GT1275-VNBA at a glance
The Mitsubishi Electric GT1275-VNBA is a 10.4 in TFT touch-screen HMI in the GOT1000 series, displaying 640 x 480 pixels (VGA) in 256 colors across a resistive touch overlay. It runs from 100 to 240VAC supply, so it drops straight into the same single-phase control circuit that feeds most control cabinets without a separate 24VDC PSU on the DIN rail.
Resolution, color depth, and what the screen tells the operator
640 x 480 on a 10.4 in diagonal is the workhorse VGA footprint of the GOT1000 generation — plenty of room for trend screens, alarm summaries, and recipe selectors without forcing the designer into the higher pixel counts that newer wide-format panels demand. 256-color TFT is enough to differentiate status blocks and alarm states; it is not a true-color part, so any screen layout that relies on photographic shading for operator guidance will read flat. 100 to 240VAC input is the headline for cabinet builders — no 24VDC conversion kit is needed, and the same panel can be wired off the same isolation transformer as a small inverter or a contactor coil circuit.
Mature line, independent sourcing
Mitsubishi Electric classifies the GT1275-VNBA as a mature-stage product — it is past its primary deployment window but remains orderable through the independent channel for installed-base spares and legacy panel builds. Independent distribution handles the mature-line posture: each RFQ pulls current stock, lot, and condition data so the buyer can confirm what they are getting before the BOM line is committed. Lead time is short — typically days rather than the multi-week waits a true phase-out attracts.
