Item Specifications
Type Plug-in input unit
Number of slots 8
Maximum number of input
channels
16 channels per slot, 128 channels per unit (when a 16-CH voltage input module is installed in each
slot)
Maximum record length The maximum length when all channels are being used depends on the number of channels in
each module.
The maximum values when the entire memory is used are listed below.
Standard 250 Mpoint when 1 channel is being used. 10 Mpoint per channel when 16 channels
are being used.
/M1 option 1 Gpoint when 1 channel is being used. 50 Mpoint per channel when 16 channels
are being used.
/M2 option 2 Gpoint when 1 channel is being used. 100 Mpoint per channel when 16 channels
are being used.
Real Time Math channels
(option)
The DL850E/DL850EV is equipped with 16 dedicated channels for performing computations. This
enables you to perform the following computations in real time on 16 analog input channels or
16 realtime math output channels: digital filter, basic arithmetic, basic arithmetic with coefficients,
differentiation and integration, angle of rotation, logic signal/analog waveform conversion, quartic
polynomial, rms value, power, integrated power, common logarithm, square root, cosine, sine, arc
tangent, electrical angle, knocking filter, coefficient multiplied by addition or subtraction of sources,
frequency, period, edge count, resolver, IIR filter, demodulation of the pulse width modulated signal,
reactive power, CAN ID detectionand, torque, angle difference, and 3 phase resolver. (For detailed
specifications of Real Time Math channel’s math features, see section 6.5, Features.)
Real Time Math features are as follows:
• Even when the display is in roll mode, you can view the math results.
• There are no restrictions on the record length. You can specify a record length that is the same as
a normal input channel.
• Math results can be used to trigger the DL850E/DL850EV.
• Because both acquisition and computations can be performed at the same time, you can make
the waveform update period shorter than it is with normal math operations.
