Ethernet coupler LF series

EtherCATProfiNetbus

Overview
The LF series distributed I/O system consists of the LF series communication coupler and XF series modules. A high-speed backplane bus between the coupler and modules enables microsecond-level response, making the system suitable for high-speed, high-precision control and data-acquisition applications. The modular range supports combined configurations to meet diverse customer needs.

Product Features

• High real-time performance with a compact form factor.
• High-speed backplane bus between coupler and modules for microsecond-level response.
• Support for diverse module combinations to address varied application requirements.
