Overview
Modules with degree of protection IP67 cannot be used in areas
exposed to permanently high levels of humidity, in applications
with drilling emulsions and cutting oils or when cleaning with
high-pressure cleaners. The answer for these applications is
provided by the expansion of the K60 compact modules with the
K60R module with degree of protection IP68/IP69K.
The K60R modules are connected instead of the AS-Interface
flat cable using a round cable with M12 cable box.
The AS-Interface bus cable and the 24 V DC auxiliary voltage
supply are routed in this case in a shared round cable.
Degree of protection IP68 permits many new applications, which
were impossible with the former field modules with degree of
protection IP67. In applications such as filling plants or machine-
tools the K60R with degree of protection IP68 enables the mod-
ule to be used directly in zones exposed to permanent loading
by humidity. It is thus possible to make even more rigorous
savings in wiring with AS-Interface. The IP68 test conditions can
be found in the section "IP68/IP69K tests".
Cleaning with high-pressure cleaners, such as is regularly
performed in the food drinks industry for instance, is possible
without difficulty (IP69K).
In applications with tow chains, many users rely on placing the
AS-Interface bus cable in a round cable. With the K60R module
there is a round cable connection for direct connection to a
round cable. No adapter is required.
Mounting
The same mounting plates are used as for the K60 modules. In-
stead of using flat cables the K60R is connected using a 4-pole
round cable with an M12 connection. With the K60R the mount-
ing plate thus serves only as a fixture and ground terminal.
Addressing
Addressing is performed using the same socket as for the bus
connection. Connecting the module to the 3RK1 904-2AB01
addressing unit is performed using a standard M12 cable
(e.g. 3RX8 000-0GF32-1AB5). If the older version of the
3RK1 904-2AB00 addressing unit is used, a special addressing
cable (3RK1 901-3RA00) is required. When the mounting is fin-
ished, the module is connected with the addressing cable to the
addressing unit and addressed. The addressing cable is then
removed and the module connected to the bus cable.
Connection
K60R connection options
In the IP67 environment the service-proven standard compo-
nents are connected using flat cables. Spur lines are laid into the
IP68 environment by means of an AS-Interface M12 feeder
(3RK1 901-1NR..). The module is connected with a round cable
to an M12 cable box. For this purpose the module has an M12
bus connection instead of the former addressing socket. The
AS-Interface bus cable and the 24 V DC auxiliary voltage are
routed together in a 4-pole round cable. There must be no
ground conductor in this round cable. Connection to ground is
made through the mounting plate.
In the IP68 environment only cables with extruded M12 plugs
may be used. These cables are available preassembled as an
M12 cable plug/cable box version:
• 3RX8 000-0GF42-1AA6: 0.5 m long
• 3RX8 000-0GF42-1AB0: 1.0 m long
• 3RX8 000-0GF42-1AB5: 1.5 m long
To connect the distributor and the K60R module over long dis-
tances it is also possible to use freely configurable cables with
an M12 cable box and an open cable end, which are fitted with
an M12 plug (straight version: 3RX8 000-0CD45,
3RX8 000-0CE45 angle plug) and connected to the distributor.
This cable is available in two versions:
• 3RX8 000-0CB42-1AF0: 5 m long, with M12 cable box
• 3RX8 000-0CC42-1AF0: 5 m long, with M12 angle cable box
To connect more than one K60R module to one spur line,
the spur line can be split again using a T distributor
(3RK1 901-1TR00) with degree of protection IP68.
