Cable lengths as a function of operating voltage and load current
The maximum cable length is determined by voltage drops on the supply and signal lines.
The following conditions apply for the necessary operating voltage U
B
at the input terminals of the connec-
tion unit:
• U
B
must be greater than the permissible nominal voltage limit of 16.8V.
NOTICE
The recommended operating voltage is 19V!
Leuzeelectronic recommends an operating voltage U
B
of 19V at the input terminals of the con-
nection unit.
Ä The operating voltage should not be allowed to drop below the recommended value if possi-
ble.
• The necessary operating voltage U
B
must also ensure the function of the downstream devices.
• Once the operating voltage U
B
has been determined, check whether the resulting signal voltages
are sufficient for the downstream devices.
• Take into account the voltage drops in the safety sensor – up to 3.2V – and on the signal wiring.
