Data Sheet
Portable Multi-Channel Recorder
Model DAS240-BAT
The 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
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.
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 measure-
ments 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).
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.
