How to find the right terminal module for a electronic module for your
application:
No
Do you need
a terminal module with access
via terminals to the AUX1 bus (for example, for
protective conductors or the use of additional potential up to
the maximum rated load voltage
of the module)
?
Do you need
terminals 4 and 8 :
-- functionality of a module (e.g. counter module)
-- connection of non-required signal lines with the same
potential as P1/P2 (e.g. connection of
non-equivalent sensors)
?
Yes
No
Yes

Not for electronic modules with technological functions
No
Yes
Do you need
a terminal module that is
suitable for all electronic modules
(width 15 mm) and that provides access to
the AUX1 bus via terminals
?
