Table 6.4: CAN BUS cable cross-section
If a participant cannot be directly connected to the CAN bus, a stub line (branch line) must be
used. Since there must always be precisely two terminating resistors on a CAN bus, a stub line
cannot be terminated. This creates reflections, which impair the rest of the bus system. To
minimize these reflections, these stub lines must not exceed a maximum individual length of
2 m at data transmission rates of up to 125 kbit/s, or a maximum length of 0.3 m at higher bit
rates. The overall length of all branch lines must not exceed 30 m.
The following applies:

Control input

There are two control input ports (input 1–5 or 6–10) on the rear of the device.
The CONTROL IN port is split into two halves:
•
•
The delivery includes 10-pole connectors. Conductor cross-sections of 0.14 mm² (AWG26) to
1.5 mm² (AWG16) can be used. Recommended connecting cable: Flexible CU strand, LiY, 0.25
mm². The control port is configured in IRIS-Net.
Caution!
! The maximum permissible voltage on a control input is 32 V.

In terms of rack wiring, standard RJ-45 patch cables with 100-ohm impedance (AWG 24/
AWG 26) can be used for short distances (up to 10 m).
The guidelines specified above for the network cabling must be used when wiring the
racks with each other and for the building installation.
The upper half has five freely configurable supervised, not isolated control inputs.
The lower half has five freely configurable isolated control inputs.
