II. ASI version with extended address range (A/B Slave)
1 Master can communicate with 62 Slaves with the ASI version with extended address range (A/B Slave).
As in the standard case, the bus cable with extended address range according to ASI specifications my be
a maximum 100 m long.
ATTENTION!
If an A/B Slave device is being used as a replacement for a standard device, a
configuration error arises due to the different ID codes!

Characteristics of the A/B Slave variant compared with the standard case
• 62 Slaves per Master
• The yellow OUT 4 LED on the ASI circuit board is no longer controllable, since the fourth output bit
used up to now is now used for the addressing.
• Limitations in power supply due to the nominal current of the inductors:
Only 2 solenoid valves can be connected at the same time; the third solenoid valve can only be
hooked up after 100 ms have passed.
NOTE Maximum cable lengths also vary when other cable cross sections are used (see ASI
specifications).
