General Description
The
2000CT Combined Counter/Tachometers
*
are 6-decade seven segment LED display
instruments based on the industry standard Intel 80C51 series microprocessor. They are built into
half DIN (96 mm x 48 mm) panel mounting housings and can be supplied to operate on 115V or 230V
AC or 24V DC power supplies (see
The
2000CT
is designed to accept a pulsed signal from either one or two sources and the display can
be switched to show the rate of the input signal or the total count as and when required. Both options
are continuously monitored and either may be instantaneously selected by pressing a button on the
front panel. A high and low alarm can be set for the rate value and the appropriate output will be
activated when the value falls outside either limit.
The displayed values are scaled so that one unit on the display can represent a pre-set number of
input pulses. In addition to this scaling there is the facility for individual scaling of the total display
and the rate display so that rate may be displayed as units per second, units per minute, units per
hour, milli-units per second etc., and total can be displayed as units, milli-units, kilo-units etc. An
option is available for output of the rate value in a fully scalable analogue form, either current or
voltage.
2000 Series
instruments are available with several factory fitted options which must be specified
when ordering — see
on page 3 for details. Additionally,
Logitech
will customise the
programmed operating modes of these instruments to suit specialised applications. Many variations
on the standard software have been developed — please contact our Sales Office if this service is
required.
Note:
Two versions of
2000 Series
instruments are available - either with a
full
switch set accessible
externally on the front panel, or with only a
single
function switch (
FUNC
) accessible unless the
bezel and front panel are temporarily removed. The following setting up instructions assume the front
panel has been removed if using a
single
switch version.

In some industries these type of instruments may be described as “Totaliser/Ratemeters”
