Moeller Marine XI/OC SIGNAL MODULES 05/02 AWB2725-1452GB User Manual

05/02 AWB2725-1452GB

The XIOC modules are plugged onto module racks that provide the 
connection to the PLC. The modules are also interconnected 
through the module rack.

The integrated bus system ensures interference-free transmission 
between the individual slots on the bus. In addition, the bus 
system supplies the individual modules with the voltage that is 
required for internal signal processing. 

The supply voltage for the I/O electronics is applied directly to the 
corresponding I/O modules.

Four different module racks are available:

As a rule, the first module rack, which is used to take the CPU type 
XC-CPU100/200, is a basic module rack. You can add on several 
expansion module racks to the right side. The module racks must 
be arranged so that one CPU module and a maximum of 7 XIOC 
signal modules can be planned (a fig. 4).
