UniOP MD02F-02 and MD02R-04 Compact Low Cost Industrial HMI Equipment

Product Core Positioning and Basic Design

Both devices are compact and low-cost industrial HMIs, integrating 9 function keys and a numeric keypad, with rich functions and suitable for small-scale installation needs in industrial sites;

Core hardware design: 9 user programmable function keys (with slide in legend), 10 user programmable LED indicator lights, front panel protection level up to IP65, supporting multilingual project development;

Expansion capability: Industrial fieldbus and Ethernet connections such as Profibus DP/DeviceNet can be achieved through optional modules, compatible with all standard TCM/SCM expansion modules.

Display core specifications

The only difference between the two devices is the display type. The LCD screen is equipped with a long-life LED backlight, and the core display parameters are clearly presented in a table:

Model Display Type Column Number Character Height Backlight/Lifespan Contrast Adjustment User defined Characters

MD02F-02 VFD (Vacuum Fluorescent Screen) 2 × 20 5mm without —

MD02R-04 monochrome LCD 4 × 20 5mm LED/100000 hours software adjustment 8

Hardware core configuration

（1） Button and LED indicator light

Button: 9 user programmable function keys+10 system keys, function keys 1-9 with slide in legend, key RDA mapping to industry standards;

LED: 9 user LED indicator lights+2 system LED indicator lights (green DL+red FL), system LED corresponds to device operation, communication, battery, hardware failure and other status.

（2） Memory and Storage

User memory: comes standard with 512 KB, supports 512 KB expansion, and the total memory after expansion reaches 1MB;

Recipe storage: Exclusive 16 KB memory, supporting reading, writing, and storage of recipe data;

Variable support: There is no limit to the number of variables per page, meeting the needs of industrial multi data monitoring.

（3） Clock, battery, and peripherals

Equipped with hardware RTC (real-time clock), powered by CR2430 lithium battery, with a battery parameter of 3V 270mA, non rechargeable, user replaceable, and replacement needs to match the operating temperature of the device;

No screensaver, no buzzer, no external keyboard port, lightweight design.

（4） Power supply, insurance, and weight

Power supply voltage: 18~30 VDC, maximum power consumption of 0.25 A at 24VDC, lower power consumption and more energy-efficient;

Fuse: 2A replaceable fuse provides overcurrent protection for equipment;

Equipment weight: about 0.9 Kg, much lighter than other HMIs in the same series, suitable for lightweight installation.

（5） Communication Interface and Programming

Standard interfaces: PC/printer port+PLC port (supports RS-232, RS-422, RS-485, 20mA current loop), auxiliary port (requires optional module to achieve fieldbus/Ethernet);

Programming speed: 9600~38400 bps, standard programming cable CA114, can be used directly.

Core functional characteristics

All functions are implemented using UniOP Designer software, which combines industrial compatibility and practicality. The key functions are as follows:

Communication capability: Supports communication drivers for over 130 types of industrial equipment, with unique dual driver communication capabilities, greatly improving communication compatibility with different industrial equipment;

Data display: supports dynamic data display in three formats: numbers, text, and bar charts, adapting to the diverse data monitoring needs of industrial sites;

Security protection: equipped with an 8-level password protection mechanism to prevent unauthorized personnel from operating critical system functions, ensuring industrial production safety;

Alarm management: Supports 1024 alarm monitoring channels, automatically retains a list of 256 historical events, with a dedicated alarm information page for intuitive viewing of alarm details;

Network and Editing: Equipped with UniNET network, supporting Client/Server mode, realizing multi HMI data sharing; Equipped with keyboard macro editor, customizable function key operation logic; No data collection and trend analysis function.

Environmental adaptation and industrial certification

Protection level: IP65 protection for the front panel, dustproof and waterproof, suitable for complex physical environments in industrial sites;

Temperature and humidity adaptation: divided into 3 temperature zone versions, with a storage temperature of * * -20~70 ℃ and a working humidity of 5~85% RH (non condensing) * *. The specific working temperatures are as follows:

-0045/-0050 version: 0~+50 ℃ (standard temperature range)

-00A6 version: 0~+60 ℃ (extended temperature range)

-00A7 version: -20~+60 ℃ (fully expanded temperature range)

Industrial certification: Compliant with EU electromagnetic compatibility standards, emitting interference EN 61000-6-4:2001 and anti-interference EN 61000-6-2:2001, meeting the electromagnetic environment requirements of industrial sites.

Physical installation dimensions

The installation dimensions of the two devices are completely unified and suitable for standardized industrial opening installation. The specific parameters are:

Panel size (length x height): 195 x 98 mm (7.67 x 3.85 inches)

Hole size (A × B): 174 × 78 mm (6.85 × 3.43 inches)

Hole depth: -0045/-00A7 is 74 mm (2.91 inches), -0050 is 82 mm (3.20 inches)

Maximum panel thickness: 5 mm (0.20 inches)

System LED indicator light description

The front is equipped with two system LEDs, green DL and red FL, which correspond to different device information in different states and provide intuitive feedback on device operation

Meaning of LED identification color status

DL green off, no button operation and no device error

DL green flashing communication error

DL green constant light with button operation (visual feedback)

FL red goes out without hardware malfunction, battery level is normal

FL red flashing, low battery level

FL red constant on hardware malfunction
