The BK Precision DAS240-BAT measures parameters commonly found in process applications including voltage, temperature, current, resistance, frequency and pulse. It includes 20 universal analog channels with convenient screw input terminals that can be expanded up to 200 channels. This recorder was developed by B&K Precision’s subsidiary Sefram in France, which specializes in the design and manufacture of recorders, field strength meters and other test and measurement instruments

Measurement results can be viewed graphically and numerically on a 10 inch color touchscreen and saved to internal memory or an external USB memory stick. Icon-driven menus make the instrument easy to navigate. The free DasLab Windows PC software allows users to remotely control and configure the recorder, transfer logging results and configuration files, and view live data in graphical or numerical format on the PC.

The tools you need

Expandable up to 200 analog channels

The DAS240-BAT provides a flexible and scalable analog channel concept. Each unit is supplied with one 20-channel analog module and 20 screw input terminal blocks, enabling voltage and temperature measurements with thermocouples or Pt100/Pt1000 sensors. By stacking and daisy-chaining additional modules, the total number of channels can be incremented by 20 to a maximum of 200 channels (10 modules).

Adding an optional 50 Ω (0.01%) shunt input terminal block to any 20 channel module provides current measurement capabilities, ideal for 4-20 mA measuring and monitoring applications.

Virtual Network Computing (VNC) capability

The recorder’s built-in VNC capability, based on the Remote Frame Buffer protocol (RFB), provides a graphical desktop sharing system to remotely control the instrument from another computer. VNC is platform independent and provides a means to control all functions of the instrument through a graphical interface replicating the instrument’s front panel, using a mouse and keyboard.

DasLab Software

DasLab is a license-free Windows compatible software that can be downloaded from www.bkprecision.com. The software controls the recorder through the LAN interface and provides the following features:

• Channel and trigger configuration
• Display live measurement results in graphical or numerical format
• File management, file upload and download of data recordings, screen captures and configuration files
