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.

Features

• Choice of 6 digit LED or LCD Display

• Button Per-Digit setting and direct access

production totals

• 12 - 24 VDC sensor power supply

• Accepts either NPN or PNP inputs

• Relay and transistor outputs for each

preset

• Reset via front panel, remote input or

automatically
