The 256-color palette is adequate for status screens and alarm pages but falls short of the 65K-color TFT panels in the GOT2000 line — expect blockier gradients on process graphics. The cold cathode (CCFL) backlight carries a 5-year life at 25°C ambient and is not user-replaceable. When the display dims or flickers, the entire GOT body must be swapped — plan a replacement window around year 4 in a climate-controlled cabinet, sooner if the panel sees sustained 50°C vertical mounting. ## Serial connectivity for legacy PLC links One RS-232 channel on a D-sub 9-pin male connector handles short-distance programming and PLC links up to 15 m at baud rates from 4800 to 115200 bps. The RS-422 port on a D-sub 9-pin female extends that reach to 1200 m for remote I/O or multi-drop configurations — the HMI can talk to a Mitsubishi FX or Q-series PLC on one port while logging to a printer on the other. A USB Mini-B device port provides Full-Speed 12 Mbps transfer for project downloads from GT Designer3. This is the primary method for screen uploads on a laptop — the serial ports are typically reserved for runtime PLC communications, not commissioning. ## Mature lifecycle — sourcing through independent channels The GT1055-QSBD carries a mature lifecycle status. Mitsubishi has moved focus to the GOT2000 series for new designs, but this HMI remains orderable through independent distribution for existing machine builds and MRO swaps. No official successor order code is published — the GOT2000 equivalent requires a different project file and panel cutout. The 128 KB SRAM holds clock data, alarm history, recipe data, and time-action set values backed by a GT11-50 BAT lithium battery. The battery is field-replaceable; the CCFL backlight is not. Factor both into the preventive maintenance schedule for installed units. ## Panel cutout and environmental limits Operating temperature range is 0 to 55°C in horizontal mounting, derated to 0 to 50°C when mounted vertically. Pollution degree 2 (non-conductive dust only) and 2000 m elevation limit apply — no oil mist, corrosive gas, or direct sunlight. The self-cooling design means no fan to fail, but the enclosure must allow natural convection around the rear case.","metaTitle":"Mitsubishi GT1055-QSBD GOT1000 HMI, 5.7\" QVGA STN","metaDescription":"Mitsubishi GT1055-QSBD GOT1000 Series touch screen HMI. 5.7-inch QVGA STN color LCD, 256 colors, RS-232/RS-422 serial ports, USB Mini-B.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["HMI Operator Interfaces"],"specifications":{"Color":"White","title":"GT1055-QSBD","Ground":"D class grounding (100 O or less), connection to the board when grounding is not possible","RS-232":"Number of channels: 1ch Transmission rate: 115200/57600/38400/19200/9600/4800 bps Connector shape: D-sub 9-pin (male)","RS-422":"[H / W version: A to B] Number of channels: 1ch Transmission rate: 115200/57600/38400/19200/9600/4800 bps Connector shape: D-sub 9-pin (female)","Series":"GOT1000","Weight":"0.7kg (Excluding mounting fixtures)","Category":"GOT body","Key size":"Minimum 16 x 16 [dot] (per key)","Lifespan":"About 5 years (operating ambient temperature: 25 ° C)","Resolution":"QVGA: 320 × 240 [dots]","Product No.":"GT1055-QSBD","Screen size":"5.7 type","description":"GOT1000 Series, Touch Screen HMI Panel","Battery type":"GT11-50 BAT type lithium battery","Display size":"115 (W) x 86 (H) [mm] (horizontal display)","Display type":"STN color liquid crystal","Memory board":"For connecting GT10-50FMB type memory board","Product type":"GOT1000 Series, Touch Screen HMI Panel","USB (device)":"Number of Channels: 1ch Maximum Transfer Speed: Full-Speed ??12Mbps Connector Shape: USB Mini-B","Backup target":"Clock data, alarm history, recipe data, time action set value","Buzzer output":"Single tone (adjustable long / short / no)","Display color":"256 colors","Mounting type":"standard","SRAM capacity":"128KB","Use elevation":"2000 m or less","Viewing angle":"Left and right 55 degrees, upper 65 degrees, lower 70 degrees (horizontal display)","Backlight type":"Cold cathode tube (not user-replaceable) Backlight burnout detection with back light OFF / Screen save time configurable","Classification":"Medium size: 4.7 to 7","Cooling Method":"Self-cooling","Inrush current":"15 A or less (2 ms, at maximum load)","Use atmosphere":"No oil smoke, corrosive gas, flammable gas, no conductive dust, no direct sunlight (same as storage)","Noise tolerance":"By noise simulator of noise voltage 1000Vp-p, noise width 1µs, noise frequency 30 to 100Hz","Shipping Weight":"8 Kg","lifecycle_stage":"mature","Pollution degree":"2 or less","Shock resistance":"Conforms to JIS B 3502 and IEC 61131-2 (147 m / s 2 , X, Y, Z directions 3 times each, action time 11 ms)","Touch key number":"50 pcs / 1 screen","Withstand voltage":"Between power terminal package and ground AC500V for 1 minute","Life (write count)":"100,000 times","Other than display":"0 to 55 ° C (horizontal), 0 to 50 ° C (vertical)","Touch panel method":"Matrix resistive film type","Applicable standard":"UL / cUL, CE (EMC), CE (RoHS), KC","Contrast adjustment":"16 levels adjustment","Estimated Lead Time":"Usually ships in 1 - 10 working days.","External dimensions":"164 (W) x 135 (H) x 56 (D) [mm]","Applicable wire size":"~ 2 0.75 [Mm 2 ]","Overvoltage category":"Less than II","Panel cut dimensions":"153 (+2-0) (W) x 121 (+2-0) (H) [mm]","Protective structure":"Equivalent to IP67F (JEM1030) (front part)","Installation location":"Control panel inside","Insulation resistance":"10 MO or more with power terminal collective ?
