About the Control Interface Breakout Board

These boards provide discrete wiring terminations for signals on the CN1 I/O connector. The
44-pin breakout board (catalog number 2090-U3BB2-DM44) can be used with any Ultra3000
drive. The 12-pin breakout board (catalog number 2090-U3BB-DM12) is intended for use with
SERCOS drives but may be used in non-SERCOS applications with minimal I/O requirements.

IMPORTANT

You must supply an external 5.2V DC auxiliary power source to retain control
power when main power is removed from Ultra3000 2098-DSD-005,
2098-DSD-010, and 2098-DSD-020 drives.
