135U/155U central controller

Application The 135U/155U central conĆ

troller can be used optionally

for the construction of a

S5Ć135U, S5Ć155U or

S5Ć155H programmable conĆ

troller.

Two 135/155U central controlĆ

lers are required for a

S5Ć155H programmable conĆ

troller.

Design The 135U/155U central conĆ

troller comprises:

 21 free slots

 1 power supply chassis with

builtĆin fan

S5-135U, S5-155U

Depending on the extent of

the automation task, the cenĆ

tral controller can be

equipped with the following

CPUs:

 CPU 948 (max. 4)

 CPU 928B (max. 4)

 CPU 928 (max. 4)

 CPU 922 (max. 4)

All CPUs can also operate

jointly in multiprocessor

mode. When more than one of

these central modules is used

a 923A/923C coordinator is

required (see page 4/30).

S5-155H

One CPU 948R can be used

per central controller.

Power supply chassis

 Redundant twoĆoutĆofĆthree

fan concept;

Should one fan cease operĆ

ating the speed of the other

fans is increased thus enabĆ

ling the programmable conĆ

troller to continue operation.

The defective fan can be reĆ

placed while the controller is

in operation

 Redundant oneĆoutĆofĆtwo

battery concept;

In the case of a failure of the

main battery (Li battery) the

accu battery switches on

automatically for a period of

three weeks

 Mains buffering to NAMUR:

20 ms
