Product Details

Modicon 110-CPU-612-03 is a compact micro 110 plc cpu and reliable integrated i/o processor belonging to the Modicon Micro 110 series, manufactured by AEG Modicon. This compact controller combines CPU logic processing, built-in discrete and analog I/O, high-speed counter inputs and serial Modbus communication within one single DIN-rail housing. It executes LL984 ladder logic programmed via Modsoft software, suitable for standalone small automation machines and remote skid control. The onboard mixed I/O eliminates the need for extra I/O racks for simple control tasks, while supporting expansion to connect additional Modicon I/O modules for larger control demands. With integrated analog channels for sensor measurement and analog output for valve and drive setpoint, this micro 110 plc cpu supports closed-loop PID regulation, batch counting and sequential interlock. It carries hazardous location certification Class I Division 2, making it acceptable for mild explosive process zones. As a discontinued legacy spare, this integrated i/o processor serves as a drop-in replacement to restore full machine control for ageing Modicon Micro installations.

Supported Functions

This micro 110 plc cpu supports ladder logic program upload, download and online modification, cyclic scanning of onboard and expansion I/O, and battery backup for logic and register data. The integrated i/o processor provides high-speed pulse counting, interrupt triggering, PID closed-loop control, timer and counter operation, recipe storage and alarm management. This compact controller acts as Modbus master or slave to exchange data with HMI, SCADA and other Modicon controllers. It runs continuous built-in self-diagnostics for memory faults, communication errors, overvoltage and I/O short circuits, and triggers fault indication to protect the machine. It can expand its control scale by connecting compatible Modicon expansion I/O modules.

Core Functions

As an all-in-one compact controller, this micro 110 plc cpu executes user automation logic, reads digital and analog field sensors, and drives actuators through its native I/O. Its serial Modbus interface links the local machine to supervisory systems, while high-speed inputs handle fast encoder and trigger signals without CPU scan delay. This integrated i/o processor works as a direct spare to rebuild standalone machine control for ageing Modicon Micro automation systems.
