The maximum number of devices that can be connected to
the BUS depends on their total absorption and on the distance
between the connection point and the power supply. The power
supply unit can deliver up to 1,2 A hence, the maximum number
of devices will be determined by the sum of the absorptions of
the single devices you need to install (see absorption table in
the following pages). For the purposes of the above-mentioned
calculations included in the “Technical features”.
When calculating the absorptions, it is also necessary to consider
the availability of current according to the length of the cable.
When setting up, please observe the following rules:
NOTE:
The maximum current available at the end of the 250 m SCS BUS cable 492 31 is 600 mA.
3) For optimum division of the currents on the BUS line power supply should be
positioned in the middle.
1) The connection between the power supply and the furthest away device must not be
longer than 250 m
2) The overall length of connections should not exceed 500 m (extended cable)
