  • Page 128 This appendix describes additional considerations to keep in mind when designing your own screw terminal panel for use with a DT3010 Series board.

  • Page 129: Analog Inputs

    Using Your Own Screw Terminal Panel Analog Inputs Typical data acquisition 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 130: 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 131: Differential Inputs

    Using Your Own Screw Terminal Panel Differential Inputs Differential inputs offer the maximum noise rejection at the expense of half your total channel count. For the best results, shielded twisted pairs are a must. The shield must connect at one end so that ground currents do not travel over the shield.

  • Page 132: Analog Outputs

    12 to 16 bits (even though the accuracy may be less). On all Data Translation boards, we ensure that the analog outputs do not break into a high frequency oscillation with high capacitance loads that may be experienced with long cables. Typically, the analog outputs drive 1,000 pF without degradation and bandwidth-limit with higher capacitive loads.

  • Page 133: 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 134: 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.
