General Description
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, 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 double-line, 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,
included panel mounting clip and gasket make panel mounting a snap. The CTT is available in 120-240VAC
and 24VDC powered models.
