Connecting Smart Connect Electronic Modules to the
TB 16IM-SC/TB 16SC Terminal Block
The following connection rules apply to the SC electronic modules:
You can connect up to 10 counter modules in an ET 200L-SC IM-SC
(with TB 16SC).
The slot immediately to the right of an AC module/relay module must
either have an AC module/relay module or be free (see the following ex-
ample).
Under certain circumstances the number of plug-in SC electronic modules
is limited (see the next page).
Note
If you use the TB 16IM-SC and TB 16SC together, you have a maximum of
16 slots available. This gives you up to 32 digital/analog channels, which
can include a maximum of 12 analog channels.
8 slots (A...H) are available to you on each terminal block.

The circuit schematic is shown on the front of every electronic module. Up to
two LEDs are located below the circuit schematic. In the operating mode, the
circuit schematic is covered by the labeling strip. The LEDs are visible
through the transparent part of the labeling strip.
