DESCRIPTION

The DITAK 9 is a self-powered rate indicator designed to operate in

medium/high speed applications. It is ideal for use with magnetic pick-ups or

other bi-polar sensors operating at a minimum of 30 Hz*. The unit features

selectable timebase, rate multiplier, and decimal points via two front panel

pushbuttons. It has a 5-digit LCD Display with 0.46" high digits that are available

in positive image reflective (black digits, reflective background) or negative

image transmissive red or yellow/green (illuminated digits, dark background).

Backlight version units require power from an external 9 to 28 VDC supply.

The unit is constructed of a lightweight, high impact plastic case with a clear

viewing window. The sealed front panel meets NEMA 4X/IP65 specifications

for wash-down and/or dusty environments, when properly installed. A Ditak 9

unit can be mounted in the same panel cut-out as the earlier Ditak 7 units.

The optional Micro Line/Sensor Power Supply (MLPS1000) is designed to

attach to the rear of an installed backlight version Ditak 9. The optional supply

can be powered from an 85 to 250 VAC source, and can provide power for the

backlighting of a unit and a sensor. The maximum current draw for the sensor

is 45 mA.

* - For slow speed applications with low pulse rates, it is recommended to use

the CUB5 Counter/Rate Indicator.

SPECIFICATIONS

1. DISPLAY: 5-Digit LCD, 0.46" (11.68 mm) high digits.

2. POWER SOURCE: Internal 3.0 V lithium battery provides over 7 years of

continuous service (battery life is dependent upon usage).

3. BACKLIGHT POWER REQUIREMENTS: 9 to 28 VDC @ 35 mA.

Above 26 VDC, derate operating temperature to 50°C.

Must use the MLPS or a Class 2 or SELV rated power supply.

4. SIGNAL INPUT: 0 to 10 KHz from a magnetic or bi-polar output (with a

50% duty cycle). Min. input sensitivity is 0.9 V. Max. input = 28 V.

5. TIMEBASE: Adjustable in 1 sec increments via front panel. Timebase

ranges from 1 second to 7 seconds; 0.05% accuracy.

6. CONSTRUCTION: High impact plastic case with clear viewing window

(Panel gasket and mounting clip included). Installation Category I, Pollution

Degree 2.
