3.2 Ex ia entity systems
The BA414DF-F Fieldbus Indicator has Ex ia
certification with entity parameters for applications
in Zone 0, 1 and 2.

The BA414DF-F Fieldbus Indicator may be
connected to any intrinsically safe segment
providing:

The device powering the fieldbus segment is
ATEX Ex ia certified for Zone 0, 1 or 2
applications, or Ex ib certified for application
in Zone 1 or 2, or Ex ic certified for
applications in Zone 2. The output
parameters of the segment should be equal
to or less than:

Uo = 22V dc
Io = 250mA dc
Po = 1.2W

The segment can provide an additional 13mA
to power the Fieldbus Indicator.

The equivalent capacitance Ci of the
