6.12 6-ch. Dyn-X Input Modules Types 3041, 3041-B
This module comes in two versions: Type 3041
with LEMO and BNT/BNC connectors on the in-
put channels and Type 3041-B with a 37-pin D-
sub connector. For input of signals in one range to
10 V
peak
(dynamic range 160 dB) over the frequency
range to 25.6 kHz.
6.12.1 Common Features
The modules can provide polarization voltage to
all channels simultaneously and support
IEEE 1451.4 capable transducers with TEDS. Input
may be grounded or floating, controlled by PULSE
software.
LEDs
Measuring: Indicates a measurement in progress
or the downloading of software to the module.
Input 1 to 6: For each channel, an LED indicates
the status of the channel (activated: green; over-
load: red). See section 7.8. On Type 3041, the
LED surrounds the connector.
6.12.2 Type 3041
Note: The LEMO and BNC connectors of each channel are connected in parallel. You
should therefore only connect one transducer to each pair of connectors at any one time.
Input 1: BNT connector (see Fig.7.3 on page 89) for direct connection of a voltage signal
or for connection of CCLD transducers and 7-pin LEMO connector (see Fig.7.6 on page 90)
for use with Brüel & Kjær microphones. The BNT connector also provides power for a tacho
probe.
Inputs 2 to 6: BNC connectors (see Fig.7.4 on page 89) for direct connection of a voltage
signal or for connection of a CCLD transducer, for example, DeltaTron
®
accelerometers or
microphone preamplifiers, and 7-pin LEMO connectors (see Fig.7.6 on page 90) for use
with Brüel & Kjær microphones.
6.12.3 Type 3041-B
37-pin D-sub connector for inputs 1 to 6. See Fig.7.9 on page 93.
The module provides a supply for CCLD transducers, for example, DeltaTron
®
accelerometers,
and for microphone preamplifiers.
