FAQs
- Q: What is the difference between sourcing and sinking outputs?
A: Sourcing outputs switch the positive side of a DC load; sinking outputs switch the negative side. Select the variant to match the field wiring.
- Q: Does this base module include Ethernet?
A: Yes. The base module includes Ethernet for software communication, ladder upload/download, online monitoring, firmware upgrade and webserver connectivity.
