Overview
Digital I/O modules, IP67 - K20
The K20 compact module series rounds off the AS-Interface
compact modules with a particularly slim design and only
20-mm width. Thanks to its extremely compact dimensions,
these modules are particularly suited for handling machine ap-
plications in the field of production engineering where modules
need to be arranged in the smallest of spaces.
Robotics is yet another application area. The K20 modules are
connected to the AS-Interface with a round cable with M12 cable
box instead of with the AS-Interface flat cable. The AS-Interface
bus cable and the 24 V DC auxiliary energy are routed in this
case in a shared round cable. This enables extremely compact
installation.
The flexibility of the round cable means that it can also be used
on moving machine parts without any problems. The K20 mod-
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.
The K20 compact module range includes standard AS-Interface
modules, as well as an ASIsafe version for the connection of
safety-related sensors, such as EMERGENCY-STOP pushbut-
tons 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
AS-Interface Specification V2.1, which enables connection of
62 stations to an AS-Interface network. The K20 module with four
inputs and four outputs works in expanded address mode
according to AS-Interface Specification V3.0 which, for the first
time, supports four outputs with an A/B slave, thus enabling
248 inputs 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.
