EtherCAT® slave controller

EtherCAT®

  • 1,408 points for maximum input and output
    (analog input and output 176 ch)

    Users can create any configurations because of the coupler type. It can be also applied to the large-scale control system.

  • Passing down the I/O module assets of
    the EH-150 / EHV / EHV+ Series

    Power supplies, bases, and I/O modules (some are excluded) of the EH-150 / EHV / EHV+ Series can be used.

  • High-speed response and high reliability

    At the fastest pace, the communication cycle is 200 µs. When communication abnormalities occur, the output data can be retained.
