HITACHI MPD060A Operator Interface Display

The HITACHI MPD060A is a cost-effective operator interface designed to provide local human-machine interaction for small to medium-sized automated systems. It features a 2-line by 20-character liquid crystal display (LCD) with adjustable backlighting, allowing operators to view machine status, production counts, fault messages, and parameter values clearly. Six programmable function keys enable direct operator input for mode selection, setpoint adjustment, and alarm acknowledgment without requiring a full HMI panel.

Key Features

• Clear Text Display: 2-line × 20-character LCD with backlight (green or amber, software selectable) for optimal visibility in various lighting conditions.

Applications

The MPD060A is ideal for simple machine control where a full graphic HMI is unnecessary. Common applications include small packaging machines, conveyor systems, HVAC units, and pump stations. It provides a cost-effective way to give operators local control and visibility, reducing the need for central SCADA systems. It can also serve as a diagnostic tool for drive parameters when connected to Hitachi inverters.

Configuration and Programming

Using Hitachi's MPD-EDIT software (Windows-based), engineers can design custom screens, assign function keys, and set up communication protocols. The software supports drag-and-drop creation of text displays, numerical entry fields, and alarm lists. Up to 100 screens can be stored in the unit's flash memory. Configuration files are downloaded via the RS-232 port.

Reliability and Environmental Compliance

Built for industrial use, the MPD060A withstands vibration, electrical noise, and temperature variations typical of factory floors. Its IP65 front panel ensures protection in wet or dusty environments. The unit is RoHS compliant and carries CE and UL marks for global acceptance.

The HITACHI MPD060A operator interface combines simplicity, durability, and low cost, making it the perfect choice for adding basic HMI functionality to any Hitachi-controlled machine.
