P+F isolated barrier Transmitter Power Supply KFU8-CRG2-Ex1.D 1-channel Analog input
Features
• 1-channel isolated barrier
• Universal usage at different power supplies
• Input 2-wire and 3-wire transmitters and 2-wire current
sources
• Output 0/4 mA ... 20 mA
• 2 relay contact outputs

Function
This isolated barrier is used for intrinsic safety applications.
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 ... 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.
A fault is signalized by LEDs acc. to NAMUR NE44.
