Rotary Pulse Indicator
K3HB-R
Digital Rotary Pulse Meter Capable of 50 kHz Measurements
• Visual confirmation of judgement results through display colors that switch
between red and green. *1
• Measures High-speed Pulses at 50 kHz.
Provides high-speed pulse measurements up to 50 kHz of rotary encoder or ON/OFF pulse
signals and can perform rotating measurement of high-speed rotating objects.
Note: No-voltage contacts of up to 30 Hz are supported.
• Six Measurement Operations Including Rotation (rpm)/Circumferential
Speed, Ratio, and Cumulative
One Rotary Pulse Meter has 6 rotary pulse measurement functions to support a variety
of pulse measurement applications. Select the best function for your application from the
following: Rotation (rpm)/circumferential speed/instantaneous flowrate (value
proportional to frequency), absolute ratio, error ratio, error, flow rate ratio, and passing
speed (value inversely proportional to frequency).
• DeviceNet models added to the series. *2
*1 Visual confirmation of judgement results is not supported on models that do not have an output
or models that do not support DeviceNet.
You can change the display color by setting it, but you cannot switch it based on the judgement results.
*2 DeviceNet models have a depth of 97 mm.

F2 to F5: Displays the calculation result for two rotation (rpm) speeds.
F6: Displays the passing time calculated from the circumferential speed and the length
of the processing stage for one input.
The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is
to count the ON/OFF time (T) for input sensor or other device inputs using the internal system
clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and
displayed as the rotation (rpm) speed.
Input sensor or other input pulse ON/OFF time (T) = Frequency (f) =
•Rotation speed (rpm) = f × 60
•Circumferential speed = Roll circumference × Rotation speed (rpm)
•Passing time=
These calculations are automatically made internally and displayed whenever any input pulse
is received.

■What Is Prescaling?
To make calculations using the input pulse to display rotation (rpm)
or circumferential speed, the number of pulses per rotation or the
length of the circumference must be multiplied by a certain
coefficient. This coefficient is called the prescale value.
Rotation speed (rpm) = f × 60 × a
f: Input pulse frequency (No. of pulses per second)
a: Prescale value
If there are 5 pulses per rotation, then
a = 1/5 (= 0.2 = 2 × 10-1)
and an accurate rotation speed (rpm) can be calculated.
The actual setting is X = 2.0000 (mantissa) and Y = 10-1 (exponent).
■What Is the Auto-zero Function?
(Set this function before using the Digital Indicator.)
If a function f1 to f6 is set, the frequency can be force-set to zero if
there is no input pulse for a set period. This period is called the auto-
zero time. Set the auto-zero time to slightly longer than the longest
input pulse interval. (The display will not easily return to zero if the
auto-zero time is too long or left at the default setting.)
Time Unit Settings
Note: Time unit can be set only when passing time (F6) is selected.
Input Type Setting
Note: Set to 10 or 11 when there is a large variation in the display.
The largest measurement range is 30 Hz.

■Derating Curve for Sensor Power Supply (Reference Values)
For 12V
Note: 1. The above values were obtained under test conditions with the standard mounting. The derating curve will vary with the mounting
conditions, so be sure to adjust accordingly.
2. Internal components may be deteriorated or damaged. Do not use the Digital Indicator outside of the derating range (i.e., do not use it in
the area labeled A, above).

■BCD Output Timing Chart
A REQUEST signal from a Programmable Controller or other external device is required to read BCD data.
Single Sampling Data Output
The data is set in approximately 30 ms from the rising edge of the
REQUEST signal and the DATA VALID signal is output.
When reading the data from a Programmable Controller, start
reading the data when the DATA VALID signal turns ON.
The DATA VALID signal will turn OFF 40 ms later, and the data will
turn OFF 16 ms after that.
Continuous Data Output
Measurement data is output every 64 ms while the REQUEST signal
remains ON.
Note: If HOLD is executed when switching between data 1 and data
2, either data 1 or data 2 is output depending on the timing of
the hold signal. The data will not go LOW.

