The I/O terminal expansion block lets you wire I/O directly to the Kinetix® 300 or Kinetix 350 drive without the use of an extension cable and a separate terminal block. The I/O terminal expansion block securely mounts to the drive with its own mounting screws, simplifying I/O wiring. The I/O terminal expansion block is attached to the IOD - I/O terminal on the front of the drive. Using the expansion block requires additional cabinet height and width.
