Bulletin 1492

Bulletin 1492 is Allen-Bradley's Programmable Controller Wiring Systems family — a broad catalog of interface modules, terminal blocks, and wiring accessories engineered to simplify field-side connections between PLCs and I/O devices. The family spans Interface Modules (IFM), Removable Interface Modules (RIFM), Analog IFMs (AIFM), and Interface eXpanders (XIM), along with an extensive range of wire markers, cable ties, and tooling. Catalog numbers follow a structured format: the module class position (IFM, RIFM, AIFM, XIM) identifies the interface type; the pin-count position (20 or 40) reflects 8–16 or 16–32 I/O point capacity; the function/voltage code (F, FN, D24, D120, D240) defines feed-through rating or LED indication voltage; and option suffixes (-F, -FS, -DS) specify fusing, blown-fuse indication, or isolated wiring configurations. Among the 3,000-plus SKUs currently stocked, popular items include wrap-around wire markers in multiple label sizes (12×18 mm through 51×150 mm), printable wire marker cards for standard and large-gauge wire, and the 1492-KWC cutting tool. For full selection guidance, consult the Bulletin 1492 Technical Data (1492-TD008).
