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

Time Relay/Set Point Generator
More specific units include; Time Relays with time ranges from
.20 sec. to 11 years with a 8 Amp relay contacts and the Set Point
Generator with an output range from 0 to 12V or 0 to 24mA, 20
program steps, and can produce sine, ramp, pulse, and DC as well
as other random waveforms.

Serial Interface/EzControl Software
Many of the discussed units are available with optional RS
232, RS 422, or RS 485 interfaces along with the control
software for your PC.
