An ’Ex’ repeater power supply unit must be used.
For calculation of the supply voltage the same applies as for the
standard non-’Ex’ version.
The connected Ex repeater must be HART®-compatible so that
it can be operated with the PCSTAR2 communication software or
the HART® communicator.
The HART adapter should be connected to the intrinsically safe
input of the Ex repeater!
The units with plastic coating can only be used in IIB gas class
hazardous area.
