How To<br />
Choose Economical Counters, Digital<br />
Displays, and Process Controllers<br />
for your next production cell or assembly process<br />
As every process and assembly engineer realizes, design is<br />
a balance of cost and functionality. The correct choice of<br />
economical counters, process, and display units, will fulfill your<br />
counting & measurement and budget requirements. Bypassing the<br />
usual bulky and costly general measurement “boxes”, you can<br />
accomplish even better results using specific measurement and<br />
display modules. Using the Kuebler USA catalog as a reference, the<br />
following descriptions can guide your choices:<br />
Display Counters, Display Timers – Electromechanical<br />
Electromechanical counters and timers are the best pick when<br />
you need small size and a variety of shapes. Non-volatile by their<br />
mechanical design, their display is always available. A reset can be<br />
chosen and pick either AC or DC power. Mounting can be panel<br />
(front or back), Din rail, PCB, or base type. In<br />
general, their ultra low power consumption and<br />
very small size make them ideal for portable and<br />
battery powered equipment.<br />
Display Counters, Display Timers<br />
– Electronic<br />
Electronic counters and timers are available in<br />
LCD or LED displays, variety of shapes and sizes,<br />
and cased or stand alone modules. Power can be<br />
DC or AC, and some units will take both. Volatile<br />
by their nature, they are made non-volatile by<br />
using batteries or solid state memories. Displays<br />
can “turn off” when power is removed or be<br />
wired to always show their numeric results. If<br />
displays are “turned off” they would retain their<br />
last numbers for decades. Resets are available with<br />
local pushbutton, remote contact closure, or with serial interface.<br />
Mounting can be panel (front or back), Din rail, and PCB. Lighting<br />
is available as self lighting (LED) or backlit lighting (LCD). Electrical<br />
connections can be either by using provided wire leads, screw<br />
terminals, or connector headers. On advanced units, selecting<br />
functions and programming can be done thru front panel switches<br />
or with serial interfaces (if equipped). Output results can be display<br />
only, relay contacts, transistor outputs, optocoupler outputs, serial<br />
interface or analog outputs.<br />
Functionality of the units offers many choices<br />
as well. Straight time counting and incidence<br />
counting are the most basic. Totalizing, differential/up-down<br />
counting, position indication,<br />
multifunctional, pre-set values, and double<br />
functions are available.<br />
Tachometers/Frequency, Process Display/<br />
Process Controllers, and Temperature<br />
Display/Temperature Controllers<br />
These units extend the basic function of the<br />
electronic counters and timers to greater<br />
applications. Frequency measurements to 60kHz,<br />
scaling factors from .0001 to 99.999, adding,<br />
Kuebler Model 532 & 531 Digital Temperature Displays/Controllers<br />
subtracting, and totalizing. Also current and<br />
voltage measuring, input shaping with 24 control<br />
points, integration function, and 2 limit values.<br />
Temperature units display in °F or °C, galvanic<br />
isolation, resistance thermometer with up to 4 wire<br />
measurements, J K N thermocouples with cold<br />
junction compensation, and input shaping with<br />
24 control points.<br />
