The EtherCAT Flexslice System is designed to let you do more! It offers fast flexible expansion for motion applications and can be used with Trio or 3rd Party Masters.

Trio’s Flexslice input/output modules provide a robust, high speed and flexible solution for both motion control and general automation. EtherCAT cycle times down to 250μsecs are supported and the bus coupler uses EBUS technology to bring all the sub-modules on to the EtherCAT network with no degradation in performance.

The Flexslice system makes available a selection of digital and analogue I/O terminals as well as motion modules with pulse + direction outputs designed for precise positioning of stepper and servo motors via suitable drive technology.

The digital I/O modules have high-speed functionality. In addition, analogue modules and axis modules may be fitted to make a superbly tailored system that can be placed remotely from the master if needed.

All Flexslice modules support automatic addressing with the master to automatically detect and configure the modules on startup. The bus coupler supports up to 16 input/output modules which have a positive mechanical lock and bus connector, making a reliable EBUS connection through the backplane. The complete assembly can be DIN rail mounted.


To help with identification of each Flexslice modules' function, a handy removable tab is provided that can be written on. It simply slides in and out of a slot at the top of each module.


The robust metal chassis provides a good earth from the pcb of each module to the DIN rail to reduce noise and dissipate heat.


The easy to use push-in terminals makes wiring of the Flexslice system quick.



The field programmable FPGA allows customisation of the functionality of some Flexslice Modules using Motion Perfect v4. The program can be "locked-down" creating a unique function for a machine builder which protects the functionality from being copied.



The positive "click-to-lock" mechanism firmly clamps Flexslice modules to each other to form a Flexslice station. Simply push each module together and slide the quick release locks into position.
