Network interface modules
Presentation
The range of NIM network interface modules comprises 9 standard NIM modules.
Each module is dedicated to a specic network or bus:
Network or bus Standard network interface module
Ethernet Modbus TCP/IP, dual port STBNIP2311
Ethernet Modbus TCP/IP STBNIP2212
EtherNet/IP STBNIC2212
CANopen STBNCO2212
Modbus Plus STBNMP2212
Fipio STBNFP2212
I
nterBus STBNIB2212
Probus DP STBNDP2212
DeviceNet STBNDN2212
All NIM network interface modules are supplied with two removable terminal power
supply connectors: one screw-type and one spring-type.
Power supply for network interface modules
The NIM network interface module is supplied by an external 24 V  power supply.
It converts this voltage to 5 V  to provide the 5 V  logic power to the I/O modules
of the island’s primary segment.
The 5 V logic power supply integrated in the NIM module provides a maximum
current of 1.2 A (operation in extended temperature ranges, see page 22).
This current can be increased by adding an STBCPS2111K auxiliary power supply
that also provides a maximum current of 1.2 A (operation in extended temperature
ranges, see page 34).
The STBCPS2111K auxiliary power supply module must be used with an
STBPDT10K power distribution module placed after it.
The 5 V logic power for the I/O modules in the expansion segments is provided by
the STBXBE1300K BOS bus expansion module placed at the beginning of these
segments. In the same way that an STBCPS2111K auxiliary power supply module
can be added for the primary segment, if the required current exceeds 1.2 A (see
page 34).
