labV12 (Code 3723)
12-channel Line/ICP input module
Variants: labV12-V1 (Code 3723-V1) labV12-V2 (Code 3723-V2)
Overview
labV12 is a 12-channel Line/ICP
module equipped with a high-pass
filter for each channel, switchable
channel by channel. The compact
and rugged module features an
excellent phase accuracy of the 24-bit
data, and a signal-to-noise-ratio of
107 dB(A).
Features
yy Input module with 12 Line/ICP
chan­nels
Variants

system)
yy MMF III.0 (BrakeOBSERVER)

Connections for sensors
yy Line/ICP sensors

sensors (via SCU-V2)
Functions
yy 24 bit data with high phase
accuracy

yy 107 dB(A), signal-to-noise-ratio
(range: 1 V)
yy Sampling frequencies: 2, 3, 6, 12,
24, 48, 96 kHz
-- HEADlink 1 ↔ controller: 12 channels up to 24 kHz, 6 channels up to 48 kHz, 3 channels up to 96 kHz

Subject to change
-- Dual-link: HEADlink 1 and
HEADlink 2 ↔ controller: 12 channels up to 48 kHz, 6 channels up to 96 kHz
yy Input impedance: 30.3 kΩ (labV12), 300 kΩ (labV12-V1), 1 MΩ (labV12-V2)
yy Low power consumption (7.5 W)
yy Electrical isolation of the labV12
inputs to the inputs of other
­HEADlab modules and the PC
interface
Filters
yy Analog high-pass filters: 2.5 Hz
(labV12-V1: 0.35 Hz; labV12-V2:
0.4 Hz) in AC mode, 22 Hz,
switchable channel by channel
Handling
yy Silent (no fan), rugged design
yy Integrated locking mechanism (the modules can easily be mated
to a system)
At the front of the modules the interfaces are summarized in two D-Sub
sockets to connect the sensors via
breakout cables.
Connecting a labV12 mod­ule with a
controller via both HEADlink interfaces simultaneously (dual-link),
the available sampling rate will be
doubled.
The labV12 is supplemented by the
variants labV12-V1 and labV12-V2
which have a higher input impedance
and a lower AC cut-off frequency. It is
possible to convert a labV12 mod­
ule into the variants labV12-V1 or
labV12-V2 ex factory.
Together with a controller and a power supply module up to 10 labV12
can be assembled forming a system
with 120 channels, at a sampling frequency of up to 24 kHz. Via dual-link
the use of 5 labV12 with 60 channels
at 48 kHz is allowed.
Depending on the processing power
of the PC and the network utilization,
larger systems with several controllers,
power supply modules and labV12
modules can record up to 600 channels at 24 kHz simultaneously.
