2.5.2 Binary Signal Inputs
Threshold pickup and drop-off points as per ordering option
●
18 V standard variant (V
A,nom
: = 24 to 250 V DC):
■
Switching threshold in the range 14 V to 19 V.
Special variants with switching thresholds from 58% to 72% of the nominal input
voltage (i.e. definitively “low” for V
A
< 58% of the nominal supply voltage,
definitively “high” for V
A
> 72% of the nominal supply voltage).
●
Special variant 72 V: Nominal supply voltage 110 V DC.
●
Special variant 83 V: Nominal supply voltage 127 V DC.
●
Special variant 143 V: Nominal supply voltage 220 V DC.
●
Special variant 163 V: Nominal supply voltage 250 V DC.
Power consumption per input
●
18 V standard variant:
V
A
= 19 to 110 V DC : 0.5 W ± 30%,
V
A
> 110 V DC: V
A
·5 mA ± 30%.
●
Special variants:
V
A
> switching threshold: V
A
·5 mA ± 30%.
The standard variant of binary signal inputs (opto couplers) is recommended in
most applications, as these inputs operate with any voltage from 19 V. Special
versions with higher pick-up/drop-off thresholds are provided for applications where
a higher switching threshold is expressly required.
The maximum voltage permitted for all binary signal inputs is 300 V DC.
