Technical Specifications Display Size: 12‑inch color touch‑screen display Operation Mode: Resistive touch panel input On‑board Memory: Local memory for HMI project screen files Communication Interfaces: Multiple serial and Ethernet communication ports Operating System: Embedded industrial real‑time operating system Power Supply: 24 VDC nominal input power Operating Temperature: 0 ℃ to +55 ℃ Storage Temperature: ‑20 ℃ to +70 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Panel‑mount HMI form factor for cabinet cut‑out installation Certifications: CE, UL industrial HMI compliance
Functional Features 12‑inch color touch screen provides visual industrial monitoring and operation interface. Supports HMI project screen display, real‑time variable data display and alarm event recording. Multiple communication ports realize data connection with various series GE PLC and third‑party controllers. Resistive touch panel supports on‑site parameter modification and equipment operation command input. Local storage for alarm log and historical event data. 
Application Scenarios On‑site human‑machine operation terminal for chemical, manufacturing automation control cabinet. Local monitoring and operation station for water‑treatment and municipal industrial equipment. HMI operator interface matching GE PACSystems and Series 90 PLC control system.
Structural Characteristics Cabinet panel‑mount housing structure with installation sealing gasket. Front‑side 12‑inch color display and resistive touch input surface. Front‑panel power status LED indicator. Rear‑side terminal block for 24VDC power input and communication interface sockets.
Working Principle After power‑on, HMI loads pre‑downloaded screen project file. It establishes communication link with connected PLC controller via rear‑side communication ports, continuously reads real‑time process variable data and refreshes screen display.
Installation Requirements Install HMI unit into reserved cut‑out opening on control cabinet front panel, fasten with mounting clips. Guarantee sealing gasket is well placed to keep front‑face protection performance. Connect 24 VDC power supply to rear‑side power terminal, confirm input voltage matches rated requirement.
