We sell Pepperl+Fuchs switch amplifier KFD2-SH-Ex1.T.

Time: 2020年08月07日

Switch amplifier KFD2-SH-Ex1.T: 1-channel isolated barrier. 24 V DC supply. Input for approved dry contacts or SN/S1N sensors. Active voltage output. Relay contact output. Fault indication output. Line fault detection (LFD). Up to SIL 3 acc. to IEC 61508. Up to PL d acc. to EN/ISO 13849.


This isolated barrier is used for intrinsic safety applications.

The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from a hazardous area to a safe area.

The input controls one active voltage output and one relay contact output with a NO contact.

Unlike an SN/S1N series proximity sensor, a mechanical contact requires a 10 kΩ resistor to be placed across the contact in addition to a 1.5 kΩ resistor in series.

Lead breakage (LB) and short circuit (SC) conditions of the control circuit are continuously monitored.

During an fault condition, the fault indication output and the outputs I and II de-energize.

For safety applications up to SIL3, output I must be used. For safety applications up to SIL2, output I and output II can be used.
