5.2.2 Bus Coupler DI16/DO16
The Kuhnke FIO bus coupler DI16/DO16 is an EtherCAT IO module providing the
functions of the Kuhnke FIO bus coupler and Kuhnke FIO DI16/DO16 modules in a
single unit. Its E-bus power has been reduced to 2 A to make it particularly fit for
use in smaller blocks of modules. The module's bus coupler element converts the
physical transfer technology (twisted pair) to LVDS (E-bus) and generates the
voltages required by the LVDS modules. The module features 16 digital inputs and
16 digital outputs. The E-bus port on the side allows a flexible extension of the bus
coupler DI16/DO16 by Kuhnke FIO-series EtherCAT I/O modules.
Information
Best noise emission results are obtained by connecting the shield of the EtherCAT cable to
operative earth.

NOTE
For the bus coupler with digital inputs and outputs, both 24V connections must be used for
complete functionality.
The logic (coupler) is supplied with voltage on the left and the IOs (load) on the right.
