DÉBIT

Parrallel or serial link code receiver with display parallel or analogue, overflow threshold.

CODE CONVERTER CDC 9
The code converter receives a measurement :
  • either via a parallel code
    (normal binary, Gray code, BCD type),
  • or via a serial link code RS 232/V24


It send out :
  • A code (Gray, B.C.D. or natural binary).
  • 4 programmable thresholds.
  • A display.
  • 2 analogue outputs.
  • Depending on the cersion, it will give the input measurement or this linearized measurement according to the law introduced by the user, Q = f(h); Q = f(opening), etc ...
Applications
 
  • Receiver for modernizing NEYRPIC / NEYRTEC telemetry.
  • Off-loading the flow calculations from the main monitoring unit.
  • Flow calculation corresponding to the opening of a downloading valve.
  • Gray code or normal binary input display panel.
  • Alarm signals with the quantity to be measured.
    • Functions
      Parallel input
    The input parallel code comes from a mechanical encoder, another code converter or a levelmeter.

    Serial input
    The code converter receives periodically a message including the measurement.
    The serial link code may come from a LPN 8, or DPN 7, or CAE 7 or any other apparatus properly programmed.

    Front display
    The code converter includes an integrated LED display panel (six 20 mm digits).
    The display takes the offset into account (i.e. relating to local conditions).

    Analogue output
    Preset analogue outputs may operate according to 4 modes:

    1. Only one analogue output is used.
    2. The two outputs are used,
      • "Level" version: m and cm,
      • "Linearized" version: calculated measurement and initial measurement.
    3. The two outputs are independent from one another.
    4. The two outputs are "MODULO" types (magnifying effect).

    Preset thresholds
    The 4 thresholds deliver a relay contact (1 MB) when exceeding the prefixed value.

    Programmable coded outputs
    Whatever the entry code, the user chooses any of the 3 codes (natural binary, Gray, BCD) which are retrieved on relay outputs (1 make break).
