ALARM SETTERSD SERIESDEVIATION ALARM SETTERSDDV - 105 LCD TYPE

■ UseA compact plug-in setter for instrumentation. The device inputs two
DC signals, calculates deviation between inputs and deviation of each
input, compares the results with preset signal, then outputs theover-and-short. Because the device is software compatible, besides fullscale of input can be set at will in accordance with process quantity,each setting value (operation value, moving average constant, contactdelay, etc) can be set and changed freely as well. Also, input (actualscale) and each setting value can be displayed by a LCD (with backlight) in 4 digits.

SDDV-105(80×50×133mm/380g)■ Features
1. Setting accuracy ±0.5%
2. Indication accuracy ±0.5% ±1digit.
3. Withstand voltage between input/output/power source/outer case is AC2, 000V.
4. Display and setting of actual scale by LCD can be done freely with front SW button, also suitable for scalingchange and so on.
5. Setting values are stored in a nonvolatile RAM and are free from the affection of a power failure.
6. By sufficient derating of parts used and reduction of internal heat generation, liability is improved.
7. Back light turns on during key operation. It turns off automatically 30 sec. after key operation finished.

DC power source4.5W● UR-1 precise resistance unit (Sellingseparately)
Use UR-1 combined with an alarm setter of voltage
input. When changing the alarm setter in a hot line
state at the time of current input, if measures against
open are necessary, connect UR-1 to socket and convert
it into a voltage signal before using it.
