What We Deliver
Intelligent Control
Built-in PID, vector control (open / closed loop), and pre-configured macros for pumps, fans, conveyors, and elevators.
Communication
Standard Modbus-RTU; optional Profibus / CANopen expansion for system-level integration.
HMI & Monitoring
HR30/60/80 series for parameter cloning, multilingual UI, and remote monitoring extensions.
OEM/ODM
Hardware customization, firmware algorithm tuning, GUI/HMI branding, and project-specific engineering.
Compliance
CE & ISO9001 certified; support for EAC/GOST, SASO, and other international documentation.
