Current Loop Indicator PanelPilot Compatible Smart Graphics Display Features • • • • • • • • 2.8” colour TFT screen Use PanelPilot software, to setup and customise the display. Compatible with Windows 7, 8.1 and 10. Multiple configurations included free Programmable via the USB interface 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 28-M is a PanelPilot Compatible graphics display with a 320 x 240 pixel (QVGA) colour display and USB programming interface. Using the PanelPilot software (available for Windows 7, 8.1 and 10), users are able to choose from an ever-increasing number of configurations (six voltmeters at launch) which can then be customised to their needs. Colours, text labels, splash screen and input scaling can all be customised by the user through the software and then uploaded to the SGD 28-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 USB connection A ‘Type A to Mini-B’ USB cable is required to program and customise the SGD 28-M. It typically takes 10 seconds to send a configuration, with an additional 5 seconds needed for the hardware to reset. The SGD 28-M can be powered directly from USB and is compatible with both USB 1.1 and...

Current Loop Indicator PanelPilot Compatible Smart Graphics Display Current Loop Internally the SGD 28-M420 uses a Programmable Gain Amplifier (PGA) to make the best use of available resolution (theoretically there are eight different ranges available to the SGD. However for the 4-20mA application, this is effectively restricted to the 0-2.5 range. Voltage Range (V) The input voltage range is decided using the two voltages that the user enters in the scaling section of the Panel Pilot software. The software uses the smallest range available, which can accommodate both of the voltages entered...
