✶
For applications with offside leakage current of >0.5 ma. Use 1492-IFM20D120N instead of 1492-IFM20D120A-2 or 1492-IFM20D120-2.
1. Locate I/O module required. The top row in each table indicates the I/O module for the I/O platform.
2. Locate the Interface Module Cat. No. column in the appropriate table.
3. Determine whether the interface module can be used with the I/O module, indicated by a letter code in the
appropriate Cat. No. colum
4. Build the Pre-Wired Cable catalog number: 1492-CABL_ _ _Letter Code.
⎯
The Letter Code in the table cell represents the suffix of the pre-wired cable catalog number.
For example: 1492-CABLE_ _ _A.
⎯
Specify cable length. Standard Lengths are 0.5 m, 1.0 m, 2.5 m, and 5.0 m. Replace the _ _ _ with 005, 010, 025,
or 050, respectively, to indicate the length. For example: 1492-CABLE010A = a 1.0 m cable with Letter Code A.
