Sensor-CASSY, 3 HU

Interface device for recording measurement data

• For connection to the USB-port of a computer
• 3-fold electrical isolation (4-mm-inputs A and B, relay R)
• Measurement possible parallel at 4-mm-inputs and sensor box connector sites (4 channels)
• Up to 8 analog inputs per Sensor-CASSY retrofittable using sensor boxes
• Automatic sensor box detection (plug and play) by CASSY Lab 2 (524 220)
• Microprocessor-controlled with CASSY operating system (easily updatable via software for function enhancements)
• Developer Information and LabVIEW^TM driver available through our internet homepage
• Assembled in a 3 HU module to be integrated into a power supply channel. The USB socket is located at the front side.

Technical data

• 5 Analog inputs
  2 Analog voltage inputs A and B on 4-mm safety sockets (electrically isolated)
  Resolution: 12 bits
  Measuring ranges: ± 0.1/0.3/1/3/10/30/100/250 V
  Measurement error: ± 1 % plus 0.5 % of range end value
  Input resistance: 1 MΩ
  Scanning rate: up to 1 MHz per input
  Amount of measured values: nearly unlimited (dependent on PC) up to 10,000 values/s, at higher measuring rate max. 200,000 values
  Pre trigger: up to 50,000 values per input
  1 Analog current input A on 4-mm safety sockets (alternatively to voltage input A)
  Measuring ranges: ± 0.03/0.1/0.3/1/3 A
  Measurement error: voltage error plus 1 %
  Input resistance: < 0.5 Ω
  Scanning rate: up to 1 MHz per input
  See voltage inputs for further data
  2 Analog inputs at sensor box connector sites A and B
  (All CASSY sensor boxes and sensors can be connected)
  Measuring ranges: ± 0.003/0.01/0.03/0.1/0.3/1 V
  Input resistance: 10 kΩ
  Scanning rate: up to 500 kHz per input
  See voltage inputs for further data
  The technical data will change depending on a connected sensor box. In this case CASSY Lab 2 automatically detects the possible measurement quantities and ranges when a sensor box is attached.
• 4 Timer inputs with 32-bit counters at sensor box sites A and B (e.g. for BMW box, GM box or timer box)
  Counting frequency: max. 1 MHz
  Time resolution: 20 ns
• 1 Changeover relay (switching indication via LED)
  Range: max. 250 V / 2 A
• 1 Analog output (LED switching state indicator, e.g. for holding magnet or supplying experiment)
  Variable voltage range: max. 16 V / 200 mA
  (load ≥ 80 Ω)
• 12 Digital inputs (TTL) on sensor box sites A and B (at present only used for automatic sensor box detection)
• 6 Digital outputs (TTL) on sensor box sites A and B (at present only used for automatic switching of a sensor box measuring range)
• 1 USB-port for connection to a computer
