## **SGD 70-A** 

## 7” PanelPilotACE Compatible Display 

SGD 70-A is a 7” capacitive touch display designed for use with PanelPilotACE Design Studio, a free drag-and-drop style software package for rapid development of advanced user aa a Pe Pay -_— = interfaces and panel meters. 

The SGD 70-A is part of the PanelPilotACE range of compatible displays and panel meters. The low-profile display features a 7” capacitive touch screen and a dual-core ARM processor running embedded Linux. The display can be powered from a 5 to 30V d.c. supply and offers users a wealth of hardware interfaces which include four 16bit bi-polar analogue inputs (to a maximum of ±40V d.c.), eight digital input/output pins, two alarm outputs (maximum current sink 10mA) and four 8bit PWM outputs. 

Users program the display using the free PanelPilotACE Design Studio software which allows the creation of anything from simple meters and dials, through to advanced user interfaces with control elements.

## PanelPilotACE Design Studio 

## **Code-Free development for industrial display projects** 

The PanelPilotACE Design Studio software provides a number of building blocks which allow users to drag-and-drop elements onto the screen to quickly create advanced display interfaces. From images to text elements, analogue style meters, touch screen navigation elements, logic statements, data logging, trend graphing and calculations, users can build up multi-screen interfaces without needing to write a line of code. 

There is a library of pre-defined elements such as meters, buttons and switches, and users can create their own content by combining elements or importing graphics in a number of formats (including jpg, png, tif, bmp and gif). The software includes support for transparency and multiple layers. 

Hardware interfacing is similarly intuitive, with hardware elements being dragged into a function builder where associations with graphical elements (such as a needle on a meter) can be defined. Here users can determine scaling for analogue inputs, define alarm triggers, behaviours for digital inputs and outputs and configure PWM outputs. 

## **PID Control:** 

Use your display as a PID control unit. Set P, I and D coefficients, measure a process variable and use PanelPilotACE to correct to your desired set point. 

## **Easy Collection of Logged Data:** 

Easily collect logged data by connecting the PanelPilotACE via USB to a PC running Design Studio or Device Utility Software, or connect to an FTP Server via wired Ethernet. 

## **Multi-Channel Data Logging:** 

10 logging channels allowing logging of any input to the device that can be defined numerically. 

## **Trend Graphs:** 

Display data on graphs as it is logged. If you use an alarm threshold as one of your data channels,  monitor logged data against alarm levels. 

## **Previewing and Uploading Projects:** 

The software includes a ‘Preview in Emulator’ function which emulates the hardware’s inputs and outputs, allowing users to test their projects prior to upload. Projects are uploaded to the SGD 70-A via a mini USB port. 

**PanelPilotACE Design Studio is compatible with Windows 7, 8 and 10 and can be downloaded free from www.lascarelectronics.com/software/panelpilotace**

## Panel Cut-Out and Fitting 

The panel cut-out is 180 x 117mm (7.1” x 4.57”). 

The module can be mounted in panels between 0.5 and 4.0mm (0.01” and 0.15”) in thickness. 

To do this take the four bracket clips supplied and use the screws to secure these to the mounting holes located on the rear of the module. 

Then place the module in the panel and tighten the grub screws located in each bracket to secure the module within the panel.

## Various Operating Modes 

## **Supply Voltage** 

Supply to the display module can be connected to either the screw terminals (TB1) or pins (PL4) 

For best results, ensure the power supply is free from electrical noise.

## **Measuring an Analogue Voltage** 

An analogue voltage can be connected to either the screw terminals (TB1) or pins (PL11). 

|**Analogue Input**|**Analogue Input**|**Screw Terminals**|**Pin (PL11)**|
|---|---|---|---|
|||**TB2**||

||0V|0V|6|
|4|IN4|IN4|7|
||0V|0V|8|



To minimise offsets it is best practice to connect analogue grounds directly to the meter pins (PL11) or screw terminals (TB1). 

The SGD 70-A uses a programmable gain amplifier (PGA) together with a 16-bit analogue to digital converter (ADC) for its analogue voltage measurements. The PGA is automatically set when the analogue range of a channel is input into the PanelPilotACE Design Studio.

## Various Operating Modes (continued...) 

## **Measuring a 4-20mA Current** 

The 4-20mA signal should be connected as for “Measuring an Analogue Voltage” but a jumper link should be placed across pins PL8 for each analogue channel being used: 

|**Analogue Voltage**|**Jumper link (PL8)**|
|---|---|
|IN1|1 & 2|
|IN2|3 & 4|
|IN3|5 & 6|
|IN4|7 & 8|

Scaling: The sense resistors used are 110Ω. Therefore in software scaling 4mA equates to 0.44V and 20mA equates to 2.2V. 

Note: transmitter terminals (+ or -) must be isolated from the power supply 

## **Driving an Alarm Output** 

The alarm outputs are open-collector. When an alarm is active, the output can sink up to 10mA. 

Alarm outputs are connected via PL4:

For maximum flexibility in accommodating external add-on boards and interfacing to external circuits, the digital I/O pins connect directly to the microcontroller and do not contain any buffering or protection circuitry. Take care not to exceed the maximum ratings, otherwise the unit may be permanently damaged. 

If there is a risk that inputs may exceed these values, then voltage limiting must be used (example circuit above). Note that the protection diodes must be of the Schottky type and not regular silicon diodes.
