© National Instruments Corporation A-1 SCXI-1163 User ManualAppendix ASpecificationsThis appendix lists the specifications for the SCXI-1163. These are typical at 25° C and 50%humidity unless otherwise stated. The operating temperature range is 0° to 50° C.Digital OutputsPower requirements (per port)Supply voltage +5 V ± 0.5 V+7 V absolute maximumSupply current 60 mA/port typical80 mA/port maximumOutputs Open-collector digital outputs with 4.7 kΩ pullupsLogic low output voltage(Iout = 12 mA) 0.4 V typical0.6 V maximumOutput current (outputs low) 15 mA maximumIsolation Port to port and port to groundBreakdown 1,900 Vrms maximumWorking 450 Vrms maximumMaximum speedPropagation delay (parallel mode) 100 nsecRise time 1 (into 100 pF) 1 μsecSerial data rateMeasured using NI-DAQ softwareon a 486-50 computer 700 writes/secMeasured using NI-DAQ softwareon a 386-33 computer 350 writes/secCommon-mode rejection 500 V/μsec typical100 V/μsec minimumPhysicalDimensions 1.2 by 6.8 by 8.0 in.Connectors 50-pin male ribbon-cable rear connector48-pin DIN C male front connector(48-screw terminal adapter available)1 You can add pullup resistors to obtain faster rise times. Be aware, however, that adding pullup resistorsaccordingly increases the current that the output uses.
