4.2.1 Terminology and Ordering Information Cables: Except for the style of “Slide-on Cover” supplied the pre-wired cable assembly used for A-B I/O modules and Honeywell I/O modules are identical. All Honeywell cables must have the HW designator in the catalog number. Basic pre-wired Cable Assembly catalog numbers:  1492-CABLE-Cable Assembly for Digital (discrete) IOM’s (A-B Slide-on Cover supplied)  1492-ACABLE-Cable Assembly for Analog IOM’s (A-B Slide-on Cover supplied)  1492-HWCAB-Cable Assembly for Digital (discrete) IOM’s (Honeywell style Slide-on Cover)  1492-HWACAB-Cable Assembly for Analog IOM’s (Honeywell style Slide-on Cover) Example catalog number:-1492-HWACAB ### UB 1492-HWACAB Indicates an analog IOM cable supplied with a Honeywell style cover. The ### indicates the desired cable length in meters. Two standard lengths are provided (use 010 for one meter or 3.28 feet) and (025 for 2.5 meters or 8.2 feet). Custom cable lengths up to 99 meters (374.72 feet) can be specified. UB indicates the wiring layout (In this case a cable pre-wired for module TC-IAH161 and single ended current inputs). Different letter designators are used with other IOM’s. RTPs: Honeywell always refers to the Din rail mountable terminal assembly as an RTP (Remote Terminal Panel). Rockwell uses the acronyms IFM, RIFM, AFIM, RAIFM, or XIM. The Rockwell catalog numbers begin with 1492- followed by alpha-numeric characters that indicate desired features, options, and associated IOM. When ordering RTPs, the following RTP catalog numbers are used:  1492-IFM - Identifies an RTP for use with Digital (discrete) I/O  1492-RIFM - Same as IFM with removable terminal blocks  1492-AIFM - Identifies an RTP for use with Analog I/O  1492-RAIFM - Same as AIFM with removable terminal blocks  1492-XIM -Identifies a “Relay Expander Module” that provide relays on the RTP for use with Digital Output IOM’s Example catalog number: - 1492-AIFM6TC-3 This RTP is use with the 6 channel TC-IXL062 T/C input module.
