Spectrum Controls 140EHC20400sc
Spectrum Controls 140EHC20800sc

The 140 EHC20400sc and 140EHC0800sc provide Quantum™ Automation Series CPUs the capacity to handle a wide variety of count and flow applications. The modules feature four or eight incremental counter or turbine flow meter inputs. For counting applications, each input can count to rates of 50KHz. When inputs are used in pairs, they can be configured for up/down and quadrature counting. The modules also feature typical turbine flow meter setup parameters such as K (scaling) and M (calibration) factors in addition to input control lines for meter proving.

Simplifies Installation
The modules incorporate proprietary Schneider Automation technology allowing it to operate like other Quantum products for easy installation. The modules allow you to use up to eight inputs structured as four groups of two inputs. Each of the input groups can be configured as 5, 12, or 24 Vdc counters or as turbine flow (variable reluctance coil) AC inputs.

Outstanding Features
The Quantum™ PLC Counter includes a variety of helpful features:

Setup for incremental, up/down or Quadrature counting
Scaling of input counts or input frequency to engineering units
Simultaneous frequency / count display
Flags can annunciate when a zero or limit has been achieved
Over-range flag when count or frequency exceeds a preset limit
Start, stop, reset and preset control

This module resides in a standard Quantum™ PLC backplane and offers:

versatility through the module’s unique ability to interface to different sensor types without any signal conditioners.
robustness through over voltage protection active band pass filtering. Features 1000 Vdc channel-to-backplane isolation.
value through reduction of installation cost. Meters may be interfaced directly to the module. No additional external conditioning devices are necessary.
flexibility through a wide variety of user selectable features to help tackle almost any job.
ease of installation with support from Modicon® Concept™, Modsoft™ and ProWORX™ programming software. The module is easily configured using ladder register settings.

Designed for data acquisition in process industries such as utility, waste water, oil and gas, food and beverage, or building automation, the 140EHC20400sc and 140EHC20800sc modules are the ideal solution for those who need to acquire signals from a large number of sources within an individual process or throughout a facility.
