Description

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;
