Introduction

1 Introduction
1.1

General Information

This manual contains information on using the device in control circuits that are
related to functional safety.
The corresponding data sheets, the operating instructions, the system
description, the declaration of conformity, the EC-Type Examination Certificate,
and the applicable certificates (see data sheet) are an integral part of this
document.
The stated documents are available at www.pepperl-fuchs.com or from your
local Pepperl+Fuchs representative.
Mounting, installation, commissioning, operation, maintenance and disassembly
of any devices may only be carried out by trained, qualified personnel. The
instruction manual must be read and understood.
In the event of a device fault, the devices must be taken out of operation and
measures must be taken to protect them against unintentional startup. Devices
may be repaired only by the manufacturer. Deactivating or bypassing safety
functions, or failing to observe the instructions in this manual (which lead to faults
or affect the safety functions), can damage property and the environment or
cause personal injury, for which Pepperl+Fuchs GmbH accepts no liability.
The devices have been developed, manufactured, and tested according to the
applicable safety standards. The devices may be used only for the applications
described in the instructions under the specified ambient conditions and
exclusively in connection with the approved peripherals.

Intended Use

General
The devices are single devices for DIN rail mounting.
KFD0-RSH-1(-Y2)
These signal conditioners provides the galvanic isolation between field circuits
and control circuits.
The devices are relay modules that are suitable for safely switching applications
of a load circuit. The devices isolate load circuits up to 230 V and the 24 V control
interface.
The devices can also be used as interfaces in output loops for ESD (Emergency
Shut Down) systems classified as SIL3. The safe state in this application is de-
energized to safe. The output has three relays that are of diverse design, but have
a common effect on the output. An additional fuse in series to the relay contacts is
available.
The KFD0-RSH-1-Y2 is protected against high pulses during OFF state, low
pulses during ON state and a load impedance check.
