EtherCAT® I/O

The BRUNNER EtherCAT® I/O is part of our EtherCAT® product portfolio. It is a multi-purpose I/O module that provides a wide range of interfacing features in a very compact and easy to mount case.

BRUNNER EtherCAT® I/O enables fast and easy connection and integration of digital and analogue I/O signals from switches, sensors, actuators etc. to an EtherCAT® network at a competitive price point. Beside standard I/O functionality, the device also provides serial ports and a CAN interface. The Encoder Interface with various counting modes and the PWM outputs for driving an external power stage are further powerful features.

These interfaces comply with the EtherCAT® Modular Device Profile Standard. Further, CoE (CAN application protocol over EtherCAT®) and Distributed Clocks are supported.

EtherCAT® I/O is designed to simplify the cabling efforts by providing easy push-in connectors for I/O and power. Transmitting digitalized I/O data over EtherCAT® networks reduces complexity and costs for the installation of control and signal wiring. Its robust industrial design and snap-on mounting capability on various top hat DIN rails allow the fast and easy mounting and connection of the device directly at the signal source.
