7NG3092-8AW

3.7.1 Application and use

It serves in devices with the ordering designation 7NG3242-0***0 as a measuring

set for:

• voltage measurement in the measuring range: -1.2 to 10 V DC or

• current measurement in the measuring range: -12 to 100 mA DC

The basic accuracy of the U/I input plug is: 0,1 %.

The minimum span is for:

• voltage measurement (measuring range -1.2 to 10 V): 0.05 V

• current measurement (measuring range -12 to 100 mA): 0.41 mA

WARNING

The U/I input plug may not be used in hazardous (explosive) areas.
