The Spider-81 is the flagship model of Crystal Instruments vibration
controllers. This 4th generation hardware is highly modular,
distributed and scalable. Each Spider-81 has 8 analog input and
4 analog output channels. Eight digital I/O pairs are provided for
custom applications. A bright front panel LCD displays the system
status and test information. Users can instantly view real-time
status information such as control RMS or sweeping frequency
on the LCD panel.
The Spider-81 not only uses Ethernet for data communication,
it goes further by employing IEEE 1588v2 time-synchronized
Ethernet connectivity. This technology allows (up to 100 meters in
distance) remote input modules to be connected solely by Ethernet
(with no dedicated “sync” cable required), while still provides
sampling and triggering synchronization within an accuracy of 50
ns. The Spider-HUB industrial Ethernet switch can expand the
Spider-81 controller up to 512 input channels. All input channels
across the system are amplitude matched within 0.1 dB and phase
matched within 1° over a 20 kHz bandwidth.
All Spider front-ends contain a 4 GB flash memory for the storage
of data and test processing instructions. If longer recording is
required, the Spider-NAS (Network Attached Storage) provides at
least 250 GB of solid-state disk (SSD) storage in a removable SATA
cartridge. One Spider-NAS records streamed time waveforms for
up to eight Spider front-ends at the same speed of 102.4 kHz per
channel.
"Spider-81 Front-end: Four 24 bit IEPE/Voltage/Charge inputs enabled, Two 24 bit outputs, BNC connectors, LCD display, Ethernet connection, and Black Box engine. Can be expanded to 64 channels with other Spider- 81 or Spider-80X front-ends.
