Kinco GL070E and Samkoon 7-inch HMI: model-level selection guide
Compare Kinco GL070E with Samkoon EA-070B V4 and SK-070QE V3 by display, Ethernet, serial ports, cut-out and project migration.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
EA-070B V4 and SK-070QE V3 can be evaluated within the same 7-inch/800×480 selection intent as GL070E; this does not imply physical or software compatibility. Ethernet, serial ports, panel cut-out, brightness and rebuilding the existing project are verified per exact model.

ProControl products to evaluate first
The exact configuration is selected after engineering review.
SK-070QE V3
7-inch 800×480 candidate in the two-serial-channel class; the official model data lists no Ethernet.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | Kinco GREEN Series GL070E | Samkoon / ProControl candidate |
|---|---|---|
| Display class | Kinco's official page defines GL070E as a 7-inch, 800×480 TFT HMI. | EA-070B V4 and SK-070QE V3 are listed on official Samkoon pages as 7-inch, 800×480 models; similar visible area alone is not a selection decision. |
| Ethernet | GL070E network interface and functions are verified from the exact GL070E hardware record. | The official SK-070QE V3 page lists Ethernet as 'NO'; networking is not assumed for EA-070B V4 either. If Ethernet is mandatory, another Samkoon model is selected. |
| Serial communications | GL070E serial-interface standards, isolation and simultaneous-use rules are checked in the official pin/port table. | EA-070B V4 lists RS232/485/422 on COM1; SK-070QE V3 lists RS232 and RS485/422 channels. The PLC driver and pinout are confirmed separately. |
| Panel cut-out and depth | GL070E external dimensions, cut-out, mounting depth and connector clearance are the reference for the existing panel. | Samkoon drawings are overlaid directly; an adapter plate and cable rearrangement are designed if needed. The label '7-inch' does not establish cut-out compatibility. |
| Software and project | The Kinco HMI project is built with Kinco's engineering environment, objects and PLC drivers. | Samkoon screens are rebuilt in SKTOOL; images, addresses, alarms, recipes, trends and user access are revalidated. |
| Environmental and acceptance criteria | GL070E brightness, front IP, temperature, supply and EMC values establish the minimum for the existing application. | The same headings for the Samkoon candidate are compared from the exact data sheet; sunlight, gloves, noise, restart and communication loss are field-tested. |
Suitable scenario
When is it worth evaluating?
- Simple machine projects needing a local 7-inch/800×480 HMI
- Applications where serial communication is sufficient instead of Ethernet, or networking can be redesigned
- Modernisations open to a new panel cut-out and rebuilt screen project
Migration gate
Before making a decision
- Record exact GL070E port, pin, Ethernet, supply and cut-out information.
- Inventory the existing project's PLC driver, tag count, alarms, recipes and trends.
- Compare EA-070B V4 and SK-070QE V3 drawings to the existing panel at scale.
- Verify serial electrical mode, pinout, grounding and communication speed.
- Test brightness, touch, restart, data writes and communication loss during FAT.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Does being 7-inch and 800×480 mean it can be installed directly in place of GL070E?
No. Cut-out, enclosure depth, connectors, pins, software and protocol driver may differ; exact drawings and a working-machine test are required.

This content compares manufacturer-published data under the same project requirement; it does not guarantee direct substitution or project compatibility. ProControl engineering must validate exact model, revision, protocol, electrical, safety and environmental conditions.
