Pepperl Fuchs KFD0-RO-Ex2 Datasheet

Relay Module

KFD0-RO-Ex2

<2-channel isolated barrier

<24 V DC supply (loop powered)

<Logic input 15 V DC ... 30 V DC, non-polarized

<Relay contact output

<Up to SIL 3 acc. to IEC 61508

Function

This isolated barrier is used for intrinsic safety applications.

The device switches intrinsically safe circuits on the field side. Typical applications for the use of the device are remote reset, fire alarm testing or remote calibration of strain gauges.

The outputs are galvanically isolated to the inputs. The inputs are not polarized and share a common reference potential. Each input of the device is protected by a fuse and an electronic current limiting.
