OEM TRANSDUCER–FVC-DDZS - Differential Input Frequency to Voltage Converter Industrial Super Transducer. With Direction function, Zero and Span adjustments.

 

The TRANSDUCER–FVC-DDZS frequency to voltage converter is a pulse signal 1Khz or 10KHz  frequency to (Proportional) voltage super transducer board with unique output voltage polarity based on input direction, for CNC, HVAC (Heating, Ventilation and Air Conditioning), electro-hydraulic and servo electronics; actuator, dampers, bleed pilot valve, globe valves, butterfly valves, plug valves, dampers and more.

 

The TRANSDUCER–FVC-DDZS board is designed to perform frequency to voltage with direction conversion (transducer). If used properly, it will eliminate the need for an expensive board, which would otherwise be needed to carry out the same tasks.

 

The TRANSDUCER–FVC-DDZS  is easy to install, setup, and operate. If you want to do professional frequency to voltage or RPM measurement related functions, The TRANSDUCER–FVC-DDZS offers the features you need. It can be mounted easily via 0.125" mounting holes using 4-40 and / or 6-32 screws.

 

Simply connect the board to power connect your frequency pulse source 0 to 1KHz (or 0 to10KHz) to the input and it will convert it to 0 to 10V connect the direction input to ground and it will convert it to 0 to -10V (auto-polarity change).

 

Note: 1HZ = 60RPM therefore 1KHz => 60000 RPM and 10KHz => 600000 RPM. We chose output of 0 to +/-10V because standard PLC and industrial interface excepts transducers with 0 to +/- 10V input. Whoever we also have +/-5V models.

 

 

Our TRANSDUCER–FVC-DDZS OEM Frequency to Voltage Converter (FVC) with automatic direction function module transducer is designed to convert a continuous series of digital pulses (frequency) into an analog voltage. The board is ideal for a close loop control of a motor shaft. The input is designed to accept low level (as low as +/- 60 mV P-P) pulses from magnetic pick-ups or high-level square wave signals from a shaft encoder (as high as +/- 40 V P-P). Model depended; the output voltage is positive (0 to 10 VDC) or negative (0 to 10 VDC) with a magnitude proportional to the input frequency signal. This FVC board may be used to provide a unidirectional analog velocity signal that is directly proportional to the output from an encoder connected to a rotating shaft. The output maintains a signal linearity and drift too less than 0.3% with temperature drift of less than 0.05% per degree centigrade with a very low ripple, less than 30 mV P-P at 10 KHz. Each frequency to voltage converter module includes controls to set the output signal Zero and Span. Where the Zero output sets for zero input frequency (CW incises). And Span output sets to maximum input frequency (CCW incises). The board operates of 3 wires +/- 15 VDC power supply. The board’s Molex cage-up Terminal-Block makes it easy to connect to external connections and controls

 

The TRANSDUCER–FVC-DDZS Module delivers analog 0 +/- 10 VDC (or 0 to +/- 5 VDC) outputs proportional to input pulse rate (frequency) and direction. Where it accepts variable pulse rate inputs from a variety of sensors including magnetic pick-ups, with maximum linearity. It the ideal board for supplying velocity feedback in bi-directional closed loop speed control systems.

 

The Bipolar (Bi Polarity) Frequency to Voltage Transducer Direction function: The analog output voltage polarity automatically changes to  "FORWARD" (0 to VX) and  "REVERSE" (0 to -VX). NO NEED FOR ”POLARITY SELECT VIA HEADER SHORTING JUMPER BAR”! Where FORWARD, the analog output voltage polarity will be positive and "REVERSE" The analog output voltage polarity will be negative. The polarity of the output voltage changes automatically for a specific rotation direction set by the direction input of the transducer.

 

The Board operates on the frequency content of a Sinusoidal, Triangular, or Square waveform. Typical transducers include:

 A Magnetic Pick-up detecting a passing Gear-Teeth, Keyway, etc.

 A Photo-Eye that scans alternating opaque and transparent slots.

 A Digital Tachometer or Encoder.

For fast response of Board outputs, it is important that the transducer be located toward the high-speed end of the drive train. For slow shaft speeds, the transducer must be capable of delivering a high number of cycles or pulses per revolution. The transducer should also be capable of delivering a usable output for the entire speed range through maximum speed.
 

The following formula is convenient for relating machine speeds and sensor frequency output:

Frequency (CPS or Hz) = (RPM * PPR) /60

Where;

CPS is Cycle Per Second

RPM is the speed of the shaft where the sensor is located in Revolutions Per Minute.

PPR is the number of Pulses (or cycles) produced by the sensor for one shaft Per Revolution.

Super performance in is class; The Industrial board Zero and Span adjustment allows the unit to deliver full-scale output voltage for any input frequency within the limits of frequency range rating. It will provide an ultimate combination of fast response and low ripple.

 

This industrial grade transducer includes super output signal linearity and drift too less than 0.3 % as the ambient temperature and or input power supply voltage and are varied over the specified range.

 

The TRANSDUCER–FVC-DDZS circuit board is structure-utilizing bended throw-holes components that mean no problems down the road do to movement, (due to the natural use of the board in moving parts environment). No SOLDER MASKED component falling of the board during heat and movement! All external connections are made via “Molex cage-up type” terminal block.

 

The TRANSDUCER – FVC-DDZS transducer board is an accurate, linear, and an efficient way to convert industrial standards frequencies  0 to 1KHz, 0 to 10KHz into +/- 10V industrial standards or +/- 5V output voltages signals.... See below table "frequency to voltage industrial standard configuration models".
