Description
Application Scenarios
A manufacturer of small packaging machines faced high costs and long lead times using complex, modular PLCs for simple tasks like conveyor control and glue application. Each machine required a separate CPU, digital input module, and relay output module, increasing cabinet size and wiring complexity. By switching to the ABB PM554-RP, the manufacturer leveraged its 8 integrated digital inputs for sensors and 6 integrated relay outputs for actuators like solenoid valves and motors. This “all-in-one” design eliminated two additional modules per machine, cut cabinet space by 30%, and reduced total installed cost by 25%. The integrated RS485 port allowed for easy connection of a small HMI for operator interface, streamlining the entire control package.
