1715-OB8DE A-B  Control Unit

Connecting to Allen-Bradley® PLC I/O is fast, convenient, and reliable with the Allen-Bradley Bul. 1492 wiring system. Unlike conventional terminal blocks, the Bul. 1492 wiring system connects to both digital and analog PLC I/O modules through pre-wired and pre-tested cables. The interface modules are mounted onto a standard DIN #3 Rail. Pre-printed adhesive label cards containing fieldwiring information are included for each interface module and I/O module combination.

Benefits • Reduced Wiring Time —PLC I/O module to field device wiring is completed in a fraction of the time when Bulletin 1492 wiring systems are used as compared with the traditional method of wiring. • Reduced Wiring Errors—wiring system cables are pre-tested to achieve 100% accurate connections and eliminate the need for point-to-point checking of wiring. • Faster Troubleshooting and Easier Maintenance—Diagnostic capabilities such as fuses, blown fuse indication, and fieldside ON-State LEDs allow maintenance personnel to quickly locate faults, reduce downtime, and improve overall productivity. • Increased Volume and Productivity —wiring system can be up to 30 times faster to install than traditional point-to-point wiring, enabling OEMs and panel builders to build panels faster and produce more machines.• Reduced Wire Preparation and Routing—Wiring systems eliminate the time and costs that are associated with stripping and cutting wires. Routing wires is much easier with one wire versus 20 - 40 with traditional wiring methods. • Labeling and Marking—Pre-printed, PLC I/O-specific adhesive label strips for quick marking of IFM module terminals save labor that is compared with point-to-point wiring that requires labor-intensive wire markers. • Simplified Design—Design engineers can simplify their panel drawings by calling out an IFM and pre-wired cable instead of having to detail every wire and terminal block aiding the installer and the End User. • Increased DIN Rail Density—DIN Rail space can be reduced by more than 50%. Narrow IFMs are also available for additional space savings. • Quality-Looking Panels—The pre-wired cables and IFM wiring system modules organize the wiring in your panel and provide a consistent look. • Fewer Parts, Less Inventory and Lower Carrying Cost—A wiring system involves an IFM and the cable, versus the block, barrier, jumper, markers, wires, and swing arms associated with traditional hardwired systems. • Design Flexibility—To develop a cost-effective system, the hardware components must meet the needs of the design engineer. Rockwell Automation provides the broadest range of digital and analog systems in the industry.
