Product Description:

The Data-Chart 2000 has 2, 4, 6 or 12 direct universal isolated inputs that are menu-selectable for DC voltage, DC current and thermocouples. The intuitive Touchscreen control provides easy, fast set up and operation.

Display: Our brilliant 5.6″ (142mm) active matrix TFT color display is the largest in it’s class and with a special anti-glare coated Touchscreen the viewability is second to none. If you need a more economical solution, the DC2000 can also be ordered with a super bright blue monochromatic display.

Recording: Data is stored in non-volatile internal RAM and downloaded to removable media automatically on a preset basis or on demand. Standard removable storage is a 3.5″ 1.44Mb disk or, for large amounts of data, you can choose the PCMCIA card drive option which will store up to 200 Mb of Data.

Speed: A measurement rate of 8 samples per second for 1 channel makes the DC2000 ideal for recording process signals that change quickly such as pressure. Or, if you require information less frequently, you can select to record between 8 samples per second and ten minutes.

Communications: Communication options offer great flexibility in accessing data or controlling the DC2000. Data can be accessed and downloaded over standard phone line using the RS232C option and a modem. The RS485 MODBUS option will allow the DC2000 to be installed into an existing MODBUS network or you can connect up to thirty one recorders in series. The 10BaseT Ethernet port option allows direct connection to LAN’s or WAN’s and the standard TCP/IP protocol means that you can transfer data over the Internet.

There are more than 20 display modes to choose from. This gives you unparalleled flexibility to view only the data you need to see in virtually any format. Grouping of channels maximizes efficiency.
