Details: KFD2-GS-1.2W


This signal conditioner provides the galvanic isolation beetween field circuits and control circuits.

The device is a trip amplifier with two trip points. Trip points, hysteresis and mode of operation can be set independently for both relay outputs.

0/4 mA ... 20 mA-, 0/1 V ... 5 V- or 0/2 V ... 10 V signals can be connected at the input.

The device actuates the relay output when it reaches the adjusted trip points.

The device is easily configured by the use of DIP switches and potentiometers.
