GENERAL DESCRIPTION
The Model C48 Counter is available as a Standard Counter or a Batch
Counter. The Standard Counter is available with single or dual presets. The
Batch Counter has a main process counter with dual presets and a secondary
counter with a single preset. The secondary counter can be selected to function
as a batch or a total counter.
The C48C features a 7 segment, 2 line by 6 digit reflective or backlit LCD
display. For the backlit versions, the main display line is red and shows the
count value. When preset 3 or output 3 is viewed in the secondary display, the
batch/total value is viewed in the main display. The smaller secondary display
line is green and can be used to view the prescaler value, preset values, output
time values or batch/total count values (Batch model).
The C48C offers a choice of nine programmable counting modes for use in
applications requiring bi-directional, anti-coincidence, and quadrature counting.
The unit may be programmed to register counts on both edges of the input signal
providing frequency doubling capability. DIP switches are used for input
configuration set-up and to provide a Program Disable function.
Four front panel push-buttons are used for programming the operating modes
and data values, changing the viewed display, and performing user programmable
functions, i.e. reset, etc. The C48C can be configured for one of two numeric
data entry methods, digit entry or automatic scrolling. The digit entry method
allows for the selection and incrementing of digits individually. The automatic
scrolling method allows for the progressive change of one through all digit
positions by pressing and holding the “up” or “down” button.
The C48 Counter has programmable User Inputs and a programmable front
panel function key. The user inputs can be configured as sinking (active low) or
sourcing (active high) inputs via a single plug jumper. The following functions
are available for user inputs and the front panel function key.
The Program Disable DIP switch, a user-programmable code value, an
external user input (selected for Program Disable), and the Accessible value
parameters can all be utilized to provide multi-level protection against
unauthorized changes to data values and unit configuration.
The Standard Counter with dual presets is available with solid-state or relay
outputs. The single preset model has a solid-state and relay output. The Batch
Counter has relay outputs for Output 2 and the Batch/Total Output (3), with
Output 1 available as solid-state. The Batch Counter is also available with three
solid-state outputs. For all C48 Counters, the solid-state outputs are available in
a choice of NPN current sinking or PNP current sourcing, open-collector
transistor outputs. All relay output boards are field replaceable.
A Prescaler Output model is available as a dual preset, with solid-state
outputs. The Prescaler Output is useful for providing a lower frequency scaled
pulse train to a PLC or another external totalizing counter. The Prescaler Output
provides an output pulse for every count, or every 10 counts registered on the
display.
Optional RS485 serial communication capabilities allow for interrogation
and modification of the preset, count, and prescaler values.
The unit is constructed of a lightweight, high impact plastic case with a
textured front panel and a clear display window. The front panel meets NEMA
4X/IP65 specifications for indoor use, when properly installed. Multiple units
can be stacked horizontally or vertically. Modern surface-mount technology,
extensive testing, plus high immunity to noise interference makes the C48
Counters extremely reliable in industrial environments.
Safety Summary
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit.
