DSTD 197 (replacing DSTD W120)
A connection unit with inputs for 100 V - 120 V a.c./d.c. The connection unit contains eight
independent channels. The inputs are galvanically isolated from the electronics.
With connection distances greater than approximately 200 m, with an a.c. supply, the capacitive
cross-talk can result in malfunctioning. Consider the technical data of the cable type concerned
in relation to the input impedance of the board and switch-over levels. The connection unit is
supplied with an external 24 V voltage.
DSTD 198 (replacing DSTD W130)
A connection unit with inputs for 230 V a.c. The connection unit contains eight independent
channels. The inputs are galvanically isolated from the electronics. With connection distances
greater than approximately 200 m, with an a.c. supply, the capacitive cross-talk can result in
malfunctioning. Consider the technical data of the cable type concerned in relation to the input
impedance of the board and switch-over levels. The connection unit is supplied with an external
24 V voltage.
DSDI 110A/DSDI 110AV1
DSTD 145, DSTD 147, DSTD 148, DSTK 226L5
These variants of connection units provide object oriented connection to DSDI 110A and
DSDO 110. The general feature of DSDI 110A are: Thirty-two scanned or interrupt- controlled
digital inputs. Pulse catching can be configured. The properties of the inputs (for example, 24 V
d.c., 120 V a.c., 230 V a.c.) are decided by the selected connection unit.
Different sets of I/O boards and connection units are offered to match various object types
requiring different input voltages and number of inputs per object.
DSDI 120A
DSTD 150A / DSTD 190, DSTK 221L3
DSDI 120AV1, DSTD 150A/DSTD 190V1
DSTK 221L3
Scanned or interrupt-controlled 48 V d.c. inputs, otherwise similar to
DSDI 110A/DSDI 110AV1.

Advant Controller 450 can be equipped with digital outputs of static type (semiconductor) and
with a relay contact. The different output types have partially different properties.
Certain significant properties are presented below:
• Static outputs
These generally have a long service life, even with a high frequency of change.
• Relay outputs
These have a shorter service life than static outputs. When the output is frequently
changed, it is subject to wear and its service life is shortened. They can withstand
occasional higher voltage. Different system voltages can be accommodated on the same
board. A certain degree of inductive load can be accepted. Small load currents with low
voltage (<40 V) can give contact problems.
In the control of two-phase motors (with a phase-displacing capacitor between the forward and
reverse windings), a reverse voltage considerably higher than the system voltage can be induced
