Table 19: Technical data – digital inputs – “5V area”
Warning!
Voltages greater than 9 V DC can lead to overheating and the defect of
components.
The inputs are designed exclusively for direct voltages (DC). AC
voltages must not be connected.
The light emitting diodes signal the high state (logic "1") of the input at rated voltage. In the
transition ranges between guaranteed low and high levels, the LED is not meaningful.
