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	1

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 DC 24 V	C79451-A3260-A4

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.
