Overview
Digital I/O modules, IP67 - K20
的K20 compact module series rounds off the AS-Interface
compact modules with a particularly slim design and a width of
a mere 20 mm. Thanks to its extremely compact dimensions,
these modules are particularly suited for handling machine
applications in the field of production engineering where mod-
ules need to be arranged in the smallest of spaces.
Robotics is yet another application area. Instead of the
AS-Interface flat cable, the K20 modules are connected to
AS-Interface over a round cable with M12 cable box.
的AS-Interface bus cable and the 24 V DC auxiliary power
supply are routed in this case in a shared round cable.
This enables extremely compact installation.
的flexibility of the round cable means that it can also be used

ules are also ideal for such applications as their non-encapsu-
lated design makes them particularly light in weight.
In applications with tow chains, many users rely on placing the
AS-Interface bus cable in a round cable. In this case, the K20
modules support direct connection to the round cable. No flat to
round cable adapter is required.
的K20 compact module series includes standard AS-Interface
modules, as well as an ASIsafe version for the connection of
safety-related sensors, such as EMERGENCY-STOP push-
buttons or protective door monitoring. All standard AS-Interface
K20 modules support, as far as technically possible, the
expanded address mode (A/B addresses) according to

stations to an AS-Interface network. The K20 module with four
inputs and four outputs works in expanded address mode ac-
cording to AS-Interface specification 3.0 which, for the first time,
supports four outputs with an A/B slave, thus enabling 248 in-
puts and 248 outputs in a fully expanded AS-Interface network.
For particularly space-saving dimensions, the sensors and actu-
ators are connected over M8 plug-in connectors. Alternatively,
M12 connectors with Y assignment can be used.
