QA-I Current Isolator

QA-I

CURRENT ISOLATOR

3-way CURRENT ISOLATOR, ACTIVE or PASSIVE input/output, transparent to the analog signals 0-20mA/0-20mA, DIN rail mounting, universal supply AC/DC.


DESCRIPTION

The QA-I is a current isolator signals from 0 to 20mA. You don’t need to program the module, the device introducing a galvanic separation between input and output of 1.5kV, therefore the amount of input current will be made available at the output. The input and the output current can be ACTIVE or PASSIVE.


INPUT

CURRENT:
Active or Passive, up to 20 mA, input impedence 20 Ohm, max resolution 2μA.


OUTPUT

CURRENT:
Active or Passive, up to 20mA, maximum load resistence 600ohm.
 

LED INDICATION:

POWER: indicates the presence of power supply on the module.

FAIL: indicates the presence of a malfunction (hardware problem, over / under range, incorrect electrical connection.
 

MOUNTING INSTRUCTIONS:

to mount the card on DIN rail, we recommend to place the top of the form on the edge of the bar omega, then pushing the bottom until it clicks. The module is equipped with a slider fastening that will be pushed forward in order to ensure the perfect fastening of the module on the bar.
