According to IEC 61131-2.
3)
The specified values are the switching voltage supplied by the device. If higher voltages are impressed
externally, the maximum value of 2.0 V can be exceeded.
4)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers,
make sure that the test pulses do not result in deactivation when using the above parameters.
5)
Limit the cable length to the specified values to ensure that the protective device functions correctly, par‐
ticularly that a cross-circuit between the outputs is safely detected. (Also observe IEC 60204-1.) The
specified values apply to the total resistance of each wire including contact and connector resistances.
