2.1 Function
General
The device supplies 2-wire and 3-wire transmitters, and can also be used with
current sources.
Two relays and an active 0/4 mA to 20 mA current source are available as
outputs. The relay contacts and the current output can be integrated in security-
relevant circuits. The current output is easily scaled.
On the display the measured value can be indicated in various physical units.
The device is easily configured by the use of keypad or with the PACTware
configuration software.
The input has a line fault detection.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
KFD2-CRG2-1.D
This signal conditioner provides the galvanic isolation between field circuits and
control circuits.
The device is supplied by a voltage of 20 V DC to 30 V DC via Power Rail or
terminals.
A fault is signalized by LEDs and a separate collective error message output.
KFD2-CRG2-Ex1.D
This isolated barrier is used for intrinsic safety applications.
The device is supplied by a voltage of 20 V DC to 30 V DC via Power Rail or
terminals.
A fault is signalized by LEDs and a separate collective error message output.
KFU8-CRG2-1.D
This signal conditioner provides the galvanic isolation between field circuits and
control circuits.
The device is supplied by a voltage of 20 V DC to 90 V DC or
48 V AC to 253 V AC via terminals.
A fault is signalized by LEDs.
