Kuhnke FIO

Product Information

Kuhnke FIO is a system of I/O modules to link the process signals within an EtherCAT network. It consists of the bus coupler and various I/O modules.

In the EtherCAT bus coupler or small controller, the signal processing and the generation of system voltages occur for the I/O module. Between the I/O modules, the EtherCAT protocol is used.

At the end of the modular device the connection of go-and-return line will be closed automatically or transmitted with the help of an extender to the next EtherCAT participants. The small control Kuhnke FIO Controller 113 is a mini-IPC on ARM based.

Modern industry-standard interfaces allow the connection to higher-level controllers as well as the connection of fieldbus devices. The Kuhnke FIO Controller 113 can be individually extended with modules of the FIO I/O system, the programming is done with CODESYS V3.

In addition, you can simply integrate safety technology in the form of the Kuhnke Safety I/O module in order to meet the safety requirements of the Machinery Directive 2006/42/EC.

Everything you need to get into the world of control is combined in our Kuhnke starter kits. For example, the CODESYS starter kit Motion offers a modular PLC with a controller module and CODESYS programming for stepper and BLDC motors.

The new Kuhnke FIO CAM Control module is a separate electronic cam controller for cyclic recurring workflows. Whether self-sufficient or networked, it reduces processor load thanks to the highest dynamics and accuracy.
