Introduction: Solving Analog Video Integration in HMI Systems
When a manufacturing line requires operators to monitor analog camera feeds directly on the HMI, the Mitsubishi GT27-V4-Z Video Input Unit provides a seamless solution. Part of the GOT2000 series, this unit is specifically designed for GT27 models, eliminating the need for separate monitors or complex cabling. It accepts analog video signals and displays them on the connected GOT2000 series HMI, streamlining operator interfaces in industrial environments.
Technical Specifications Breakdown
The GT27-V4-Z offers four input channels, each capable of displaying one video input at a time. It accepts composite video signals in NTSC and PAL formats, ensuring compatibility with standard surveillance and inspection cameras. The synchronization signal requires 1 Vp-p at 75 Ω impedance, matching typical video equipment outputs. Display resolution reaches 640 x 480 pixels (VGA), suitable for general monitoring tasks like machine vision or security feeds. Connection uses BNC connectors, a robust standard for video signals. Current consumption is approximately 0.32 A at 3.3 V DC and 0.34 A at 5.0 V DC, indicating efficient power usage.
Industry Applications
In automotive assembly lines, the GT27-V4-Z enables operators to view camera feeds of weld joints or part alignment directly on the GT27 HMI, reducing the need for separate displays. For packaging facilities, it allows real-time monitoring of label placement or fill levels, improving quality control. The 4-channel design supports multiple camera angles, while VGA resolution provides clear images for inspection tasks.
Installation & Setup Guidance
Mount the GT27-V4-Z securely within the control cabinet, ensuring adequate ventilation. Connect BNC cables from analog cameras to the unit's input ports. Verify the synchronization signal meets 1 Vp-p at 75 Ω. Power the unit via the GOT2000 backplane; current draw is 0.32 A at 3.3 V DC and 0.34 A at 5.0 V DC. Configure the HMI software to select the desired video channel for display. For best results, use shielded coaxial cables to minimize interference.
Maintenance & Reliability
Periodically inspect BNC connectors for corrosion or loose connections. Clean the unit's exterior with a dry cloth; avoid solvents. The GT27-V4-Z is designed for continuous industrial operation, with efficient power consumption reducing thermal stress. Regular firmware updates for the GOT2000 series ensure ongoing compatibility.
Compatibility & Integration
The GT27-V4-Z integrates exclusively with the GOT2000 series and is compatible with GT27 models. It works with standard composite video sources (NTSC/PAL). For extended functionality, pair with the GT27-IF1000 interface converter (weight 0.34 kg). No additional communication protocols are required for video input.
Selection Guide & Purchasing Advice
Before ordering, verify your HMI is a GT27 model within the GOT2000 series. Confirm your cameras output composite video (NTSC or PAL) with 1 Vp-p sync. The unit weighs 3.00 lbs (1.36 kg) standalone; with the interface converter, total weight is 0.34 kg. SpareTechPLC stocks the GT27-V4-Z and can advise on availability and lifecycle status.
