Features

• A graphic HMI program that is easy-to-use and a reliable PLX system have been adopted.
• Through the use of an HMI program that is suitable for 21CFR PART 11, only approved users can change control variables.
• The highest-level of credibility and safety are guaranteed through the use of the PLC system.
• Pollution is prevented during a blackout. This product can work normally after a blackout by using a program to compensate for a blackout.
