J2 Terminal Strip/Breakout Board

A 25-pin terminal strip kit is available for extending the encoder
signals from the J2 connector. The kit includes a 3-foot (1 meter)
interface cable a 25-pin terminal strip, and mounting hardware. Refer
to Appendix A, “Options and Accessories”.

a. ULTRA Master software automatically determines the presence or absence of a motor thermal

switch signal based on the motor selected in the Drive Select window. Allen-Bradley F-, H-, N- and
S-Series motors typically have thermal switches and signal continuity is provided on these motors.
LD- and Y-Series motors do not have thermal switches and signal continuity is not required.
