Frequency Converter with Trip Values KFD2-UFC-Ex1.D

1-channel isolated barrier

24 V DC supply (Power Rail)

Input for NAMUR sensors or dry contacts

Input frequency 1 mHz ... 5 kHz

Current output 0/4 mA ... 20 mA

Relay contact and transistor output

Start-up override

Line fault detection (LFD)

Up to SIL 2 acc. to IEC 61508/IEC 61511

Function :

This isolated barrier is used for intrinsic safety applications. The device is a universal frequency converter that changes a

digital input signal into a proportional free adjustable 0/4 mA ... 20 mA analog output signal and functions as a

switch amplifier and a trip alarm. The functions of the switch outputs (2 relay outputs and 1 potential free transistor output)

are easily adjustable [trip value display (min/max alarm),

serially switched output, pulse divider output, error signal output]. The device is easily configured by the use of keypad

or with the PACTware configuration software.

A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
