Applies to the voltage range between -30 V and +30 V.

According to IEC 61131-2.
3)
The specified values are the switching voltage supplied by the safety light curtain. 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 individual conductor resistance to the specified values to ensure that the light curtain func‐
tions correctly, particularly 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 resis‐
tances.
6)
If a T distributor is used, the specified values apply to the resistance of the entire cable from the system
connection of the device to the connection in the control cabinet.
For a cascade, the specified values apply to the resistance of the entire cable from the system connec‐
tion of the last guest device to the connection in the control cabinet.
7)
The supply cable must not be used to connect other loads with the exception of the senders.
8)
If a T distributor is used and the input current is greater than 1.2 A, the conductor resistance must not
exceed 0.5 Ω.
If the device is not used in a cascade, a T-connector is not used, and no inductive OSSD loads (e.g.,
contactors) are applied, the conductor resistance must not exceed 2 Ω.
