EN 50170/2 and IEC 61158-2;
31,25 kbit/s
• Up to 10 Ex devices can be
connected to the PA segment
• Supply via Power Rail
• 24 V DC rated operational voltage
• Removable terminals and Power
Rail
• EMC acc. to NAMUR NE 21
• Field circuit in the hazardous area
EEx ia IIC and Class I, Division 1,
Groups A, B, C and D
Together with the KLD2-GT-DP(R).xPA
Gateway, the Power-Link forms an SK2
Segment Coupler and can only be operat-
ed in association with it. The KLD2-PL-
Ex1.PA can be installed in Zone 2. The
Power-Link thus provides the intrinsically
safe interface. The PROFIBUS PA sta-
tions are supplied from the Power-Link via
the bus.
Data exchange between the Power-Link
and channel 1 of the KLD2-GT-
DP(R).xPA gateway takes place via the
power rail. If the Power-Link is operated
with channel 2, 3 or 4 of the gateway, a
wire connection for the data exchange
must be provided between the Power-Link
and the gateway, via the removable termi-
nals.
The communication of the SK2 segment
coupler behaves transparently. The Pow-
er-Link does not have to be configured.
The baud rate of the intrinsically safe
PROFIBUS PA segment is 31.25 kbit/s,
in accordance with IEC61158-2.
Please note!
Information on the commissioning of the
Profibus PA can be obtained from the
guidance documentation of the PROFI-
BUS User Organisation.
