DESCRIPTION
The Ditak 8 is a self-powered rate indicator which features selectable
Timebase Increments by setting the appropriate DIP switches on the rear of the
unit. The internal 3.6 VDC lithium battery will operate continuously for at least
5 years. It has a 5-digit LCD display with 0.6 inch (15.2 mm) high digits. The
displays are available in positive image reflective (black digits, reflective
background) or negative image transmissive (illuminated digits, dark
background) with red or yellow/green backlighting. 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.
The optional Micro Line/Sensor Power Supply (MLPS1000) is designed to
attach to the rear of an installed Ditak 8. The optional supply can be powered
from 85 to 250 VAC, and can provide power for the backlighting of a unit and
most sensors.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
SPECIFICATIONS
1. DISPLAY: 5-Digit LCD, 0.6" (15.2 mm) high digits.
2. POWER SOURCE: Internal 3.6 V lithium battery provides over 5 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 MLPS1
or an NEC Class 2 or Limited Power Source (LPS) 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 VDC.
5. TIMEBASE: Adjustable in 1/256 sec (3.906 msec) increments via DIP
switches located at the rear of the unit. Timebase ranges from 3.906 msec to
63.99 sec; 0.01% ±1 digit accuracy.
6. ENVIRONMENTAL CONDITIONS: Operating Temperature: 0 to 60 °C
(Above 50 °C derate backlight operating voltage to 26 VDC max.)
Storage Temperature: -40 to 80 °C
Operating and Storage Humidity: 85% max. (non-condensing) from 0 °C
to 60 °C.
