Intro Summary
Compact, rugged 2.8″ industrial HMI for machine operators needing a resolution-rich, IP65‑rated interface.
Product Overview
The MM‑13MR‑8MTS‑FE280D‑H3G‑A‑485 is a 2.8″ TFT touchscreen HMI featuring a crisp 320×240 resolution and resistive touch. Designed for industrial environments, its front‑panel IP65 rating ensures resistance to dust and splash. Interfaces include USB and TTL serial, plus support for RS‑485 communication. CE certified, and CE‑marked, it combines compact dimensions with reliable performance—ideal for OEM machines, automation panels, or embedded displays.
How to Use
Step 1: Mount the HMI into a 70×50 mm panel cut-out.
Step 2: Connect 12–24 V DC power to the V+ and GND terminals.
Step 3: Use USB or TTL for configuration/programming via PC.
Step 4: Connect RS‑485 to your PLC or motor controller using H3G or A‑485 port.
Step 5: Upload a UI project via supplied software and test touch interactions.
Tips: Ensure the panel seal is properly secured to maintain IP65 protection. Use shielded cables for RS‑485 to reduce interference.
