4.2 Bus coupler DI16/DO16
The Kuhnke FIO bus coupler DI16/DO16 is an EtherCAT IO module that
combines the functionalities of the existing single modules Kuhnke FIO bus
coupler and Kuhnke FIO DI16/DO16 into one device. It is designed with a
reduced E-bus supply of 2A specifically for use in smaller module blocks. In
the bus coupler part the module converts the transmission physics from
Twisted Pair to LVDS (E-Bus) and the generation of the voltage for the
LVDS modules takes place. In addition, the module has 16 digital inputs and
16 digital outputs. About the lateral E-bus connection, the bus coupler
DI16/DO16 can also be flexibly extended with EtherCAT I/O modules of the
series Kuhnke FIO.
You will get the best results concerning disturbing emission, if you put the
shielding of the EtherCAT cable on the function earth.
Use for it e.g. Shield connection terminal block (see section 5.2)
