Information
Overview
Manuals
Common Applications
Product Precautions
MT8121IE provides 12.1-inch industrial visualization, resistive touch operation and multi-interface controller communications for an EasyBuilder Pro project.
- 12.1-inch 1024 x 768 TFT display
- 4-wire resistive touch panel
- 600 MHz Cortex-A8 processor
- Isolated RS-485, Ethernet, USB and SD connectivity
The HMI must remain matched to the selected MT8121iE target, project file, controller drivers and every serial, Ethernet, USB and SD assignment. Commissioning verifies boot, communications, screen behavior, alarm functions and retained data.
Important Notice: Confirm MT8121IE/MT8121iE, EasyBuilder Pro target and project, 24 Vdc supply, protective earth, COM1/COM3 wiring and isolation, Ethernet addressing, USB/SD use and controlled interface-test evidence before commissioning.
Weintek MT8121IE Manuals & Downloads
These documents are different: the first consolidates model-specific technical and system data; the second is the official manufacturer datasheet for MT8121iE.
Machine visualization
Displays process values and documented operating states.
PLC operator station
Provides touch commands through configured controller drivers.
Alarm and data handling
Supports project alarms, logs, recipes and retained records.
Legacy panel replacement
Restores the exact MT8121iE target and interface setup.
Read the applicable Weintek installation instructions before work. Verify MT8121IE, the installed host system and all configured field interfaces before isolation, wiring or commissioning.
1
Confirm MT8121IE and the manufacturer MT8121iE identity on the label.
2
Place the machine and connected controller in the approved maintenance state.
3
Back up the EasyBuilder Pro project, recipes, logs and retained data.
4
Record 24 Vdc polarity, protective earth, COM1/COM3 modes, Ethernet, USB and SD use.
5
Isolate power and protect the resistive touch surface and all connectors.
6
Restore the MT8121iE project target, controller drivers, addresses and isolated serial assignments.
7
Review boot, CPU/COM indicators, communications and alarms after energization.
8
Test representative tags, commands, alarms, data entry and retained settings before release.
Alternative Names
