DataChart® DC1250 2 Channel Paperless Recorder

A maximum sample storage rate of 100 samples per second can be set for both channels allowing for capture of short duration process signals anomalies. CompactFlash™ cards up to 2 Gigabyte size can be used allowing many data points to be stored over long periods of time.

With intuitive operation, flexible input configuration and large memory capability, the DataChart 1250 is a powerful, compact digital recorder.


Ethernet Communication
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-browser allows real time data viewing with only an internet browser.

A Clear View
The DC1250 has a highly reflective twisted nematic LCD display with a bright white LED backlight. The graphic user interface can be configured to display real time data in digital or trend format. Configuring the 1250 is an intuitive process which uses an easy to follow menu system.

Versatile Power
The DC1250 is supplied with a universal wall transformer power supply (North American plug) that can operate from 100 to 240Vac 50/60Hz. An optional transformer with an interchangeable plug set is available.

An 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 8 hours! This option is also great for using the DC1250 in areas where no AC or DC power is available.

USB Communication
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. USB port cannot be ordered with Ethernet option.

Nema 4x Enclosure Option

The NEMA4X kit consists of a heavy duty molded plastic NEMA4X enclosure with a lockable hinged door and the SPC1250 splash proof cover. The door of the enclosure is die cut to accept the DataChart1250. When using this kit, the DC1250 can be mounted outdoors or in harsh wet environments. The kit also includes stainless steel mounting feet for wall mounting. The enclosure can be easily drilled to accept conduit or watertight gland fittings for input signal and power wires.

Measure RPM

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 ranges from 0 - 600,000. Choose the sensor best suited for your application or take your existing signal (0 - 5V TTL) directly into the 1250.

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.