■Dimensions
Wiring Precautions
•For terminal blocks, use the crimp terminals suitable for M3 screws.
•Tighten the terminal screws to the recommended tightening torque
of approx. 0.5 N·m.
•To prevent inductive noise, separate the wiring for signal lines from
that for power lines.
Wiring
• Use the crimp terminals suitable for M3 screws shown below.
Unit Stickers (included)
•No unit stickers are attached to the Digital Indicator.
•Select the appropriate units from the unit sticker sheets provided.
Mounting Method
1. Insert the K3HB into the mounting cutout in the panel.
2. Insert watertight packing around the Unit to make the mounting
watertight.
3. Insert the fixture into the grooves on the left and right sides of the
rear case and push until it reaches the panel and is fixed in place.
LCD Field of Vision
The K3HB is designed to have the best visibility at the angles shown
in the following diagram.

If the rubber packing is lost or damaged, it can be ordered
using the following model number: K32-P1.
(Depending on the operating environment, deterioration,
contraction, or hardening of the rubber packing may occur and
so, in order to ensure the level of waterproofing specified in
NEMA4, periodic replacement is recommended.)
Note: Rubber packing is provided with the Controller.

Main Functions
■Main Functions and Features
Measurement
The K3HB-R has the following six functions for receiving and
displaying input pulses.
F1: Rotation (rpm)/circumferential speed
F2: Absolute ratio
F3: Error ratio
F4: Rotational difference
F5: Flow rate ratio
F6: Passing time
The K3HB-P has the following six functions for receiving and
displaying input pulses.
F1: Passing speed
F2: Cycle
F3: Time difference
F4: Time band
F5: Measuring length
F6: Interval
The K3HB-C has the following three functions for receiving and
displaying input pulses.
F1: Individual inputs
F2: Phase differential inputs
F3: Pulse counting input
Filters
Average processing of input signals with extreme changes or noise
smooths out the display and makes control stable.
Specify the types of sensor connected to input A and input B.
Input Compensation
The frequency is forced to zero if there is no pulse input for a set
period.
Key Operations
The present measurement value can be used as a scaling value.
Key protection restricts level or parameter changes using the keys to
prevent unintentional key operations and malfunctions.

Outputs
Standard, zone, and level comparative output patterns can be
selected for comparative outputs.
Prevents comparative outputs from chattering when the
measurement value fluctuates slightly near the set value.
Holds the output status when a comparative result output other than
PASS turns ON.
Comparative results other than PASS can be output from the PASS
output terminal.
Delays turning OFF comparatives for a set period. This can be used
to provide sufficient time to read the comparative output ON status
when the comparative result changes at short intervals.
Turns ON the comparative output for a specific time.
Reverses the output logic of comparative results.
Measurements can be stopped for a set time using an external input.
Output operation can be checked without using actual input signals
by using the keys to set a test measurement value.
A current or voltage proportional to the change in the measurement
value can be output.
The comparison outputs can be kept OFF until the measurement
value enters the PASS range.
Display
The display value can be set to the present value, the maximum
value, or the minimum value.
The present value display color can be set to green or red. The color
of the present value can also be switched according to the
comparative output.
When the input changes rapidly, the display refresh period can be
lengthened to control flickering and make the display easier to read.
The present measurement value can be displayed as a position in
relation to the scaling width on a 20-gradation position meter.
The input signal can be converted and displayed as any value.
Select whether or not to display the comparative value during
operation.
Automatically returns the display to RUN level when there are no key
operations (e.g., max./min. switching, bank settings using keys).
Other
Holds the maximum and minimum measurement values.
Switch between 8 comparative value banks using the keys on the
front panel or external inputs. A set of set comparative values can be
selected as a group.
Any bank settings can be copied to all banks.
