Dragonfly8-1429-BNC

The Dragonfly8-1429-BNC provides 8 channels of Voltage, IEPE and optionally Charge conditioning hosted in our modular Dragonfly Chassis. The unit is targeted at high-quality vibration and acoustic applications in moderate / challenging environments.

This model is provided with IP65 rated BNC Front Panel connectors, alternate model with 2-pin LEMO 1B (-LEMO2) or 8-pin LEMO 1B connectors (-LEMO8) are available if required.

As with all other HGL units, it includes our standard interface connections presented on the Hardware Overview page, including for the first time in this form factor, integrated Calibration (Internal and External), IRIG A/B Synchronisation and Buffered Analogue Outputs. This means that the Dragonfly8-1429-BNC can connect with and interoperate with any other HGL Modular Front-Ends.

The Dragonfly8-1429-BNC is presented in a V5 Dragonfly Standard (140 x 150 x 75mm) Milled Aluminium Hard Anodised Chassis, ideal for harsh Environmental locations including on Vehicle applications. Up to three Dragonfly8 modules can be mounted on an HGL Rack mount shelf or units can be connected together via the site mounted T-slots and H bars.

The Dragonfly8-1429-BNC is fully supported fully by HGL’s Data Acquisition Software as well as our Labview, Windows DLL and Network API models.

Features

8 Channels

8 identical channels

Built-in Conditioning

Voltage
IEPE (4mA excitation, TEDS support)
Optional Charge (SE / DF and High Temperature SE/DF)
AC/DC coupling
0.1x to 200x gains in 1,2,5 steps

Multiple Synchronizing Types

Natively supports IRIG A/B, IEEE-1588 (PTPv2) and HGL LVDS for precise synchronisation to < 50nS resolution across entire systems. GPS is optionally available.

Simultaneous Sampling

Supports individual Sigma-Delta ADCs per channel synchronized to better than 10ns across all channels in the unit.

Flexible Sample Rates

Supports sample rates from 1kHz to 256kHz (in 1Hz steps) to be chosen for each block of 8 channels. Due to careful design the majority of these sample rates are precise.

140dB Dynamic Range

Utilises instrumentation grade Sigma-Delta 24-bit ADCs for input signals with up to 140dB Dynamic Range (-120dB SFDR) on all channels

Flexible Power

Supports DC power from 9 to 36V (automotive ranges) and PoE to 802.3bt (100W) standard.
AC power supplies are supported through a range of external adaptors

Environmentally Sealed

Designed to be used in environmentally challenging environments, no exterior openings and are sealed to IP65 (min) standard against fluids including jet fuels, lubricants etc.

Rugged

Intended for use in harsh vibration environments in test cells close to test vehicles and even on test vehicles.

Conduction Cooled

Conduction cooled through innovative internal design and materials.
Accurate Operation from -55 to +80C.

Flexible and Scalable

Fully interoperable with other DAQ modules.
Connection of multiple units is simple and quick and allows complex systems up to and above 1000 channels to be realised easily
