Weintek MT8071iE

The Weintek MT8071iE is a high-performance 7-inch widescreen HMI from the iE Series. It is one of the most popular models in the Weintek lineup because it balances a compact form factor with advanced networking capabilities, specifically built-in Ethernet.

It is widely used in complex automation systems where the HMI needs to communicate with multiple PLCs over a network or provide remote access.

1. Display and Visuals

The “iE” series offers a significant upgrade in color depth and clarity over the basic “iP” models.

• Screen Size: 7-inch Widescreen (16:9).

• Display Type: TFT Color LCD.

• Resolution: 800 x 480 pixels (WVGA).

• Colors: 16.7M colors (24-bit), providing vivid graphics and smooth color gradients.

• Backlight: LED with a lifespan of approximately 30,000 hours.

2. Connectivity and Ports

The standout feature of the MT8071iE is its robust connectivity suite:

• Ethernet Port: 1x RJ45 (10/100 Base-T). This allows for high-speed PLC communication, remote monitoring (VNC), and multi-HMI networking.

• COM 1: RS-232 / RS-485 (2-wire or 4-wire).

• COM 3: RS-485 (2-wire).

• USB Host: 1x USB 2.0 port for connecting a flash drive (data logging, recipes, or project backup).

• USB Client: Not available (programming is typically done via Ethernet or the USB Host port).

3. Hardware Performance

• Processor: 32-bit RISC 600 MHz CPU.

• Memory: 128 MB Flash and 128 MB RAM.

• PCB Coating: The internal circuit boards are Conformal Coated, providing excellent protection against humidity, dust, and corrosion in harsh industrial environments.

• Isolation: Features built-in power isolation to prevent damage from electrical surges or ground loops.
