0M /**0VDC
EMC: compliance to GB/T****8, IEC******1
Operating temperature: **0~**0
Operating humidity: 0~*0%RH (no dew)
Circuit fault detection (LFD)
Indicators (, ) are double color LED indicator
for switch state. Yellow: output state; Red: input loop fault;
Note: when with circuit fault detection, if the
input is switch contact, shunt reistors have to be connected, in
case that normal open and close of the switch will be judged as
open and short of the input loop wrongly.
Explanation of LED indicators (example: relay output)
When power on and power is normal, indicator
"Pwr" is red;
1) when circuit fault detection is valid,
, indicators are Red, that is input loop is faulty and outupt relay
is not pickup;
2) , indicator is yellow, that is outupt
relay is pickup, and ther is not fault in input loop;
3) if , indicator light with double color
(Red and Yellow), that is relay contact is pickup, and there is
fault in input loop;
