Table 980: Binary inputs
Description Value
Operating range ±20% of the rated voltage
Rated voltage 24...250 V DC
Current drain 1.6...1.9 mA
Power consumption 31.0...570.0 mW
Threshold voltage 16...176 V DC
Reaction time <3 ms
Adjust the binary input threshold voltage correctly. The threshold voltage
should be set to 70% of the nominal auxiliary voltage. The factory default
is 16 V to ensure the binary inputs’ operation regardless of the auxiliary
voltage used (24, 48, 60, 110, 125, 220 or 250 V DC). However, the
default value is not optimal for the higher auxiliary voltages. The binary
input threshold voltage should be set as high as possible to prevent any
inadvertent activation of the binary inputs due to possible external
disturbances. At the same time, the threshold should be set so that the
correct operation is not jeopardized in case of undervoltage of the
auxiliary voltage.
