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 3.0 VDC lithium battery will operate continuously for at least
7 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.
