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 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.
The 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.
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 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
AS-Interface Specification 2.1, 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 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.
