Model MSCF2V04 Frequency to Voltage Converter

FLEXIBLE INPUTS:

  • Accepts most encoders and magnetic pickups
  • Four fully differential "frequency signal" inputs, accommodate a wide range of signal amplitudes
  • Two additional digital inputs, for position index signals from quadrature encoders
  • One analog input, allows calibration to an external reference (e.g., analog fifth wheel)

CONFIGURABLE OUTPUTS:

  • Very FAST: outputs are updated on every period of the input signal
  • Provides both velocity & position analog outputs when in quadrature mode
  • All inputs and outputs fully scalable, using USB port and included Windows® software
  • LED display, with four channel selector

Description

Michigan Scientific's MSCF2V04 is an extremely versatile frequency to voltage converter. Using the supplied User Interface software, the user can configure the MSCF2V04 to produce voltages proportional to the frequency (or the count) of incoming pulses. This allows for a simple measurement of rotational velocity, speed, position, and pulse count.

Typical Applications:
Measurement of rotational speed variation of engines and motors
Engine / motor startup and shutdown characteristics
Wheel speed measurement (such as ABS and traction control system testing)

Flexible Inputs:
The MSCF2V04 can accept both Individual (single-phase) and Quadrature signals, plus an OPR-Index ("once-per-rev." positioning pulse) for each quadrature pair. 
The pulse inputs (4 Channels + 2 OPR-Indexes) are fully differential, accept up to ±120V amplitude pulses, and provide up to 1500V of isolation.  Configure each Channel input for either TTL-threshold (digital square-wave), or Mag Pickup (magnetic reluctance type sensor) signals. Adjust Input Offset of each Channel up to ±10V.

Configurable Outputs:
Each channel's output is updated immediately at every input pulse.  These 16-bit analog outputs are scalable to ±10V (or less), and the full-scale input frequency is adjustable to almost any value as well.
The Minimum Measurable Frequency can be adjusted from 0.15 Hz to 610 Hz. The maximum aggregate frequency is 124 kHz for High Speed mode, 68 kHz for Quadrature mode, 72 kHz for Normal Speed mode, and 180 kHz for Pulse Count mode.

Additional Features:
For wheel speed applications, an ABS Algorithm can be used to quickly detect wheel lock-up.
The digital display can be configured to display each channel's output voltage, trigger status, or rotational velocity and position (Quadrature mode).
A 16-bit Analog Input is available to calibrate the pulse-Channel(s) to an external reference, such as an "analog fifth wheel" vehicle-speed sensor.
