System conception
Power module
In the system ricos FLEX the power supply is established by power modules. These are either inte-
grated to the bus coupler or may be installed between the extension modules. Depending on the
power module isolated areas of the DC 24 V power section supply may be defined respectively the
electronic power supply may be extended with 2 A.
For better recognition the color of the power modules are contrasting to the extension modules.
Extension module
Each extension module consists of a terminal and an electronic module.

Terminal module
The terminal module serves to carry the electronic module, contains the backplane bus with power
supply for the electronic, the DC 24 V power section supply and the staircaseshaped terminal for wir-
ing. Additionally the terminal module has a locking system for fixing at a mounting rail. By means of
this locking system your ricos FLEX system may be assembled outside of your switchgear cabinet to
be later mounted there as whole system.
Electronics module
The functionality of a ricos FLEX extension module is defined by the electronic module, which is
mounted to the terminal module by a sliding mechanism. With an error the defective electronic
module may be exchanged for a functional module with standing installation. At the front side there
are LEDs for status indication. For simple wiring each module shows corresponding connection in-
formation at the front and at the side.
