IO-Link HubUR-DS Series
IO-Link device that connects multiple standard sensors
and actuators to an IO-Link Master. (IO-Link Hub)
- IO-Link Hub connecting to an IO-Link Master, supporting Digital I/O, Analog I/O, and Temperature inputs
- IO-Link Hubs that can support Digital Inputs or Outputs up to 256 points (16 channels x 16 points)
*When connected to the OPTEX FA UR Series. - By connecting to an IO-Link Master, various I/O functions can be expanded.
This distributed configuration contributes to space-saving, reduced wiring, and improved noise resistance. - A new IO-Link Hub supporting RTD input is now available.
It allows temperature measurement using pt100 RTD sensors, with data transmitted and monitored via IO-Link communication.
