The Simcenter SCADAS Mobile and SCADAS Recorder (formerly called LMS SCADAS) are part of a family of modular data acquisition devices used for capturing dynamic signals at a rate up to 204.8 kHz sampling rate per data channel.
The systems can read a variety of transducers, including strain gauges, accelerometers, microphones, thermocouples, speed encoders, GPS, digital CAN-bus, and more…
The Simcenter SCADAS Mobile and Recorder are modular, and consist of a combination of:
Frame: Housing unit which contains all cards, controllers, and power supply. Comes in variety of sizes.
Connector Module: Option used to combine or link multiple SCADAS frames together.
Power Supply: Contains battery for autonomous operation, also accepts external AC or DC power.
Mobile OR Recorder Controller Card:
The controller card is referred to as a XSI or Syscon card. It is included with all SCADAS frames with the exception of slave frames.
Mobile: Ethernet interface for linking to control PC with Test.Lab software, two source outputs, two tachometer/encoder inputs.
Recorder: Same as Mobile with addition of Compact Flash for un-attended data acquisition, WiFi or Bluetooth for remote control, GPS/IRIG-B, and CAN-bus inputs.
Data Acquisition cards: Typically 8 or 24 input channels per card; see variety of card options in table below.
SCADAS is an acronym for Signal Conditioning and Data Acquisition System.

DC Power – 10.8 to 42 Volts with inverse voltage protection.
Annual hardware calibration fully compliant with ISO9001-2015 standards.
Inputs:
Accommodates 8 to 216 channels (multiples of 8 channels) in a single frame, depending on measurement cards used.
Up to 204.8 kHz sampling rate per channel and throughput up to 14 MSamples/s with a 150-dB dynamic range, with 24-bit delta-sigma ADC technology.
Includes CAN Bus, IRIG-B, dual tachometer and signal generator support, with optional GPS.
Interfaces:
High-speed Ethernet host interface.
Optional Recorder model can work autonomously as a blind recorder with Compact Flash, tablet-operated recorder, or frontend system for laptop or PC (GPS standard with recorder model only)
Fiber-optic connection module for expandability with fully synchronized data saved to one file
Size and Weight:
Ranges from 5.5 lbs (2.5 kg) to 23 lbs (10.5 kg) based on frame size and number of cards
2. Frames:
Each SCADAS Mobile or SCADAS Recorder can be configured to customer-specific testing preferences:
SCADAS frames include either a SCADAS Mobile or SCADAS Recorder controller card, unless ordered as a slave frame. Any frame size can be ordered either as a Mobile or as a Recorder.
Empty slots are allowed. Expansion slots do not need to immediately be filled with a data acquisition card, since they can be installed later. Additions will be automatically recognized with no additional software configuration, etc.
For Vibration Control applications, the SCADAS can be ordered with a modified source. The modified source has shutdown capability to avoid unintended test article and shaker system damage.

Below is a list of cards available for the SCADAS frames. Some key points:
Cards need to be placed in either an existing SCADAS frame or new SCADAS frame to function.
Cards typically consist of either 8 or 24 input channels.
Base codes in table below (e.g., VB8). Cards when ordered will have extensions, for example "E" for Enhanced, or "-II" or "-III" for 2nd or 3rd generation (e.g., VB8-II).
Cards often have cable adaptors included. For example, LEMO to BNC adaptors, etc. Check with your sales representative to understand which cables are included when purchasing a specific card.
Some cards can have options for connector type, for example D-Shell connector instead of individual inputs.
