Delta DOP-107EG DOP-100 Series 7-inch Ethernet High-Brightness HMI

Product Overview

The DOP-107EG (DOP107EG) is a high-performance 7-inch Human Machine Interface (HMI) from Delta’s advanced DOP-100 series. Featuring a crisp 800 x 600 pixel TFT LCD display with 65,535 colors and a high-brightness backlight (450 cd/m²), this terminal is designed for superior visibility in well-lit factory environments. Powered by an ARM Cortex-A8 800 MHz processor, the DOP-107EG offers rapid screen switching and smooth animation handling for complex automated systems. With its integrated 10/100 Mbps Ethernet port and built-in power isolation, it serves as a secure and versatile communication hub for modern "Smart Manufacturing" setups, providing a reliable bridge between operators and PLC-driven machinery.

Technical Configuration

The DOP-107EG belongs to the "Ethernet Cloud" category of the DOP-100 range, emphasizing connectivity and data security. It features three hardware COM ports supporting RS-232, RS-485, and RS-422 protocols, allowing for simultaneous communication with multiple industrial controllers. The inclusion of a 4-wire resistive touchscreen tested for over 10 million operations, combined with an IP65-rated front panel, ensures durability in oily or dusty conditions. Internally, the 256 MB RAM and 256 MB Flash ROM provide ample space for complex high-resolution graphics, historical data logging, and multi-language support.

Technical Specifications

Technical FAQs

How does the DOP-107EG handle power fluctuations?

The unit is designed for 24 VDC operation with a tolerance of +/- 15%. Crucially, it includes a built-in isolated power circuit for the Ethernet interface to prevent ground loops and protect the internal CPU from electrical noise common in industrial power grids.

What is the life expectancy of the backlight?

The LED backlight has a half-life of over 20,000 hours at a room temperature of 25 Celsius. To extend this lifespan, it is recommended to use the "Screen Saver" or "Auto-off" functions within the HMI software settings.

Can I log data to an external drive?

Yes. The DOP-107EG supports data logging and recipe storage to both its internal Flash memory and external media via the SD card slot or the USB Host 2.0 port (supports USB flash drives).

Engineering & Installation Guide

• Panel Mounting: Ensure the mounting cutout is exactly 172.4 x 132.4 mm. Use the supplied waterproof gasket and all mounting clips to achieve an IP65 seal. Tighten the clips evenly to avoid warping the HMI frame, which can lead to ghost touches on the resistive screen.

• Grounding Requirements: To comply with CE/UL standards and ensure stable communication, the FG (Frame Ground) terminal must be connected to a high-quality industrial ground. Always use shielded network cables and, as per manufacturer specifications, install a magnetic ring with a filter of 300 ohm / 100 MHz for optimal EMI suppression.

• Power Isolation: Although the HMI has built-in protection, it is an engineering best practice to use a dedicated 24 VDC isolated power supply (Class 2 or SELV) that is not shared with inductive loads like large contactors or solenoid valves to prevent voltage spikes from affecting the HMI's Cortex-A8 processor.
