Function

This signal conditioner is suitable for the connection of current and voltage signals and provides isolation for non-intrinsically safe applications.
The input ranges include 0 mA ... 20 mA, 0 V ... 10 V or 0 mV ... 60 mV. Subranges from the input ranges are selectable.
The output measuring signals are 0/4 mA ... 20 mA, 0/2 V ... 10 V or 0/1 V ... 5 V.
The output relay serves as trip value contact.
On the display the measured value can be indicated in various physical units.
The unit is easily programmed by the use of a keypad located on the front of the unit.
For additional information, refer to the manual and www.pepperl-fuchs.com.
