Product Description
2.1
Function
General
The device supplies 2-wire transmitters in the hazardous area, and can also be
used with current sources.
It transfers the analog input signal to the safe area as two isolated output signals.
Bi-directional communication is supported for SMART transmitters that use
current modulation and voltage modulation for the information transfer.
The output is selected as a current source, current sink, or voltage source via
switches.
HiC2027**
This isolated barrier is used for intrinsic safety applications.
This device mounts on a HiC Termination Board.
KCD2-STC-1.2O
This signal conditioner provides the galvanic isolation between field circuits and
control circuits.
Test sockets for the connection of HART communicators are integrated into the
terminals of the device.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
KCD2-STC-Ex1.2O.**
