Using spare, standard I/O enhances functional safety while reducing costs and footprint

摘要

Cranes, industrial elevators and woodworking machines, as well as those countries not using international standards, can improve functional safety by capitalising on unused, standard I/O channels, according to a new report from ABB By using the spare, standard I/O channels within ABB's AC500 programmable logic controller (PLC), the functional safety of machine applications can be cost-effectively enhanced, says a new report from ABB. Using the PLC, together with ABB's AC500-S safety CPU, incurs no extra control system costs by avoiding additional safety I/O modules or an increase in cabinet dimensions.
