ES 100 K extension system
ES 100 K extension system
Up to eight ES 100 K extension systems can be connected in
order to supplement the 6 I/O module slots in the AS 235 K
system (max. 4 systems per I/O bus). Extension of the AS 235
system by the ES 100 K extension system is also possible.
Each ES 100 K system has space for 13 I/O modules. The num-
ber of I/O modules per AS 235 K automation system can there-
fore be extended to 108 (104 slots in the ES 100 K + 4 slots in
the AS 235 K).
The extension systems can be connected with a cascade or
radial configuration. The total cable length must not exceed
500 m.
An interface module 6DS1322-8AA is required for the coupling
in both the basic system and the extension system. The interface
module can be inserted into any slot for I/O modules in the
AS 235 K and ES 100 K systems. Slot 1 should be preferably
used, however.
The ES 100 K extension system is available for AC 230 V and
DC 24 V. It consists of:
• ES 902 subrack, 15 U high
– For AC 230 V C79451-A3260-A3
– For DC 24 V C79451-A3260-A4
each with
power supply subrack,
13 slots for I/O modules,
process connection panel for I/O modules,
power supply system,
cable clamping rail with 10 clamps
• Power supply module SV1
For ES 100 K with AC 230 V
– AC 230 V / DC 24 V C79451-A3260-A20
For ES 100 K with DC 24 V
– DC 24 V C79451-A3260-A25
• Interface module for ES 100 K 6DS1 322-8AA
The subrack corresponds to the ES 902 packaging system and
is 15
U high. It contains slots for the power supply module, an
alarm logic module, and the interface module for ES 100 K and
13 I/O modules.
The subrack also contains a process connection panel with
576 pins 2.4 mm x 0.8 mm in the Maxi-Termi-Point system.
A power supply module is required for the extension system
depending on the selected supply voltage of the ES 100 K:
• C79451-A3260-A20 (AC 230 V) or
• C79451-A3260-A25 (DC 24 V).
The same power supply modules are also used in the AS 235 K
system.
The alarm logic module 6DS1 901-8AA can the ordered as an
optional accessory. It monitors the 24-V voltages L+ and PM, the
optionally used signal inputs for temperature monitoring, door
contact, fan contact and spare contact, e.g. if the ES 100 K
extension system is installed in a TELEPERM M standard cabinet
and if cabinet messages are to be detected or cabinet alarm
lamps are to be triggered.
An alarm detected in the ES 100 K system is not transmitted to
the central processing unit of an AS 235 K automation system,
however. Therefore it does not lead to the output of an alarm text
on the process monitor.
Interface module for ES 100 K
The interface module for ES 100 K links the I/O bus of the
AS 235 K basic system to the I/O bus of the ES 100 K extension
system via a cable.
Interface modules for ES 100 K are required in the AS 235 K
basic system and in the ES 100 K extension system.
The interface module inserted in the ES 100 K provides the
DC 5 V supply required for the I/O bus.
I/O modules
Slots for up to 13 I/O modules are present in the ES 100 K
extension system. In addition to the I/O modules of the
TELEPERM M process control system, certain I/O modules of
the TELEPERM ME process control system can also be used in
the ES 100 K system.
Depending on the addressing volume of the I/O bus, up to eight
ES 100 K extension systems with a total of 104 I/O modules can
be operated with one AS 235 K system.
See Section 4 for the properties, functions and Ordering data of
the I/O modules.
