FAQs

What makes this a good "entry-level" CPU?

It provides all basic PLC functions at a lower cost point, with enough I/O for simple applications and the ability to expand if needed.

Can I control 240V AC devices with the relay outputs?

Yes, the relay outputs can switch up to 240V AC at 2A, making them suitable for controlling contactors, motor starters, or lighting.

How many additional I/O modules can I add?

You can add up to 2 additional signal modules, which can significantly increase your total I/O count for more complex applications.

Does it support communication with other devices?

Yes, through its PROFINET port it can communicate with HMIs, other PLCs, and support protocols like Modbus TCP for device connectivity.

What's the advantage of AC power input?

It eliminates the need for a separate 24V DC power supply in your control panel, simplifying your electrical design and reducing component costs.
