2 Product Description

2.1 Function

General

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

The de-energized to safe (DTS) function is permitted for SIL 3 and PL e applications.

An internal fault or a line fault is signalized by the impedance change of the relay contact input
and an additional relay contact output.

A fault is signalized by LEDs and a separate collective error message output.

The output must be protected against contact welding by an internal fuse or an external current
limitation.

KFD2-RSH-1.2D.FL2

The device is a relay module that is suitable for safely switching applications of a load circuit.
The device isolates load circuits up to 60 V DC and the 24 V DC control circuit.

KFD2-RSH-1.2D.FL3

The device is a relay module that is suitable for safely switching applications of a load circuit.
The device isolates load circuits up to 230 V AC and the 24 V DC control circuit.

2.2 Interfaces

The device has the following interfaces:

• Safety-relevant interfaces: input, output (DTS)

• Non-safety relevant interfaces: fault indication output
