10.2.2.1 Configuration of the digital inputs 230 V AC and 24 V AC/DC
Base module and SIOX extension modules
The digital inputs of the base module and those of the SIOX extension modules can be configured to 230 V AC
(factory setting) or to 24 V AC/DC using jumpers.
Wiring of the digital inputs using the example of a SIOX extension module with switches
Warning about dangerous electrical voltage! Danger to life - Danger of electric shock!
BEFORE connecting and disconnecting, it must be ensured that no voltage is present at all
connections of the controller.
Configuration of the jumpers: Always carry out the work in a de-energised state and with the
connectors at the digital inputs disconnected!

Mixed operation of the voltage levels! If digital inputs with low voltage (230 V AC) and safety extra-
low voltage (24 V AC/DC) are required on a SIOX module, they must be separated by a digital input
connected to PE
!Practical tip: Use of 2 separate SIOX modules to handle only one voltage level per module.
