The DataChart 1250 is a feature-rich data acquisition system offering 2 universally-configurable inputs for measuring DC voltage, DC current, thermocouples, and RTDs as well as frequency and pulse inputs. Four (4) internal alarm set-points, 2 alarm relay output,s and 1 digital control input are standard. A maximum storage rate of 100 samples per second can be set for both channels allowing for the capture of short duration process signal anomalies.
The DC1250 is an economical dual input process recorder. CompactFlash cards up to 2 GB in size can be used allowing many data points to be stored over long periods of time. The DC1250 can be used in configuration with many of Monarch's speed measurement sensors; power for sensors is provided from the recorder's rear terminals.
With intuitive operation, flexible input configuration, and versatile standard features, the DataChart 1250 is a powerful, compact recorder.
A Clear View
The DC1250 has a highly reflective twisted nematic LCD with a bright white LED backlight. The graphic user interface can be configured to display real-time data in a digital or trend format. Configuring the DC1250 is an intuitive process which uses an easy to follow menu system.
The DC1250 is supplied with a universal wall transformer power supply that can operate from 100 to 240Vac 50/60Hz. Interchangeable plugs for UK, EUR, North American, and AUS are also supplied.
Isolated input power of 12-24Vdc is also available for use with instrument power supplies or external batteries. The DC1250’s real-time clock and internal RAM have a battery back-up to preserve data in the event of a power loss.
If losing data during a power outage is a concern, the user can add the rechargeable battery pack option. With the battery pack option installed, the DC1250 automatically keeps the rechargeable NiMH batteries charged to capacity. In the event of a power loss, the DC1250 automatically switches over to internal battery power. All functions continue to operate as normal for up to 6 hours! This option is also great for using the DC1250 in areas where no AC or DC power is available.
A rear accessible RJ45 Ethernet port is available. With this option, the DC1250 can be connected to any Standard 10/100BaseT Network. Access and transfer data stored on the compact flash card. View real-time trended data and remotely control and configure recorder with Navigator software. The built-in web-server allows real-time data viewing with only an internet browser.
A front-accessible USB port is available. Access and transfer data stored on the compact flash card. View real-time trended data and remotely control and configure recorder with Navigator software. A USB port cannot be ordered with an Ethernet option.
DataChart® Navigator Software makes reviewing, printing, and exporting data easier than ever. Simply start the program, double-click the data file, and Navigator does the rest. Your data file is displayed in one graphic window complete with the scales as programmed in the DC1250 as well as Date and time stamps. You can expand, compress, or use the box zoom to display specific areas of data as needed. The print preview feature allows review prior to printing.
Exporting data is as simple as clicking the Excel™ Icon in the Data table export window. Navigator automatically converts the historic data, starts up Excel™, and loads your data into an organized spreadsheet.
The DC1250 can be used in conjunction with many of Monarch’s speed measurement sensors. Power for sensors is provided from the DC1250 rear terminals. Measure, display, and record RPM range from 0 - 600,000. Choose the sensor best suited for your application or take your existing signal (0 - 5V TTL) directly into the DC1250.
