Electrical connection options for AS interface

The following connection concepts are available for the electrical connection of the control head:
• Cable gland with multi-pole connection on a cable (8 cm length)
• Cable gland with multi-pole connection on a cable (80 cm length)
with multi-pole connection (M12 plug
according to IEC 61076-2-101, 4-pole)
to 8 cm cable

11.3. Number of connectable control heads and
maximum length of the bus line
The bus cable may be a maximum of 100 m long. All AS interface lines of an AS interface string must be considered
for the design, i.e. even the drop lines to the individual slaves.
The level of expansion that is actually possible depends on the total number of all individual operating currents for
each control head, which are supplied via the bus at the common AS interface bus segment (see example calculation).
Standard: AS interface / 62 slaves (AS interface version with extended addressing range (A/B slave))
In AS interface versions with extended addressing range (A/B slave), 1 master can communicate with 62 slaves.
Option: AS interface / 31 slaves (AS interface version with 31 slave addressing range)
In this case, a maximum of 31 control heads can be connected to a bus line (address range restriction).

IEC 61076-2-101, 4-pole) to 80 cm cable
