Open and Modular System
With a basic network interface module it is possible to realize an island with only one
segment (a “single” segment) comprising up to 12 input/output modules (excluding
PDM power distribution modules, network interface module and bus termination).
Single segment basic Advantys STB
In the example above, the single segment comprises:
1 STB Npp 1010: an NIM (Network Interface Module). It is placed at the beginning
of the primary segment. Each island must have one NIM module only.
2 STB PDT 2105: a PDM (Power Distribution Module). It is installed immediately to
the right of the NIM and supplies a 115/230 V to the input/output modules
requiring AC power.
3 STB DAp: digital I/O modules with AC power.
4 STB PDT 3105: PDM power distribution module. It is installed after all the
a 115/230 V I/O modules. It provides c 24 V to the I/O modules requiring DC
power.
5 STB AVp and STB ACp: analog I/O modules requiring DC power. They are
installed after the PDM.
6 STB XMP 1100: bus termination, supplied with the NIM network interface module.
Internal power supply: The NIM network interface module STB Npp supplies a
c 5 V logic voltage (1.2 A) from an external c 24 V power supply.
