Two-wire connection
The following configuration example shows a two-wire connection with the electronic
modules 8DI DC24V. You require further terminals so that sufficient terminals are available
for the 24 VDC sensor power supply when the TM-E15S26-A1 terminal modules are used. In
the example this is implement by the add-on terminal TE-U120S4x10. Per add-on terminal,
terminal modules of the same height must exist across a minimum width of 120 mm. You
can naturally also use other terminals for this configuration (for example, ET 200S potential
distribution module 4POTDIS).
