There are certain restrictions in number of I/O subracks, number of I/O boards and number of
signals of different categories. Please see Section 3.2, Technical Data Including Capacity &
Performance.
There are no restrictions on location and mixing of boards of different categories in an I/O
subrack. There are, however, some production rules to facilitate ordering and rapid delivery.
See Section 2.1.4, Standard Layout and Disposition of Cabinets.
When you design a control system, it is desirable to leave some spare capacity. It is practical to
have approximately 10% to 20% of the channels as spares. The same recommendation is valid
for spare space in subracks.
You can add new I/O boards on-line provided there are spare items in the data base. Reflect the
need when you make the data base dimensioning.

General
With current signals and series coupling of loads, the total resistance may not exceed the
resistance through which the sensor output can be driven.
The referred type designations below are valid to circuit board, connection unit and internal
cable, respectively.
DSAI 130
DSTA 131, DSTK 221L3
DSAI 130A
DSTA 131, DSTK 227L3
Differential inputs for applications with considerable accuracy requirement. Common Mode
Voltage up to 100 V (50 V DSAI 130A) is acceptable. These are used when it is necessary to
ground measurement circuits at different places in the system. This means you can use
transducers which require grounding of the signal zero. Fusing occurs in groups at six fuses
which can be used for an optional number of channels.
DSAI 130
DSTA133, DSTK 221L3
DSAI 130A
DSTA 135, DSTK 221L3
16 differential wit individually power limit transducer power supply for applications with
considerable accuracy requirements. Common Mode Voltage up to 100V (50V DSAI 130A) is
acceptable.
DSAI 130
DSTA 137, DSTK 221L5
DSTA 137 provides object oriented connection to DSAI 130 and DSAO 130. Regarding input
features please refer to DSAI 130 using DSTA 131 above. No fusing of power supply
distribution. However, individual protection per channel is available by means of a PTC resistor.
