CTT Series - Digital Counter / Timer /
Tachometer
Features
• Can operate as a digital counter, timer, combination
timer + counter or tachometer
• Accepts voltage and non-voltage inputs from a wide
variety of NPN, PNP, or dry contact sensors
• Selectable counting speeds from 1 to 10,000 cycles
persecond
• Multiple transistor and relay outputs can operate as
momentary or maintained • Double-line, 6-digit, 2-color LCD display • Easy configuration with externally accessible DIP
switches or the lockable keypad
• Display decimal point selection • Available in 100-240VAC and 24VDC powered
models • UL508 listed (E311366), cULus, CE marked A lot of functionality in one powerful little unit!
The CTT series is an extremely versatile multi-function device that is easily
configured for operation as a digital
counter, timer, combination timer +
counter, or tachometer. Both voltage
and non-voltage inputs are accepted
from a wide variety of sensor types with
NPN, PNP, or dry contact outputs. The
first output on the CTT is a single-pole,
E311366
single-throw relay and NPN transistor
that operate concurrently. The second
CTT output can be ordered as either a
single-pole, double throw relay or NPN
transistor. Parameters are easily set using
the externally accessible DIP switches
or the lockable keypad. The doubleline, 6-digit, two-color LCD display
shows the counter, timer, or tachometer
present values, setting values and menu
parameters during set-up. Additional
individual indicators are provided for
inputs, outputs and functions. The standard 1/16 DIN size, with included panel
mounting clip and gasket, make panel
mounting a snap. The CTT is available
in 100-240VAC and 24VDC powered
models.

Signal On Delay 1 (Sond1)
With power applied to the CTT, the leading edge of the input
signal at START will begin the timing period setting value SV
(timing up or down based on parameter (t modE) or by DIP
switch 2). At the end of the timing period both outputs will
turn ON momentarily for the time set in the output pulse width
parameter (tout1) or will be maintained ON if the output
pulse width parameter (tout1) is set to 0.00. The trailing
edge of the “start” signal has no effect on the outputs or timing
period.
The leading edge of a “reset” input signal at RST1 will turn
OFF the outputs and reset the timing period. The “reset”

Timer Example:
A basic Timer used to control the clamp time of a compression model
press. When the operator signals, the mold is loaded with material. When
a start button is pressed, the hydraulic cylinder closes the press to make a
limit switch which starts the CTT timing. Upon completion of the timer cycle,
Output 1 is turned on and the press is opened by the hydraulic cylinder.

Tachometer Example:
Using PSCALE to convert pulses into engineering units
T he PSCALE feature of the CTT is very useful in converting the
pulsed signal from an encoder or sensor into a usable unit of
measurement.
or example, if connecting a proximity switch to the CTT to
F
monitor the speed of a motor using a sensing gear, there is
a simple calculation to convert the pulses from the sensor to
Motor RPMs.
Reset
Output 1
For example, in the illustration below, there are 38 teeth on the
gear or 38 ppr. If the gear is coupled directly to the motor, this
is all that is required to perform the calculation.
PSCALE = 60/ppr or 60/38
PSCALE = 1.579
With the PSCALE set to 1.579 for every 38 input cycles the CTT
will display a value of 1.
sing the following formula, you can calculate a PSCALE value
U
to change a pulse signal into RPMs. First, obtain the pulses per
revolution (ppr) or number of teeth on the sensing gear.
