Table 3. Input types
NO input
NC input
NO input can be in normal or in triggered state. In
normal state C
A
contacts are opened. Input
triggering is caused by C
A
contacts closing.
NC input can be in normal or in triggered state. In
normal state C
A
contacts are closed. Input triggering
is caused by C
A
contacts opening.
3EOL/DW/NO input
3EOL/DW/NC input
3EOL/DW/NO input is operated in such way that C
A
contacts closing is interpreted as triggering of the
first input while C
B
closing is interpreted as
triggering of the second input. In VISO software DW
input type is represented by two independent inputs.
Each can be used for different purpose and
assigned with different function.

Parametric resistors
The same values of parametric resistors are used for all inputs i.e. 1kΩ; 1,2kΩ; 1,5kΩ; 1,8kΩ; 2,2kΩ; 2,7kΩ;
3,3kΩ; 3,9kΩ; 4,7kΩ; 5,6kΩ; 6,8kΩ; 8,2kΩ; 10kΩ; 12kΩ. In case of 3EOL/DW (Double Wiring) input type,
Alarm A resistor defines a value of resistor used to detect triggering of the first input while Alarm B resistor
defines a value of resistor used to detect triggering of the second input. Alarm A resistor value must differ
from value of Alarm B resistor at least by three positions in the list above. Total resistance of wire used to
connect contacts to input should not e
xceed 100 Ω. Default values of parametric resistors:
