Overview
This chapter describes the 4- or 8-channel Quantum Counter/Flow Meter input module (called “Quantum
counter” module in this document). It also explains how the Schneider Automation Series Quantum PLC reads
input data from a Quantum counter module.
Shipped with your module is an MS-DOS formatted floppy disk titled “Quantum Runtime Files,” Spectrum
Controls, Inc. The disk contains runtime files that are required to use all versions of this module. Files include
an ID file, parameter screen software, and multiplexing software examples for 4X and 3X register use.
NOTE The module is used with a field wiring terminal block, Modicon 140 XTS 002 00 or 140
CFA040 00 40-pin cablefast. Either of these must be ordered separately.

General Description
The Quantum counter module is designed for general-purpose counter and flow meter applications that require a
large number of input channels and high accuracy. It supports both AC and DC input signals from counter and
flow meter encoders (both normal and quadrature). The module conditions the inputs to standard digital levels.
It stores the converted data in its image table for retrieval by any Quantum PLC.
The module communicates with the PLC and receives its power through the PLC backplane from the +5VDC
rack power supplies. No external power supply is required.
Your Quantum counter module supports connections from any combination of counter and flow meter devices,
with different input voltage ranges. Each channel is individually configurable via software for a specific input
device and provides rate and limit detection. Count mode and input range are configured in two channel groups.
