CPU124-2Q DC/DC/DC
• Excellent value for money;
• 14-point digital input, 10-point digital output, 4 modules can be expanded;
• 24V power supply, transistor 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.
