Pepperl Fuchs KFA6-SR-2.3L.FA Data Sheet

Switch Amplifier

KFA6-SR-2.3L.FA

Features

• 2-channel

• 115/230 V AC supply

• 3-wire PNP/NPN sensor or push-pull input

• Relay contact output

• DIP switch selectable functions

• Minimum/maximum control

• Up to SIL 2 acc. to IEC 61508

Function

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

The device transfers the status of 2-wire and 3-wire sensors to
the relay contact output.

The device has 2 inputs and 2 relay contact outputs.

The device can be used either as dual channel signal
conditioner or as a two-point level controller.

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

A fault is signalized by LEDs.
