Requirements for the host interface
The host interface of the CLV can be operated as an RS 422/485 or an RS 232 interface.
shows the recommended maximum cable lengths as a function of the selected
data transfer rate.

To prevent interference, do not lay the cables parallel with power supply and motor
cables over long distances, e. g. in cable ducts.
5.4.2
Supply voltage
The CLV requires a power supply of 18 to 30 V DC for operation without a heater and
24 V DC +20 %/–10 % for operation with a heater (each functional extra-low voltage in
accordance with IEC 364-4-41). The functional extra-low voltage can be generated by using
a safety isloating transformer pursuant to IEC 742.
The power consumption of the individual types is as follows:
Power-up delay
The selected device number (default: 1) affects the power-up delay of the device. This is
useful if a large number of CLVs (e. g. in the SICK network) are to be supplied from one
power source.
