The binary inputs contain interference suppression capacitors. In order to ensure EMC immunity, use the
terminals shown in the terminal diagrams/connection diagrams to connect the binary inputs to the common
potential.
7 For time-critical applications with low-active signals, consider the specified dropout times. If necessary, provide for active discharge of
the binary input (for example, a resistor in parallel to the binary input or using a change-over contact).
