A hybrid IC that allows you to integrate F/V conversion functions (or F/D conversion for the FUD-16) directly onto your own circuit boards, powered by our proprietary Periomatic-B method.
Universal specifications allow you to configure custom full-scale conversion values for inputs ranging from 0.006 Hz to 500 kHz. Achieve high precision, rapid response times, and simplified system design.
Provides advanced backward compatibility with the legacy KAZ-7400 model. Simply drop it in to replace older units and immediately benefit from 16-bit high resolution and low calculation noise performance.


Rotary Encoders

| High-Precision Gating System
COCORESEARCH's proprietary frequency measurement technology, Periomatic-B. It precisely measures and averages the number of pulses and periods within the gate time, eliminating pulse count errors typical of standard gating systems and performing robustly against pulse irregularities. |
| High Accuracy Under Drastic Changes
One of the key strengths of Periomatic is its predictive computation, ensuring high accuracy even during abrupt speed variations. You can configure the optimal deceleration/stop response according to the specific stopping characteristics of the rotating body. |
| 16-Bit High Resolution for I/O
Features a high-speed clock achieving an input resolution of 42 ns and a voltage resolution of approx. 1/57,000 at 100% output voltage. |
| Ultra-Wide Range Support
Supports a wide range from 0.006 Hz to 500 kHz, allowing you to define any custom measurement range. |
| Backward Compatible
Easily replace the KAZ-7400 to upgrade your system's input/output resolution and overall performance. |
| 4 Types of Output & Mounting
Four distinct models are available: Analog or Digital output, with either Horizontal or Vertical mounting configurations. |
| Spread Function
The spread function allows you to magnify and measure specific desired measurement sub-ranges. |
| Logarithmic Output
Outputs the entire range logarithmically at once. Custom range selection is available. |
| Frequency/Period Selector
Select whether the output is directly proportional to the frequency or to the period. |
| Input Pulse Averaging
Automatically compensates when pulse cycles are uneven within the gating period. |
| Chatter Suppression
Suppresses chattering noise from relay contacts, photocouplers, and other signal sources. |
| Dual Range *
Allows you to switch dynamically between two different full-scale range settings. |
| Maximum Value Hold *
Holds and displays the highest frequency captured during the measurement period. |
| Minimum Value Hold *
Holds and displays the lowest frequency captured during the measurement period. |
| Current Value Hold *
Locks and holds the specific measurement value at the exact moment the hold command is triggered. |
| Stepless Smoothing
Converts step-like outputs occurring at every gate update interval into a smooth, continuous line graph output. |
| Comparator Output
Compares the input signal frequency with preset thresholds to evaluate high/low status limits. |
| Standstill Detection
Detects complete stops or standstills by setting the comparator threshold close to zero. |
Averaging Functions (Pulse, Time, and Moving Average) > Learn More
Integrated processing functions for pulse, time, and moving averages enable accurate recording and analysis of erratic rotation or intermittent movements. Highly effective for low flow rate measurements.
FUV Series (Analog Output Type)
Analog Output Update Time: 1 ms to 99.999 s
Adjustable in 1 ms increments.
Effortless Specification Mapping
Easily configure specifications via a handheld program loader or from a PC using a USB communication cable. All configured settings are reliably stored in the internal EEPROM.
FUD Series (Digital Output Type)
Direct Frequency-to-Digital Conversion for Superior Tracking
Eliminates offset errors, minimizes span errors, and ensures exceptionally low temperature drift.
Enhanced Precision and Speed Over Traditional Analog F/V + A/D Chain
Eliminates A/D conversion errors and avoids time-lag bottlenecks since no conversion processing latency is required.
CMOS Level Serial Output for F/D Conversion Data
Enables highly compact system architecture and miniaturization.
User-Friendly System Parameters
Configure technical parameters via direct communication with an MPU, a dedicated setting terminal, or serial communication with a PC. Designed for effortless integration into microcomputer-driven architectures. Configured baselines are saved in the onboard EEPROM.
Connect a PC to a device equipped with this IC (such as the COCORESEARCH Evaluation Board EMB-74X, sold separately) using a USB communication cable (such as the BXI-UK1, sold separately) to manage settings, logs, and printouts via LINKSHIP.
Core Features: Read parameter maps from device / Write settings to device / Save profile data to PC / Verify and compare multiple data profiles / View technical product documentation
*The BXI-UK1 USB communication cable does not supply bus power.
*Separate external power supply is required for the EMB-74X (DC +5V / +15V / -15V).
