Appendix C
Selection Table for 1771-to-1756 Analog I/O Swing-Arm Converter Module and Pre-Wired Cable
How To Use Matrix A) In the left most column, find the catalog number of the 1771 analog I/O module.
B) Follow that row to the right most column to find the compatible 1756 I/O module.
Review the matrix carefully and review the I/O module Installation Manuals with attention to the
specifications to determine full compatibility.
C) Find the column in the row you selected that contains a capital letter (e.g. A). The catalog number of the
1492 1771-to-1756 Converter is listed at the top of that column. The capital letter from the row and
column intersection indicates the last character of the catalog number for the 1492 cable that connects from
the converter module to the 1756 I/O module (right most column). The FULL cable catalog number is
1492-CONACAB
x, where x is the above letter.
Footnotes:
Three digit number to indicates cable length in meters and tenths of meters (005=0.5 meters).
Available lengths = 1.0 (010) and 0.5 (005) meters.
To understand any issues concerning I/O module compatibility refer to the conversion module wiring
diagrams and the specific I/O module's Installation Manual especially the specification and wiring
instruction sections.
