Functional Safety KCD2-SCD-(Ex)1(.SP), HiC2031
Product Description
HiC2031
This isolated barrier is used for intrinsic safety applications.
The device repeats the input signal from a control system to drive HART I/P converters,
valve actuators, and displays located in a hazardous area.
Digital signals are superimposed on the analog values at the field side or control side
and are transferred bi-directionally.
An open field circuit presents a high impedance to the control side to allow alarm conditions
to be monitored by the control system.
This device mounts on a HiC termination board.
2.3
Interfaces
The device has the following interfaces.
•
Safety relevant interfaces: input I, output I
•
Non-safety relevant interfaces: none
The HART communication is not relevant for functional safety.
Note!
For corresponding connections see datasheet.
