Features

The DAQ for PCMCIA i250 card is a type II PCMCIA I/O card for notebooks and other computers containing a PCMCIA slot.

It offers 16 single-ended or 8 differential inputs. All input channels are multiplexed on a 12 bit A/D converter. The maximum conversion rate is 250kHz. In addition, there are 8 digital, TTL compatible, inputs and outputs.

Optionally, the card can be equipped with 2 asynchronous 12 bit D/A converters in turn for 4 digital I/O ports. The D/A converters are suitable for voltage output and for low speed closed loop applications.

The card can be operated using Microsoft® Windows® 95/98/ME, Windows NT® and Windows® 2000 operating systems. For instant use, FreeVIEW provides a graphical environment.

Applications

The DAQ for PCMCIA i250 can be used in many environments for automation of machines, process monitoring and control, instrumentation and electronic test functions. Low-power sleep mode makes the card a practical choice for developing portable data acquisition systems.

Analog Input

All analog input channels have an input impedance of 10 MOhm with an input capacity of 20pF. All inputs are provided with over voltage protection up to +/-35V.

The conversion rate ranges from 0.5Hz (305Hz with trigger condition) to 250kHz and can be set by software. To assure a high data rate, the i250-16 has 32 Kbytes FIFO buffer (16384 samples) that prevents digitalized measured data from being lost. Triggering and sampling into the FIFO buffer is controlled by cards hardware entirely.

The i250-16 can acquire data in the sampling modes:

  • Individual sampling of various channels.
  • Alternate sampling of all or a subset of channels.
  • As above, but with triggering (signal edge or threshold value). Pretrigger is adjustable. Recording depth is 16384 values.
  • Sampling at intervals set by controlling software.

Trigger

The start of the data acquisition is triggered by level or signal edge. It can be triggered when there is a fall below or a rise above a certain level. Also, the trigger can be set by recognition of a falling or rising signal edge.

Since the trigger is hardware controlled, no time delay arises between a triggering condition and the start of recording. This eliminates the loss of data during the trigger state.

Digital I/O

8 digital I/O lines provide TTL compatible level, the maximum current is 4mA.
