K3HB Series (Pulse Input Series)
The K3HB Series has been made complete with
the addition of Digital Signal Input Models.
• Easy recognition of judgment results using two-color
display that can be switched between red and green.
• Equipped with a position meter for monitoring
operating status trends.
• External event inputs allows using various
measurement and discrimination applications.
• Series expanded to include DeviceNet models.
• Short body with depth of only 95 mm (see note)
(from behind the front panel).
• UL certification (Certification Mark License).
• CE Marking conformance by third party assessment
body.
• Water-resistant enclosure conforms to NEMA 4X
(equivalent to IP66).
Note:
Depth of 97 mm for DeviceNet 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.
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.
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.
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.

•
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.)

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.

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.)

Note:
The applications provided in this catalog are intended as reference only. Do not attempt to use any of them in real systems without first
confirming machine and device functions and safety. For applications that require safety, ensure that there is sufficient leeway in ratings and
performances, install fail-safe measures, and take any other safety measures required by the application. In addition, contact your nearest
OMRON representative and confirm specifications.
