FeaturesThe DAQ pci250 is a high performance data acquisition card for desktop computers. 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. |

|
ApplicationsThe DAQ pci250 can be used in many environments for automation of machines, process monitoring and control, instrumentation and electronic test functions. |

Analog InputAll analog input channels have an input impedance of 10 MOhm with an input capacity of 20pF. All inputs are provided with overvoltage protection up to +/-35V.The conversion rate ranges from 0.5Hz (305Hz with trigger condition) to 250kHz and can be set by software. Triggering and sampling is controlled by card's hardware entirely. The DAQ pci250 can acquire data in the sampling modes:
TriggerThe 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/O8 digital I/O lines provide TTL compatible level, the maximum current is 4mA.ConnectorA standard 37 pole D-SUB connector (jack type) is used for accessing the analogue inputs and digital inputs and outputs.In addition, multiple supply voltages (5V/200mA, -15V/10mA, +15V/10mA) and an external trigger input are available. |
