Description
The DT9857E is a high accuracy dynamic signal acquisition module for noise, vibration, and acoustic measurements. Eight or sixteen, 24-bit, IEPE (ICP®) sensor inputs are synchronized with a tachometer input, two measurement counters, and a general purpose counter/timer to provide data streams that are matched in time, for field or laboratory use. An 8-bit digital output port is available for control. This rugged, compact module, available either as an OEM board or steel-encased module, connects via USB making them ideal for many measurement applications.
Features
- Simultaneous IEPE analog inputs, waveform stimulus analog outputs, tachometer synchronous with input data stream, advanced pre and post triggering, 16 DIO (8 in/8 out), synchronous counter/timers, and Sync Bus for up to 256 A/D channels and 32 D/A channels.
-
All inputs and outputs can be synchronized for measurement data coherence...
- Supports the ability to return the value of the digital input port, tachometer, measure counters, and general-purpose counter in the analog input data stream, all synchronous with analog input data stream…providing correlation of tachometer or any digital input with analog signals.
- Eight (DT9857E-08) or sixteen (DT9857E-16) Simultaneous, IEPE inputs, 4mA at 24V compliance, all inputs use 24-bit Delta-Sigma A/D converters for high resolution measurement to 105.4kHz, AC or DC coupling.
- Start trigger (software, threshold, external, or Sync Bus) for acquiring post-trigger samples; reference trigger for acquiring pre/post trigger samples.
- Analog threshold trigger on any of the analog input channels to program the threshold value from –10V to +10V.
- SyncBus connector for synchronizing acquisition and waveform stimulus on up to 16 DT9857E modules
- External 4.75V to 28V Power Supply
