Model SPS6216 Sixteen Channel Analog Signal Processor Card

The SPS6000’s Analog Signal Processor card or card set is the heart of every SPS6000 system. Every SPS6000 mainframe has standard slots for up to two ASP cards. The principal functions of an ASP card are:

  • to perform real-time “mx + b” scaling and calibration of analog input signals received from system conditioner cards, based on transducer and output values entered by the user through the Configurator Software (following this initial “calculated” calibration, additional on-line “zero and span” calibration can be performed, if necessary, to improve measurement accuracy)
  • to apply specific processing functions to these signals on a real-time basis, if required, via user-selected FUNCTION MODULES installed on that card
  • based on these scaling, calibrating, and processing functions, to generate high-level analog outputs for delivery to an external PC, PLC, or other data acquisition system supplying its own A/D conversion, and also to generate logic outputs for control and annunciation

The Model SPS6208 Analog Signal Processor Card can produce up to 8 independent analog outputs; the Model SPS6216, up to 16. Each analog output derives either directly from a signal conditioner or from the output of a particular function module.

In addition to 8 or 16 analog outputs, each ASP card has 8 logic input terminals and 8 logic output terminals. The specific function of each logic line will be determined by the user during system configuration. In general, ASP logic inputs are accepted directly from external dry contacts (switches, relays, etc.) or an active CMOS-compatible logic system, and are used to control the activity of individual function modules. Logic outputs are used to report the status and results of function module activity to external control and annunciation devices.
