Refer to Appendix B of the DT300 Series User’s Manual on the OMNI CD-ROM (see page 11 for information on viewing this manual) for connector and cable specifications.

  • Page 89: Analog Inputs

    Using Your Own Screw Terminal Panel Analog Inputs DT300 Series boards have three different types of analog input configurations that you can use: • Single-ended, • Pseudo-differential, and • Differential. Single-Ended Inputs With single-ended inputs, you have the maximum number of inputs but have the worst-case noise immunity without external signal conditioning.

  • Page 90: Pseudo-Differential Inputs

    Appendix A Pseudo-Differential Inputs Pseudo-differential inputs allow one common-mode voltage for all single-ended inputs. With this type of connection, the low side of the instrumentation amplifier is used to sense an external common-mode voltage. For example, if you have a signal-conditioning rack, the AMP LOW signal connects to the analog common of the external rack.
  • Page 91 Using Your Own Screw Terminal Panel With a very small bias current multiplied by this high input impedance, the voltage produced is out of the common-mode input range of the instrumentation amplifier. An external resistor must be provided to return this bias current to the analog common of the data acquisition board.

  • Page 92: Analog Outputs

    Appendix A Analog Outputs The analog output channels on DT300 Series boards have a resolution of 12 or 16 bits (even though the accuracy may be less). Data Translation ensures that the analog outputs do not break into a high frequency oscillation with high capacitance loads that may be experienced with long cables.

  • Page 93: Digital Inputs And Counter/Timer Inputs

    Using Your Own Screw Terminal Panel Digital Inputs and Counter/Timer Inputs TTL-type inputs must have current limiting so that circuitry is not damaged when power is removed. On all Data Translation PCI boards, current limiting is used to prevent damage in this fault condition.

  • Page 94: Digital Outputs

    Appendix A Digital Outputs If you are using the high drive capability of any of the PCI boards, ensure that the load is returned to the digital ground provided in the connector next to the outputs. If just eight of the digital outputs are switching 16 mA per output, then 128 mA of current flows.
