The AS-Interface modules in the compact range are characterized by opti-
mized operating features and improved user-friendliness.
This can reduce mounting and commissioning times for AS-Interface by up
to 40%. Additional LEDs provide information on the most important operat-
ing modes of the module, resulting in a considerable increase in system
availability.
The modules of the compact range consist of two components:
Mounting plate and compact module
The mounting plate mechanically fixes the AS-Interface profile cables, takes
the compact module, and serves as a template with drill holes.
The compact module contains the electronic components for communica-
tion and the M12 standard connections for inputs/outputs. Up to four sen-
sors and four actuators can be easily and reliably connected to the compact
module using the M12 standard connection.
The mounting plate and compact module are only connected to each other
by means of a single screw. Contact is established with the AS-Interface
cable by means of the proven insulation displacement method.
AS-Interface modules in the compact range that have an M12 connection
can have a protective conductor (PE) connected to them.
Using an addressing socket integrated in the compact module, you can also
allocate addresses when the module is in place.
The design of the analog modules has been adapted for the compact mod-
ules. The analog input and output modules each have two channels. You can
connect measuring sensors and analog actuators using standard M12 con-
nectors. The following groups of analog modules exist:
• Input module for two current sensors
• Input module for two voltage sensors
• Input module for two thermal resistors
• Output module for two current actuators
• Output module for two voltage actuators
All the measured values - except for the thermal resistance value of Pt 100
(not linear) - are available in linear form. In other words, the non-linear trans-
mission curve of the thermal resistor sensor is automatically linearized in
the analog module, and measured values can be processed directly in the
programmable controller.
The input and output channels are isolated. Two-wire and four-wire sensors
can be connected. Differential inputs produce considerable suppression of
common-mode interference. The integrating sigma-delta converter ensures
high measurement accuracy.
