Digital Indicators K3HB Series (Pulse Input Series) 1
Digital Indicators
K3HB Series (Pulse Input Series)
The K3HB Series has been made complete with
the addition of Digital Signal Input Models.
Features
Red-Green Display Allows Easy
Recognition of Judgment Results
The measurement value display can be set to switch between red
and green in accordance with the status of comparative outputs. This
means that the status can be easily seen at a distance.
Position Meter Enables Easy Monitoring of
Operating Status Trends
The present value with respect to the measurement or display range
(full scale) can be viewed on a bar display. The operating status can
be grasped intuitively, allowing easy judgment of levels and threshold
values.
Short Body with Depth of Only 95 mm
(from Behind the Front Panel)
A short body of only 95 mm (see note) contributes to the
development of slimmer and smaller control panels and installations.
Note: Depth of DeviceNet models is 97 mm.
50 kHz High-speed Pulse Measurement
(K3HB-R)
Supports high-speed pulse measurement (up to 50 kHz) of rotary
encoders or any ON/OFF pulse signal, which enables rotational
measurement of objects rotating at high speeds.
Note: No-voltage contacts of up to 30 Hz are supported.
Measurement of Wide Range of Pulse
Interval Times (K3HB-P)
Measures and displays the results of the pulse interval between two
points. The pulse interval measurement range is broad, from 10 ms
to 3,200 s.
High-speed Up/Down Counting Pulse
Measurement (K3HB-C)
Perfect for high-speed measurement of rotary encoders or any
ON/OFF pulse signals. Cumulative pulse input is 50 kHz, quadrature
pulse inputs are 25 kHz, and up/down pulse inputs are 30 kHz.
Note: No-voltage contacts of up to 30 Hz are supported.

2Digital Indicators K3HB Series (Pulse Input Series)
Features
Many I/O Variations for Discrimination, Control, and Information Applications
Digital Indicators are used in a wide variety of applications, from an electronic measurement value display or equipment/device operating status
display to a host communications interface in monitoring and control systems. OMRON provides a complete lineup for a variety of input and control
output applications to meet all your application requirements.
Select a Comparative Output Pattern to
Suit the Discrimination or Control
Application
•The output pattern for comparative outputs can be selected. In
addition to high/low comparison with set values, output based on
level changes is also possible. (Use the type of output pattern
appropriate for the application.)
Note: The HH, H, L or LL outputs must be set in that order for the zone
outputs to output correctly.
(This is because the comparative set values and outputs for
standard and level outputs are in a 1-to-1 relationship, whereas
the meaning of zone outputs depends on the settings of all the
comparative set values.)
Lineup Includes DeviceNet Models
Enabling High-speed Data
Communications with PLCs without
Special Programming
•DeviceNet compliance enables high-speed data transmission by
allocating setting and monitoring parameters in the I/O memory of
the PLC. This capability greatly reduces labor spent in developing
communications programs.

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.

Rotary Pulse Indicator K3HB-R 9
■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.

Operation
■Functions (Operating Modes)
F1 to F6
These functions use the internal system clock to measure the time between pulses or the pulse ON time and then display time measurements or
a variety of other calculations.
Function name Function No.
Passing speed f1
Cycle f2
Time difference f3
Time band f4
Measuring length f5
Interval f6
The time (T) between input A pulse and input B pulse
is measured by the internal system clock. If, for
example, the system clock measures 100,000 counts
during time T, then
T = 1 system clock count (0.5 µs) ×100,000
T = 0.05 s
F1 (the passing speed) is calculated internally
using the formula × 60 (m/min), and the
display, in this example, would be ×60=
1200 (m/min).

■What Is Prescaling?
To make calculations using the input pulse to display the passing speed between two points, the distance between the two points and the display
unit must be set and the internally measured time multiplied by a certain coefficient. This coefficient is called the prescale value. (For information
on settings details, refer to the User's Manual.)

the length per pulse = 500 mm (0.5 m) ÷250 = 2.
1. The prescale value for the K3HB-C is set using the mantissa X ×exponent Y,
so the prescale value = 2.0000 × 10°,
X = 2.000, and Y = 00.
