Overview
K60 analog compact module
AS-Interface analog modules from the K60 compact series
detect or issue analog signals locally. These modules are linked
to the higher-level controller through an AS-Interface master
according to Specification V2.1 or Specification V3.0.
The analog modules are divided into the following groups:
•
Input modules
- for sensors with current signal
- for sensors with voltage signal
- for sensors with thermal resistor
•
Output modules
- for current actuators
- for voltage actuators
The input modules according to profile 7.3/7.4 are available with
two or four input channels. It is possible in addition to convert the
two-channel module to using only one input channel, thus en-
abling very short times before the analog value is available. The
conversion is effected by means of a jumper plug at socket 3.
The transmission times achieved with analog modules accord-
ing to Profile 7.A.9 are shorter by half than those achieved with
Profile 7.3/7.4. Operation is adjustable in this case, e.g. it is pos-
sible to choose with the ID1 code whether the module is oper-
ated with one or two channels.
The output modules are configured as two-channel modules as
standard.
The input and output channels are electrically separated from
the AS-Interface network. If sensors with a higher power require-
ment are to be connected, more power can be supplied through
the auxiliary voltage as an alternative to the internal supply.
In the manual "AS-Interface Analog Modules Profile 7.3, Profile
7.A.9", the modules are presented in great detail along with their
technical specifications and in-depth notes on operation.

Benefits
•
Analog modules are just as easy to integrate in AS-Interface
as digital modules
•
Analog values can be easily detected and issued locally
•
Preprocessing of the analog value transfer in the master
enables rapid evaluation of the analog values
•
Up to four values can be detected using one analog module
•
Faster transmission and conversion of analog values thanks to
the new option for switching to single-channel operation
In addition, Specification V3.0 now also offers:
•
A/B technology, now also with analog modules
•
On average, double fast transmission times (only 3 or 4 cycles,
depending on the resolution selected)
•
Variable adjustable mode: 12-bit or 14-bit resolution, single-
channel or two-channel, selectable via the ID1 code
•
Additionally simplified handling of analog value processing
with Specification V3.0 masters, the DP/AS-i LINK Advanced
