Open and Modular System
With a standard NIM network interface module it is possible to realize an island
with only one segment (a “single” segment) comprising up to 32 input/output
modules (excluding PDM power distribution modules, network interface module,
bus termination and auxiliary power supplies).
Single segment standard Advantys STB
In the example above, the primary segment comprises:
1 STB Npp 2212: a standard type 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 210p: 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 310p: 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, STB ACp, STB DDp: digital or analog I/O modules requiring DC power.
They are installed after the PDM STB PDT 310p module.
6 STB XMP 1100: bus termination (1).
Auxiliary internal power supply: The auxiliary power supply module STB CPS 2111
supplies a c 5 V logic voltage (1.2 A) from an external c 24 V power supply.
