5D78S

The single-channel Models 5D78 and 5D78V are similar to the DC-excited Models 5D70 and 5D70V, respectively, but feature a highly effective phase-sensitive carrier-amplifier design. Three selectable operating frequencies are provided to best match the user's specific transducer.

The 5D78 delivers filtered analog output of ±5 VDC, while the 5D78V produces ±10 VDC.

The 5D78(V)'s advanced analog design directly addresses the problem of measurement inaccuracy in industrial environments of high electromechanical noise.  Exceptional signal stability and accuracy over the entire input range are achieved through

  • regulated, remotely sensed AC excitation
  • precise LINEARITY / SYMMETRY correction and SIGNAL PHASE adjustment via software commands
  • high-stability amplification
  • configurable low-pass active filtering
  • "absolute" and "two-point" software-based calibration
  • effective signal isolation and ESD protection

While intended primarily for applications involving transformer-coupling to the transducer bridge (as with conventional rotary-transformer torque sensors), the Model 5D78(V) can also be used when high sensitivity is required or where the electrical environment is especially noisy.  Responding only to the modulated carrier frequency, the module rejects extraneous voltages that can cause errors in DC systems, particularly when there is a need to "blow up" a portion of the transducer range.

For both the Model 5D78V and the Model 5D78S (the "S" Option version of the Model 5D78), a 10-pin header for a Phoenix Style screw-terminal connector replaces the Model 5D78's standard DB25 connector for the module's power, configuration, logic, and analog output wiring.  Ensuring secure cable connections to individual 5D modules, these versions are intended primarily for single-point or single-mount module applications.  Since the logic "enable" line is not provided in this case, both analog outputs are continuously available for both the 5D78V and the 5D78S.
