specifications
Cable
Flat cable (yellow) 1,5mm²
Round cable (black) 1,5mm² ou 2,5mm²
Wires
brown - Field bus system cable (ASI+)
blue - Field bus system cable (ASI-)
We recommend the use of round cables for wirings in switch cabinets.
3.2.2 Power supply
An additional power supply source may become necessary as soon as the energy delivered by the slave
from de bus is not sufficient for the current consumption of the AS-Interface slave and the corresponding
peripheral components such as sensors and/or actuators.
Typical applications requiring an additional power supply :
- Photoelectric safety locking,
- Inductive loads (switching devices, valves, etc..).
The additional power supply unit must be fitted with a protection cutoff device and
must be in conformity with PELV directives according to IEC 364-4-41.
Wiring in switch cabinets is effected with single wires. It is also possible to use an adapted round cable or
the specific profiled flat cable.
Flat cable
black - Auxiliary supply 24V DC
red - Auxiliary supply 230V AC
Wires
brown - Auxiliary supply AC or 24V DC (+24V DC)
blue - Auxiliary supply AC or 24V DC (0V)
