Multiple wiring (multi-drop) of connector
Multiple wiring of the UTAdvanced connector with other devices is possible within
the following multi-wire connection capacity range.
Multi-wire connection capacity (Two wires with the same cross-sectional area)
• Single wire 0.2 to 1.0 mm
2
/twisted wire 0.2 to 1.5 mm
2
• Twisted wire with bar terminal (without plastic sleeve) 0.25 to 1.0 mm
2
• Twisted wire with twin bar terminals (with plastic sleeve) 0.5 to 1.5 mm

If the UM is located at the end of a
segment for the CC-Link
communication wiring,terminating
resistors are separately needed.
These are to be prepared by users.
