Overview
Modules with the degree of protection IP67 cannot be used in
environments with permanently high humidity, with drilling emul-
sions and cutting oils or for cleaning with high-pressure clean-
ers. For these applications, the extension for the K60 compact
modules, the K60R module with degree of protection IP68 /
IP69K, is the solution.
The K60R modules are connected via a round cable with a M12
cable plug instead of the AS-Interface ribbon cable.
The AS-Interface bus cable and 24 V DC auxiliary power are
routed in a common round cable.
The degree of protection IP68 permits many new areas of appli-
cations for which the previous field modules with degree of pro-
tection IP67 could not be used. The K60R with degree of protec-
tion IP68 makes it possible to use the module for applications
such as bottling plants or machine tools on-site in areas sub-
jected to permanently high humidity. This allows the savings in
wiring outlay due to AS-Interface to be implemented with even
greater consistency. For IP68 test conditions see Section
Tests IP68 / IP69K.
Cleaning with pressurized cleaning equipment, as is frequently
necessary in the food, beverages and tobacco industries, is
problem-free (IP69K).
When trailing cables are used, many users require that the AS-
Interface bus cable is routed in a round cable. The K60R module
permits direct connection to a round cable. An adapter is not re-
quired.

Design
Mounting
The same mounting plates are used as for the K60 modules.
The K60R is connected using a 4-conductor round cable with an
M12 connection instead of using ribbon cables. The mounting
plate therefore only serves for the K60R as a mounting point and
grounding connection.
Addressing
Addressing is carried out using the same socket as for the bus
connection. The connection of the module to the addressing unit
3RK1 904-2AB01 is carried out with a standard M12 cable
(e.g. 3RX1 642). A special addressing line (3RK1901-3RA00) is
required when using the older version of the addressing unit
3RK1 904-2AB00. Following mounting, the module is connected
to the addressing unit using the addressing line, and then
addressed. The addressing line is subsequently removed, and
the module connected to the bus cable.
