Temperature Converter with Trip
Values	2
KFD2-GUT-Ex1.D

<1-channel isolated barrier

<24 V DC supply (Power Rail)

<Thermocouple, RTD, potentiometer or voltage input

<Redundant TC input

<Current output 0/4 mA ... 20 mA

<2 relay contact outputs

<Configurable by PACTware or keypad

<Line fault (LFD) and sensor burnout detection

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

Function

This isolated barrier is used for intrinsic safety applications.

The device converts the signal of a resistance thermometer, thermocouple, potentiometer, or voltage source to a proportional output current. It also provides a relay trip value.

The removable terminal block K-CJC-** is available as an accessory for internal cold junction compensation of thermocouples. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.

The device is easily configured by the use of the PACTware configuration software. For additional information, refer to the manual and www.pepperl-fuchs.com.
