Digital Counter/Timer/Tachometer
CTT Series
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.
