Periphery modules
8x periphery modules
When using System SLIO modules, you must always mount the power
module 007-1AB00 - DC 24V 10A, because the CPU does not provide a
power section supply due to the system.
The color-coded power modules are used when the CPU does not provide power section
supply
, like the CPU iC921xM-x. These are also to be used if the power section supply of
the I/O level or the electronic power supply is no longer sufficient. Depending on the
power module used, you have the option of forming isolated groups. The power modules
are to be supplied externally with DC 24V. Each power module has over voltage and
reverse polarity protection.
The periphery modules are available in the following versions, whereby of each the elec-
tronic part can be replaced with standing wiring:
■ 8x periphery modules for a maximum of 8 channels.
– Standard periphery modules
– Safety periphery modules
■ 16x periphery module for a maximum of 16 channels.
Each 8x periphery module consists of a terminal and an electronic module.
1 Terminal module
2 Electronic module
According to structure and dimensions the safety periphery modules correspond to the
standard periphery modules of the System SLIO. For better recognition the color of the
safety modules is yellow
. Please consider that the safety electronic module may only be
used at an yellow terminal module! The operation with mechanical compatible terminal
modules is not allowed.
