Glossary
ON-OFF ratio
The ratio of the ON signal time of a given input signal to the OFF sig-
nal time of the same input signal. The maximum counting speed of
each counter is determined by a counting input signal with an ON-
OFF ratio of 1:1.
Power consumption
The maximum wattage used by a device within its operating range at
the specified temperature and humidity.
Depending on the internal power circuit system of the model, both
apparent power and active power are indicated for the AC power
supply. Refer to the apparent power when designing a transformer.
Preset solid-state counter
A counter whose control output operates when it counts up to the set
value and which employs a semiconductor circuit for the counting
element.
Set value
Count value
Control output
Readout counter
A counter in which an output signal is normally generated corre-
sponding to the count value.
Reset
To restore the counting, display and output sections of the counter, to
their initial states.
Reversible-type counter
A counter with the capability of counting in an ascending or descend-
ing order, depending on the up-down inputs. Also called an up-down
counter.
Addition
Subtraction
Count value
Power reset
To reset the counter by cutting off the operating supply voltage.
Self-reset
To reset the counter by a signal generated by internal circuitry.
Shock resistance (destruction)
The threshold of shock beyond which an abnormality is expected to
occur in the appearance or function of a device.
Shock resistance (malfunction)
The threshold of shock beyond which a device can be longer operate
properly according to prescribed ratings
C-172
Stage
Number of preset values that correspond with the number of control
outputs.
Subtraction-type (Down/Decrementing) counter
A counter with a subtract input and thus capable of counting in
descending order.
Totalizing counter
A counter which indicates the total value of the counting inputs and is
not provided with a control output.
Vibration resistance (destruction)
The threshold of vibration beyond which an abnormality is expected
to occur in the appearance or function of a device.
Vibration resistance (malfunction)
There are several
