Product Q&A
Q: What is the primary role of the UTNH23A in a V-Series system? A: It provides the physical and logical Ethernet interface required for the controller to participate in industrial network communications.
Q: Does this module require external power wiring? A: No, it is powered directly through the controller’s backplane bus once seated in the rack.
Q: Can multiple UTNH23A modules be used in a single rack? A: Yes, depending on the CPU’s capacity, multiple modules can be installed to separate control traffic from management traffic.
