Function

Together with the KLD2-GT-DP(R).xPA
Gateway, the Power-Link forms an SK2
Segment Coupler and can only be operat­ed in association with it. The KLD2-PL­Ex1.PA can be installed in Zone 2. The
Power-Link thus provides the intrinsically
safe interface. The PROFIBUS PA sta­tions are supplied from the Power-Link via
the bus.
Data exchange between the Power-Link
and channel 1 of the KLD2-GT­DP(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 termi­nals.
The communication of the SK2 segment
coupler behaves transparently. The Pow­er-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.
