Brief Product Description

UNIOP ETT-VGA-0045 is a rugged industrial VGA HMI touchscreen panel built for factory automation machine visualization and operator control. Equipped with VGA display and resistive touch interface, this human-machine terminal establishes stable communication with PLCs to visualize real-time process data, trigger manual commands and display system alarms. It features a sealed front panel for dust and moisture protection, robust hardware and long product lifecycle for continuous plant operation. Supporting multiple industrial communication protocols, it delivers reliable monitoring and control for legacy automation equipment. Fully tested surplus and refurbished UNIOP ETT-VGA-0045 panels are available for HMI replacement, maintenance and retrofit projects on existing production lines.

FAQ (Frequently Asked Questions)

• Q: UNIOP ETT-VGA-0045 powers on but no display?
  A: Check 24VDC power supply and terminal wiring, inspect backlight condition, verify connector contact and check for damaged display circuits.
• Q: Touch screen unresponsive after installation?
  A: Confirm touch calibration, inspect touch wiring, check for physical damage on touch overlay and verify HMI project touch configuration.
• Q: Does ETT-VGA-0045 support hot-swap replacement?
  A: Hot swap is not allowed. Disconnect 24VDC power before removal to avoid communication errors and accidental machine actuation.
• Q: What PLCs can this HMI communicate with?
  A: It supports multiple serial industrial protocols to connect with major PLC brands commonly used in factory automation.
• Q: Is UNIOP ETT-VGA-0045 available for new automation projects?
  A: This legacy HMI touch panel is end-of-life for new projects. Only fully tested surplus and refurbished units are supplied for existing machine maintenance and retrofits.
