The contactor B6S-30-10-2.8 (24 V DC) is recommended as interface contactor due to its internal spark suppression.
Spark suppression is necessary for all types except the AF types to maintain a reasonable service life.

Connecting more than one expansion module
To connect several expansion modules to the UMC100.3 use the UMCIO-CAB cable to connect the first module with the UMC. And
use the IOIO-CAB cable to connect the first module with the second module and so on. The module order does not matter.
