...from the simplest Signal Conditioning...

...to the most exacting Dynamic Test Applications. (Click on image for a better view)

Precision...

• SPS6000's programmable low-pass filters minimize the effects of aliasing and electrical noise, so you measure the exact signal your transducer has generated.
  
  
• Analog function modules allow accurate event- and time-coordinated measurements with immediate analysis and control action.
  

Flexibility...

• With its modular and easily expandable architecture, SPS6000 adapts readily as your requirements change and grow.
  
  
• SPS6000 provides programmable signal pathing and hardware assignments via its Configuration Software, so that a single test stand can be used for multiple tests, with minimum changeover time.
  

Reliability...

• SPS6000 employs Daytronic Conditioner Cards--a signal conditioning technology whose accuracy, stability, and reliability have been field-proven over the last 15 years.
  
  
• Daytronic has over 40 years' experience in the design and manufacture of signal processing instrumentation for measurement and analysis.
  

• An extensive family of multichannel Conditioner Cards optimized for particular transducer types and ranges and capable of monitoring "noisy" measurement signals with input bandwidth up to 10kHz (typical accuracy is 0.02% of full scale, after calibration, over the full temperature range).
  
  
• User-selected analog function modules for real-time capture and evaluation of specific instantaneous signal characteristics prior to A/D conversion.
  
  
• Software-scaleable +/- 10-V analog outputs for connection to industry standard data acquisition cards or appropriate PLC inputs.
  
  
  

• Sum/Difference Module The Model SPS6701 calculates on a real-time basis the algebraic sum of multiple independent analog measurement signals prior to A/D processing. This Module accepts six analog inputs, four additive and two subtractive. It generates two analog outputs: (1) a "Sum Output," which continuously represents the algebraic summation of all active inputs, and (2) a "Minus Sum Output," which is simply the present value of the "Sum Output" with opposite polarity.
  
  
• Peak and Track/Hold Module The Model SPS6702 is an extremely versatile application tool. It accepts a singl eanalog input signal and produces two analog outputs.
  • In Track and Hold mode, when the "Track" input is "true" and the "Hold" input is "false," the value of the "Output" signal will be continuously identical to that of the input signal. As the input value varies, no signal peaks will be captured and no value will be "held."
    
    
  • In Peak Capture and Hold mode, when both the "Track" input and the "Hold" input are "false," the value of the "Output" signal will represent the greatest maximum or minimu value experienced by the input signal since peak capture operation last began. Any captured peak can be "held" by subsequentialy causing the "Hold" input to go "True."
    
    
  • In Sample and Hold mode, instantaneous "samples" of the signal input can be captured and held by means of the "Acquire" and "Dis(able) Acquire" inputs. The sampling of a given parameter can be triggered, for example, by the status of another variable which is being continuously evaluated by a Comparator Module (Model SPS6704)- and even then, it can be made to occur only when permitted by a precisley defined "gate."
    
    
• Auto Zero Module The Model SPS6703 allows quick, automatic establishment of an arbitrary zero reference point for ensuing measurements- as required, for example, in comparator gaging operations with a "Zero Master," automatic taring of container weights in batch weighing operations, and the adjustment of zero baseline for graphic recording. It can also provide indefinite digital hold of an instantaneous signal value, without the decay inherent in analog capacitor storage.
  
  
• Comparator Module The Model SPS6704's function is to issue logic output to one or more other modules on the same ASP card (or to one or more external logic devices), based on the comparison of input signal values to user-entered setpoint values or to the values of other input signals. A Comparator output can serve not only as a "GO-NO GO" control command to an external process actuator, but also as a real-time trigger for a "sample and hold," "tare capture," or other internal SPS6000 analog processing function.
  
  

• Compact, rugged chassis of extruded metal (4.0" H x 9.65" W x 13.5" D, regardless of output capacity); splash-resistant front panel; clamp slides allow mounting in user's precut panel.
  
  
• Continuous power range from 90 to 240 V-AC (47-63 Hz), 55 W maximum.
  
  
• ESD protection of all inputs and outputs.
  
  
• Operating temperature range: +5 °C to +50 °C (+41 °F to +122 °F);
  operating humidity range: 5 to 95%, noncondensing.
  
  
• ANALOG INPUTS: Up to 32 per mainframe; advanced conditioner cards offer PROGRAMMABLE ANALOG FILTERING for quieting excessively noisy signals and eliminating A/D aliasing problems.
  
  
  • Exceptional STABILITY and ACCURACY result from...
    
    
    • shielded front-end environment that won't limit the accuracy of sensitive input signals or the reliability of associated control functions.
      
      
    • premium low-drift components.
      
      
    • remotely sensed excitation, allowing long cable runs.
      
      
    • separate amplifier for each input channel, with gain / noise / drift characteristics optimized for a specific input type.
      
      
    • powerful low-pass active filtering on an individual-channel basis.
      
      
    • precise control of internal reference voltages.
      
      
    • precise built-in calibration and excellent interchangeability of conditioner cards.
      
      
• ANALOG OUTPUTS: From one or two Analog Signal Processor (ASP) Cards--up to 8 or 16 per card.
  
  
  • Accuracy: 0.02% of full scale, typical, following calibration.
    
    
  • Voltage: ± 10 V-DC will drive 500 ohm load.
    
    
  • Bandwidth: up to 10 kHz, set by conditioner card.
    
    
• ANALOG FUNCTION MODULES: Up to 8 per ASP card; presently include:
  
  
  • computation of SUM and DIFFERENCE (4 additive inputs; 2 subractive inputs).
    
    
  • TRACK and HOLD; ± PEAK CAPTURE and HOLD; SAMPLE and HOLD.
    
    
  • signal AUTO-ZERO, with digital hold capability.
    
    
  • continuous COMPARATOR FUNCTIONS ("Hi-Lo", "Dual", and "Window" modes).
    
    
• LOGIC INPUTS AND OUTPUTS: Each ASP card can have up to 8 inputs for direct control of assigned processing functions and up to 8 outputs for external annunciation and control.
  
  
  • General: ± 5 V Reference Supply provided; maximum current is 50 mA, total; external reference supply may be used; allowable Vcc range is +5 to +24 VDC.
    
    
  • Logic Inputs: High-impedance device with internal 100K ohm pull-up to Vcc ("Logic 1"); may be driven by TTL, LSTTL, CMOS (+5 V), or through dry contacts to Common.
    
    
  • Logic Outputs: Open-collector current sink with internal 100K ohm pull-up to Vcc; maximum sink current is 50 mA per output.
    
    
• ON-BOARD DIAGNOSTICS: Relay contacts are provided on the rear of the unit to report system health status--including internal voltage supplies and software verification--to the host device or other external device for alarm monitoring and annuciation.
  
  
• STANDARD FRONT-PANEL LED DISPLAY WITH OPERATOR KEYPAD: permits any active data channel to be viewed either as a finished engineering-unit answer or as a pure voltage. The operator can perform most calibration functions directly by means of front-panel push buttons--provided that the level of security presently set for the system allows such operations.
