o
Normal(DI=0)
- a falling edge (1 -> 0) of the Digital Input switches the
Relay Off;
o
Normal(DI=1)
- a rising edge (0 -> 1) of the Digital Input switches the Relay
On;
o
Inverse(DI=0)
- a falling edge (1 -> 0) of the Digital Input switches the
Relay On;
o
Inverse(DI=1)
- a rising edge (0 -> 1) of the Digital Input switches the Relay
Off.
AI+ No
- the number of the Analog Input (1 to 8) which is "attached" to this
Relay. If AI- No is set to zero, this is the single-ended input, otherwise
– the
(+) lead of the differential input.
AI- No
– if set to non-zero (1 to 8), this is the (-) lead of the differential input;
If
AI+ No
is non-zero and
AI- No
is zero, the Relay is controlled by the
AI+ No
measured value
.
If both
AI+ No
and
AI- No
are non-zero, the Relay is controlled by the
difference of
AI+ No
and
AI- No
measured values.
If
AI+ No
is zero, the Relay is not controlled by the Analog Input (in this case
the
AI- No
is not relevant).
AI Threshold 1
- the first level for controlling the Relay (range: from -9999 to
+9999);
AI Threshold 2
- the second level for controlling the Relay (range: from -9999
to +9999);
The Relay can be controlled in “normal” (Fig. 7.23) or “inverse” (Fig. 7.24)
mode depending on the Analog Input threshold values.
Figure 7.23.
Normal mode: AI Threshold 1 > AI Threshold 2
