Table 13: Technical data - digital inputs - “24V area”
Warning!
Voltages greater than 30 V DC can lead to overheating and the defect
of components.
The inputs are designed for DC voltages only. Do not connect
alternating voltages - AC.
The LEDs indicate the high state (logic "1") of the input at nominal voltage. In the transition
areas between guaranteed low and high levels, the LED is not meaningful.
