Description
Designed for mobile operation and direct machine-side control, the GT1155HS-QSBD serves as a rugged, handheld human-machine interface (HMI) within the Mitsubishi Electric GOT1000 platform. This "Handy" series operator terminal integrates physical tactile controls and high-reliability safety features directly into the portable housing, making it optimal for manual machine setups, teaching operations, and local debugging tasks.
The unit features a bright 5.7-inch STN color display with a QVGA resolution of 320 x 240 pixels. To ensure safe operation in manual mode, the device incorporates physical operator controls, including six application switches, a key-operated selector switch, and a three-position grip switch (enabling/deadman switch). Equipped with multi-channel serial connectivity and storage expandability via CompactFlash, this terminal interfaces seamlessly with MELSEC PLCs and other industrial controllers.
Features
-
Industrial Handy Form Factor: Mobile design engineered for safe, tethered hand-held operations in demanding environments.
-
Integrated Safety Elements: Built-in 3-position grip switch (OFF-ON-OFF) and a 2-position key selector switch for secure operator authorization.

Installation Guidelines
-
Cable Management: Route the 32-pin system cable away from high-voltage AC lines or motor power cables to minimize electromagnetic interference (EMI).
-
Port Protection: Ensure the rubber environmental caps are securely sealed over the Mini-DIN and USB ports when not actively connected to a configuration PC to maintain the IP65F rating.
-
Grounding: Connect the dedicated functional ground conductor in the host-side cable assembly to a low-impedance industrial ground point.
-
Operating Environment: Avoid exposing the HMI display panel to direct sunlight for prolonged periods to prevent thermal buildup and localized polarization of the liquid crystal layer.
