3.3 Power Supply and Electrical Parameters
Power supply voltage: 18~30 VDC, wide voltage input to adapt to power fluctuations in industrial sites.
Current consumption: Typical current is 0.25 A at 24 VDC, with extremely low power consumption.
Fuse: Built in automatic overcurrent protection, no external fuse required.
Battery: ePAD03 is equipped with CR2430 lithium manganese battery (3V, 270mAh) to maintain real-time clock operation, which can be replaced by users; EPAD04 does not have a real-time clock, therefore it is not equipped with a battery.

Software Features and Development Environment
4.1 Designer 6 Programming Software
EPAD03 and ePAD04 are programmed using Exor's powerful Designer 6 software. This software runs on the Windows environment and provides an intuitive graphical programming interface, supporting the following core functions:
Dual drive communication: ePAD03 supports dual drive communication capability and can communicate with devices of two different protocols simultaneously, such as connecting PLC and frequency converter to achieve data exchange. EPAD04 does not support this feature.
Rich communication driver library: Built in over 130 communication drivers, covering mainstream industrial equipment.
Scalable font: supports dynamic adjustment of text size to optimize information display effect.
Dynamic data display: supports dynamic data display in various formats such as numerical values, text, bar charts, graphic images, etc.
Formula data storage: ePAD03 supports formula data storage, facilitating parameter switching during batch production. Formula data can be uploaded to the host through an Ethernet module.
Multilingual application: Supports runtime multilingual switching, with the number of languages limited only by memory. All text information can be exported in Unicode format for easy translation processing.
Macro Editor: A powerful macro editor allows users to write response logic for events such as keystrokes and variable changes, enabling complex control functions.
Alarm and Event Management: Supports 1024 alarm records, and ePAD03 also supports a list of 256 historical events. The alarm information can be printed or uploaded to the host through Ethernet.
Password protection: Level 8 password protection ensures safe operation.
UniNet Network: ePAD03 supports UniNet client/server mode, can share data with other UniOP HMIs, and integrate with the upper computer system through UniNet OPC Server. EPAD04 only supports client mode.
Environmental adaptability and reliability
5.1 Temperature Range
EPAD03 and ePAD04 offer three temperature level options:
-0046 suffix: Standard working temperature range of 0~+50 ℃, suitable for ordinary industrial environments.
-00B6 suffix: Extended working temperature range of 0~+60 ℃, suitable for high temperature environments.
-00B7 suffix: Wide temperature working temperature -20~+60 ℃, suitable for cold regions or refrigeration equipment.
The storage temperature is -20~+70 ℃, which meets the needs of equipment transportation and long-term shutdown.
5.2 Humidity and Vibration
The working and storage humidity ranges from 5% to 85% RH (non condensing), which meets common requirements in industrial environments. The product design complies with EN 61000-6-4 (radiated interference) and EN 61000-6-2 (noise immunity) standards, ensuring stable operation in industrial sites with complex electromagnetic environments.
Mechanical installation and dimensions
6.1 Appearance and Hole Size
Panel size: 149 × 109 mm (5.86 × 4.29 inches)
Hole size: 136 × 96 mm (5.35 × 3.78 inches)
Installation depth: 53 mm (2.08 inches)
The compact size of the ePAD series makes it suitable for installation in control cabinets with limited space, compatible with the MD00 series size, and easy for old users to replace directly.
6.2 Installation precautions
To ensure IP65 protection level, attention should be paid to the following during installation:
The edge of the opening should be smooth and free of burrs.
Use the matching installation bracket and tighten it evenly.
Ensure good sealing between the front panel and the cabinet.
Comparison of ePAD03 and ePAD04 Functions
To help users quickly select, the main differences between the two products are compared below:
Function Item ePAD03 ePAD04
Real time clock with (battery backup) none
Recipe Memory 16 KB None
Event List 256 None
Dual drive communication support not supported
UniNet mode client/server client only
Battery CR2430 replaceable none
Programming speed 9600-38400 bps 9600 bps
From the comparison, it can be seen that ePAD03 is more functional and suitable for applications that require data recording, timestamps, and dual protocol communication; EPAD04, on the other hand, is more streamlined and suitable for pure monitoring and simple operation scenarios, with lower costs.
