HITACHI MPD110A Graphic Operator Terminal

The HITACHI MPD110A is a versatile graphic operator terminal designed to bring visual intelligence to industrial control systems. It features a 4-inch monochrome LCD with 160×64 pixel resolution, capable of displaying text, simple graphics, bar graphs, and trend charts. The integrated resistive touch screen allows operators to interact directly with screen elements, navigate menus, and input data. This terminal serves as an economical solution for applications requiring more than just text-based displays, offering a clear window into machine operation.

Applications

The MPD110A is suitable for a wide range of machinery including injection molding machines, printing presses, textile equipment, and food processing lines. It provides operators with real-time production data, allows them to adjust parameters, and displays alarms clearly. The trend display function helps in analyzing process variations over time, facilitating predictive maintenance.

Configuration and Software

Development is performed using Hitachi's MPD-EDIT software, which offers a library of graphic elements, alarms, and communication drivers. Engineers can design screens with dynamic objects (buttons, numeric displays, bar graphs) and link them directly to PLC memory addresses. The software also includes simulation mode for offline testing. Projects are downloaded via serial cable.

Reliability and Environmental Compliance

Built for factory floor environments, the MPD110A is resistant to vibration (10–57 Hz, 0.075 mm amplitude) and electrical noise (IEC 61000-4-2/3/4). Its IP65 front panel protects against water spray and dust. The unit is CE marked and UL listed, ensuring compliance with international safety standards.

With its graphic capabilities and touch interface, the HITACHI MPD110A graphic operator terminal enhances operator efficiency and machine transparency in cost-sensitive applications.
