The 621-9962 I/O Extender Board can be used to adjust or troubleshoot a specific I/O module in an I/O rack. By removing the I/O module from the rack, inserting the 621-9962 into the rack, and inserting the I/O module into the I/O Extender Board, you can extend the I/O module from the I/O rack backplane. The connectors on the front of the I/O Extender Board duplicate the function of the I/O rack backplane connectors.

NOTE
– The I/O Extender Board maybe installed in any I/O rack (621-999OC, 621-9991C, or 621-9992C).
– The I/O Extender Board may be used to adjust or troubleshoot 622 Motion ControlModules installed in an augmented I/O rack.
