Connection options

Connection left:
1 x M16 x 1.5 cable gland with multipole connection (M12
plug according to IEC 61076-2-101, 4-pole) to an 8 cm or
80 cm long cable
Connection right:
1 x M16 x 1.5 cable gland for external initiator
9.2 Number of connectable control
heads
In AS interface versions with extended addressing range (A/B slave),
1 master can communicate with 62 slaves.
In AS interface versions with addressing range 31 slaves, a maximum
of 31 control heads can be connected to a bus line (the address
range restriction).
9.3

Bus line length

The bus cable may be a maximum of 100 m long. When designing the
system, consider the length of the round cable leading directly to the
control head (see example calculation in the Operating Instructions).
