SC129 – Digital I/O (RC2014)

SC129 is a digital I/O module designed for the RC2014 bus.

SC129 version 2
SC129 version 1

There are two versions of this design. Version 1 has the standard single row bus connector while version 2 has the enhanced bus connector. Another minor difference is the version 2 kit includes a box header for the I/O signals. Both versions work with the standard RC2014 bus and the enhanced RC2014 bus. The change to the enhanced bus connector now means all SCxxx products with the ‘standard’ module shape use the enhanced bus connector while all SCxxx products with the low profile module shape use the standard bus connector.
