• Excellent value for money;
• 14-point digital input, 10-point digital output, 4 modules can be expanded;
• The machine integrates 2 communication ports, supports PPI communication and free port communication, and relay output;
• Using FLASH technology to keep power off for a long time, without battery support, data can be stored for up to 10 years;
• Unique AES iterative encryption algorithm to protect users' intellectual property rights;
• With two communication interfaces, both support PPI communication protocol.
