Allen-Bradley 1747-L551 engineering application examples
US Bottled Water Production Lines: Coca-Cola's Atlanta plant uses the Allen-Bradley 1747-L551 as the master controller for 12 bottling lines, connected via 1747-SN modules to distributed I/O stations for filling valve accuracy control. The system achieves a peak production capacity of 48,000 bottles per hour and a mean time between failures exceeding 28,000 hours.
Australian Mine Ventilation System: Rio Tinto Group's Western Australian iron ore mines deploy 32 Allen-Brawley 1747-L551 processors, coupled with 1746-FIO4I analog modules for real-time damper opening control. The wide operating temperature range (-10°C to 55°C) allows for successful operation in the mine's hot and humid environment, reducing the failure rate by 41% compared to Japanese PLCs.
