It integrates traditional sequence control with advanced analog loop control, allowing the block processing of PID algorithms directly within the CPU unit. This module eliminates the need for separate analog regulatory controllers by executing seamless sequence and process loop execution simultaneously. Outfitted with an onboard peripheral port, standard RS-232C connectivity, and internal flash memory storage, it provides a stable and optimized architecture for complex industrial process
