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.
