8.4″ SLCD5+

Part Number: 51-0103-31

Powered by the SLCD5+ controller:

  • One RS232 and one RS485/RS422 serial port.

  • 266MHz ARM Processor. 28MB highly reliable NOR data Flash for user downloadable bitmaps with optional RLE compression. SD memory card slot for added flexibility. Audio beeper.

All 8.4″ modules feature:

  • Resistive touchscreens. Compare touch types.

  • Units combine a multi-function processor board and an industrial 8.4-inch wide viewing angle VGA (640×480) TFT color touch LCD.

  • Created especially for medical and industrial equipment that demands long avilability.

  • Designed for long-term availability with a 10+ year processor life and a multi-sourced, industry standard LCD form factor.

  • ESD and EMC results available to ease regulatory compliance testing.

  • Type: 4-Wire Analog Resistive
  • Durability: Over One Million Touches


8.10″ W x 5.99″ H x 1.28″ D


  • Operating Temperature: -20 to 70° C; the LCD temperature range primarily limits this
  • Storage Temperature: -30 to 70° C
  • Humidity: Max 90%RH at 60° C; No Condensation
  • RoHS 2 Compliant: Yes

Power Requirements

  • Power Supply Voltage: +12VDC±10%
  • Power Consumption: Max 900mA


The board mounting holes connect to a digital ground. These must be connected to a chassis ground either directly or through a transient protection diode for ESD. The resistive touch circuit has ESD protection that shorts ESD on the touch panel to the board mounting holes.
