PSB 9000 3U Slave Series
There are several possible combinations of standard models and Slave models:
Combination 1:
Multiple PSB 9000 3U (with display)
All models of the standard series can be combined to
themselves in master-slave (up to 10 units on one bus)
Advantage of this combination: every unit could be master
or slave; the slave show their own actual values and the
entire system can also be controlled manually.
Disadvantage of this combination: higher costs compared
to a system with PSB 9000 3U Slave models
Combination 2:
One PSB 9000 3U with one or multiple PSB 9000 3U
Slave
This is the intended combination for models of PSB 9000
3U Slave series, as it can be found in series PSB 9000
15U and PSB 9000 24U, for example.
Advantage of this combination: lower costs
Disadvantages of this combination: in case the master
fails, the entire system cannot work. After reconfiguring
any Slave unit to be master, which can be done via soft-
ware and remote control, the system can continue to oper-
ate. Other: only 15 kW models of both series can be used.
Combination 3:
Multiple PSB 9000 3U with one or multiple PSB 9000
3U Slave
An already existing MS system with only PSB 9000 3U
is going to be extended by one or multiple PSB 9000 3U
Slave units.
Advantage of this combination: in case of a failing master,
any other PSB 9000 3U unit can be quickly reconfigured
to be master.
Disadvantages of this combination: higher costs, because
even some of the slave units may have a display and
control panel which they actually don’t need. Other: only
15 kW models of both series can be used.
