Function: KFU8-VCR-1

This signal conditioner provides the isolation for non-intrinsically safe applications.

The device supplies 2-wire and 3-wire transmitters, and can also be used with current and voltage sources.

The input ranges include 0/4 mA ... 20 mA or 0/2 V ... 10 V.

At the output the signal is available as 0/4 mA ... 20 mA or 0/2 V ... 10 V.

Output and measuring range are selected by switches located on the front of the device.
