Measure High-speed Up/down Pulses with this
Up/down Pulse Meter.

• Visual conf0rmation of judgement results through display colors that

switch between red and green. *1

•

Perfect for Measuring Rotary Encoder and ON/OFF Pulse Signals at High
Speed

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 count value can be converted to any value.

The length equivalent for any pulse can be set to any desired value. This is
effective for feed amount and position monitor displays.

• 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.

Refer to Safety Precautions for All Digital Panel
Meters.

inputs

Counts input A as incremental pulses and input B as
decremental pulses. The count is incremented on the
rising edge of input A and decremented on the rising
edge of input B. If both inputs rise at the same time, the
count is not changed. The count is incremented when
input B is later than input A and decremented when input
B is earlier than input A.

■ What Is Prescaling?

K3HB-C

Encoder

0.5 m

250 pulses

Prescaling converts the count value to any numeric value.
To d i sp l ay @@@@.@ mm in a system that outputs 250 pulses for a 0.5-m feed,

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.

2. Next, set the decimal point position for one digit to the right of the decimal point:
