1. Introducció
This manual provides essential information for the installation, operation, and maintenance of the Kinco GL070 and GL070E Human Machine Interface (HMI) displays. These 7-inch TFT displays are designed for industrial control applications, featuring an ARM RISC 32Bit 800MHz CPU and 800x480 pixel resolution. The GL070 and GL070E models serve as direct replacements for the discontinued MT4434T and MT4434TE models, respectively, maintaining the same cutout size for easy integration.
2. Model Differences
The Kinco GL070 and GL070E models are largely similar in core performance but differ in their network connectivity options:
- GL070: This model does not include an Ethernet interface.
- GL070E: This model is equipped with a 10/100M adaptable Ethernet interface for enhanced network communication.
Both models are preferred for general use due to their non-hollow mask design, which offers better resistance against oil pollution, and their beautiful, ultra-thin body design. They are high cost-effective solutions for HMI applications.
