Omron's C120-CPU is a programmable logic controller (PLC) engineered for reliability and efficiency in automation processes. This model utilizes advanced control elements, including LSI, TTL, and C-MOS technology, enabling it to perform effectively under various conditions. The programming for this PLC is conducted through a ladder diagram system, which simplifies the coding process and enhances user understanding.

Execution of tasks is swift, with an execution time per address of between 5 to 10 microseconds for basic instructions, ensuring responses happen quickly. The C120-CPU can manage approximately 2.2K addresses, integrating both RAM and EPROM with an overall memory size of 8K bytes, making it capable of executing a robust set of functions.

Timers and counters are integrated in a notable capacity, featuring 128 timer points and corresponding 128 counter points, with the capacity of timers reaching up to 999.95 and counters hitting a total of 9999 counts. The system is equipped with 8 temporary memory relays and 45 special auxiliary relays, allowing for advanced control and logic operations.

Data handling is facilitated through 512 points of data memory relays, each providing 16 bits of information. The controller accepts a control input signal for RUN/STOP control, represented by the START INPUT. Output signals indicate the RUN mode via a RUN OUTPUT signal.

Powering this unit requires a supply of 24V DC at 0.14A, which is conveniently incorporated into the design, streamlining installation requirements. In summary, the Omron C120-CPU is a highly capable PLC that can address complex automation challenges through its extensive features and efficient design.
