Table 4.4-4 Threshold voltage of picking-up / dropping-off for binary inputs
(a) In the case of DC rated voltage "110-250 Vdc"
Voltage level
High
Low
(b) In the case of DC rated voltage "24-60 Vdc"
Voltage level
High
Low
As the threshold voltage is expressed with Table 4.4-4, the user should set High or Low to
match to the voltage value to input to binary inputs. Table 4.4-5 shows the recommended
settings.
This matter means that the user should also set a threshold voltage at the power supply unit
to determine the degree of the power failure (see
module
).
