Labeling for the 1492 Interface Module
Several different stick-on label sets are provided on a single card with 1492
Interface Modules. Each label set is identified with an I/O module catalog number
and words “upper” and “lower” to identify which terminal strip the label should be
affixed to.
The table on the following page identifies 32-point labels (SLC = decimal
addressing, PLC = octal addressing) and their location on the interface module. Peel
off the appropriate label for your 32-point module and apply it to the interface
module. The following is an example for the 1746-IV32 module.
