Analog Input

Our block analog input module is designed to interface with voltage or current output devices to monitor factors such as pressure, flow, speed, position or temperature. We also offer a 6-channel resolver module, and an 8-channel J-K thermocouple module. These modules convert sensor signals into binary logic that the CPU can use.

Block Input Analog Module (4 Channel):

  • Interfaces the PiC with voltage or current output devices to monitor such things as pressure, flow, speed, position, or temperature
  • Four independent analog conversion channels
  • Each channel converts a unipolar or bipolar analog input voltage or current into a 14- bit digital value
  • Incorporates an internal current sense resistor for each channel for use with 0 to 20 mA or 4 to 20 mA devices
  • No user-adjustable potentiometers or hardware switches; all necessary gain adjustments are done in software

 

Block Input Resolver Module (6 channel):

  • Can interface to 6 independent resolvers (or equivalent transducers)
  • Feedback information from the resolvers is used to update the on-board memory
  • The position of each resolver can be read at any time by the PiC
  • The module generates two sine waves (RPO and QPO) 90° out of phase with each other, and each channel receives a signal whose phase represents the angular position of the resolver
  • The resolution of the angular position is 4000 counts per revolution or 0.09 degrees

 

Block Input J-K Thermocouple Module (8 channel):

  • Independent thermocouple or analog conversion channels receive signals from J or K type thermocouples or from a voltage source
  • Each channel converts an analog signal into a 14-bit digital word which is processed by the PiC CPU
  • Requires no hardware adjustments; all adjustments such as Fahrenheit or Celsius scaling and thermocouple ranges are software-selectable
