S GD 24-M420 ORDERING INFORMATION Standard Display SGD 24-M420 Current Loop Indicator (Panel meter, fixing kit, quick star t guide) PanelPilot Compatible USB Cable CABLE USB A -MF (Type A to mini-B) Smar t Graphics Display USB Power Supply PSU-5VDC-USB-UK UK Plug USB Power Supply PSU-5VDC-USB-USA FEATURES USA Plug 2.4 colour TFT screen Use PanelPilot sof tware, to setup and customise the display. Compatible with Windows XP, Vista and Windows 7. Multiple configurations included free Programmable via the USB inter face Simple panel mounting solution Operating voltage of 4V-30V d.c. (see note) Measures 4 - 20mA current loop (also 10-50mA or 0-50mA possible) Digital hold The SGD 24-M is a PanelPilot Compatible graphics display with a 320 x 240 pixel (QVG A) colour display and USB programming inter face. Using the PanelPilot sof tware (available for Windows XP, Vista and Windows 7), user s are able to choose from an ever-increasing number of configurations (six voltmeter s at launch) which can then be customised to their needs. Colour s, text labels, splash screen and input scaling can all be customised by the user through the sof tware and then uploaded to the SGD 24-M through the USB connection. Panel or enclosure installation of the display is simple, using a panel fixing clip to mount the display, and 4 screw terminals to connect the inputs.

Typical Supply Current 200 100 0 4 17 30 Voltage (V) USB connection A Type A to Mini-B USB cable is required to program and customise the SGD 24-M. It typically takes 10 seconds to send a configuration, with an additional 5 seconds needed for the hardware to reset. The SGD 24-M can be powered directly from USB and is compatible with both USB 1.1 and USB 2.0. The screw terminals and advanced con- nector can remain connected whilst using USB, but it is not necessar y for V+ to be powered. A USB power supply is available - PSU-5VDC-USB-UK (UK plug format) or PSU-5VDC-USB-USA (USA plug format). This may be used as a con- venient means to provide a fully floating power supply for the loop indicator. Display The display is a 2.4 TFT panel, with a resolution of 320 x 240 pixels and a 16-bit color depth. Any graphics that are uploaded to the meter are automatically conver ted to this specification. A resistive touchscreen is fitted, for use with suppor ting applications. Clean the screen with a damp, sof t, lint free cloth. Panel Mounting The SGD 24-M can be fitted into panels of up to 3mm deep. A silicone seal is included to improve fitting on thin panels, however the maximum panel thickness is reduced to 2mm when fitted. Panel cut-out is 74 x 46mm. NOTE: The display is NOT protected against moisture or dust. www.lascarelectronics.com Specifications liable to change without prior warning Issue 1 10/2012 S.L Applies to SGD 24-M420 Page 2 of 5 Current (mA)
