DSAI 130A
DSTA 138, DSTK 221L5
DSTA 138 provides object oriented connection to DSAI 130A and DSAO 130A. Regarding
input features please refer to DSAI 130A using DSTA 131 above. No fusing of power supply
distribution. However, individual protection per channel is available by means of a PTC resistor.
DSAI 133

32 single ended and unipolar current inputs, which means that the transducers or their power
supply can be grounded only within a geographically limited area, where the ground potential is
the same as the system ground.
127(
There are two connection units due to the number of input channels.
In a redundant configuration two DSAI 133 can be connected to the same connection units.
The redundant inputs are handled by the application programmer in the same way as the other
analog inputs.
DSAI 146
DSTA 145, DSTK 229SL3
A design for three-wire connected Pt 100 transducers, which compensates for the length of lead,
provided that the lead resistance is the same for the cable conductors.
A conductor break in a transducer does not affect other measurement channels.
DSAI 155A
DSTA 156, DSTK 160
Used for grounded thermoelements. Earth the channels not connected to transducers.
NOTE
You can use only one type of thermoelement per board.
DSAI 155A
DSTA 156B, DSTK 225SL3
Used for JURXQGHGand QRQJURXQGHG thermo elements. Earth channels to which transducers
are not connected.
DSTA 155, DSTA 155P
Placed out in the process to minimize the length of expensive compensation cable from
thermoelements. The unit measures the temperature at the cold junction. Locate it at a place
with small temperature variations and, naturally, at a place conveniently located with respect to
all of the transducers connected to the board concerned.
DSTA 155P has pluggable screw terminals.
