The D300 is an all-new lower cost data acquisition platform. It is a stand-alone system that has its own computer inside, with a 500 GB removable HDD, plus ethernet and USB interfaces. There's no display, but you can attach any standard one, or use an IPad3 to control the system wirelessly!
  • Built-in powerful computer
  • Removable 500 GB HDD on the rear panel
  • Includes DS-7-SE software
  • Lowest-cost DEWE platform
  • Universal signal conditioners (STG)
  • Optional iPad3 and RDP application for remote control
  • 100% DEWETRON at half the price

Here is an assortment of photos of the D300, so you can look at this product from a variety of angles. We show the D300 with a separate desktop display, as well as with the New iPAD from Apple, as a remote display and controller.

The D300 can be configured with 8 or 16 MDAQ conditioning channels right on it. Then there is a 32 channel model where the first 16 channels are installed into the D300, and the other 16 are in a small external box that connects via a cable.
Stacks Image 18659
The most common configuration of the D300 is with 16 MDAQ channels. There are several MDAQ conditioner types to choose from. Each one provides a block of 8 channels.
Stacks Image 18662
The rear panel of all D300 (and D3PC) models features a door that protects the computer connections (multiple ethernets, four USB 2.0, RS232, VGA output, and more), plus the DC power input, and the 500 GB removable HDD.

Filtered air is drawn in on the left side, and forced out the right side. All filters can be accessed from the OUTSIDE of the system - no need to open it up.
Stacks Image 18668
The D300-MDAQ can also be fitted with a 32-channel A/D card inside. In this case, the mainframe contains the first 16 MDAQ channels, and a small expansion box contains the next 16 channels. A one meter connecting cable is included.

With the D300 connected to a WIFI network, and a RDP application installed properly, you can use the new iPad from Apple as a convenient remote touchscreen display.

WIFI can be installed into any D300 series model (including the smaller footprint D3PC variants). Rear panel shown with the antenna.

All D300 models run from a very wide range DC input power: 9 to 29 VDC. This makes it easy to use in mobile applications, and reduces the overall weight of the system for any application.
SC4 series signal conditioners provide up to 10 kHz bandwidth, as well as 1500V isolation and 240VRMS common mode voltage. SC4 are available for voltage, current, bridge, RTD, and thermocouples.
The D3PC platform is roughly half the width of the D300-16, making it the smallest stand-alone DEWE systems in their class. The BNC inputs are located right above the removable HDD.

MDAQ series signal conditioners provide up to 300 kHz bandwidth, as well as up 250 VRMS common mode voltage. MDAQ conditioners are available for voltage, strain, and accelerometers.
All D300 and D3PC models feature a 500 GB removable hard disk drive, making them convenient to use in classified data applications. Also data back-up is easier than ever before.
DS-7-SE software is included in all D300 and D3PC models. Setup, capture, and analysis is built-in and easy. Create whatever screen you want, export to multiple formats, and more.
Wireless control using the New IPAD
Of course you can plug in a regular VGA display to the D300 series: the rear panel has a door behind which are connectors for a monitor, several ethernet ports, four more USB 2.0 ports, and more.

But in addition, you can upgrade the system to have a WIFI interface - and then use the new IPAD from Apple as a wireless display.

You can buy the whole setup as an option for your D300 (any model), and we will add the WIFI hardware, new IPAD, and remote desktop client for you.

32-channel Systems
The D300 can be configured with 32 dynamic input channels. In this case, half of the channels are located on the front panel, and the other half are located on a small box that connects to the system by a 3 foot long cable.

Note - this requires that you upgrade the A/D card to a 32-channel model. See the available A/D upgrade options below. There are 32-ch cards with 16-bit or 22-bit resolution, and max sample rates of 100 kS/s/ch.
