C346
Preset Counter
Rate Meter
Time Counter
Introduction
The Veeder-Root brand C346 family offers a new level of performance in a 1/16 DIN
instrument. Fully programmable to operate as a preset counter, a rate meter (with
outputs) or an elapsed time counter. Enhanced fuctionality provides operating
modes for batching, background totalizing, and operation as dual counters with
master sum. When used as an elapsed time counter, the C346 offers unique
functionality for measurement of pulse widths or time between pulses. The C346 is
available with an LCD display or the industry's only 6 digit LED display for a 48mm
x 48mm product.
A wide variety of features are present that enable use in even the most demanding
applications. Inputs can be accepted from both NPN or PNP sensors, dry contacts or
encoders, and the input scaling function enables rate and count inputs to be
displayed in engineering units. Single and dual preset models are available and
each preset offers both a transistor output, which can interface to an external SSR
or PLC, and a relay output for
directly driving a load. The outputs
can be programmed for latching or
timed operation.
Even with a high level of
functionality, simplicity of operation
is still maintained. Important
parameters such as the preset and
prescale values can be called up
quickly with direct access keys
while an intuitive button per digit
interface enables those values to be changed easily.
The C346 has a NEMA 4 rated faceplate is CE approved, and UL and CUL listed.
