Chapter1OverviewThis chapter describes how analog is used and provides twoapplication examples of analog. The types of available analogmodules and their related specifications are also described.How to Use AnalogAnalog refers to the representation of numerical quantities by themeasurement of continuous physical variables. Analog applicationsare present in many forms. The following application shows a typicaluse of analog.In this application the processor controls the amount of fluid placed ina holding tank by adjusting the percentage of the valve opening. Thevalve is initially open 100%. As the fluid level in the tank approachesthe preset point, the processor modifies the output to degrade closingthe valve 90%, 80%, adjusting the valve to maintain a set point.Analog OutputValveCPULevel SensorAnalog I/OModuleAnalog InputTypes of Analog Modules1The following sections provide an overview of the various analogmodules.Publication 1746-UM005B-EN-P - June 2004

In thisexample procedure, local slot 1 is selected.Top and Bottom ModuleRelease(s)Card Guide5.Wire the module.Important:Follow these guidelines when wiring the module. Use shielded communication cable (Belden 8761) and keep length as short as possible. Connect only one end of the cable shield to earth ground. Channels are not isolated from each other. All analog commons are connected togetherinternally. The module does not provide power for analog inputs.

3-2Installing and Wiring Your Analog ModuleDetermining Your PowerRequirements for aModular ControllerAnalog modules require both 5V dc and 24V dc power from thebackplane of the SLC 500 system. However, the NO4I and NO4Vanalog modules can use an external 24V dc power supply. Thiseliminates the 24V dc backplane power requirement, providingconfiguration flexibility if SLC power supply loading is critical. Thesetwo modules provide user-supplied external 24V dc power supplyconnections.The 24V dc user power connection on a fixed SLC 500 can power anNO4I or NO4V analog module. However, the regulation of the 24V dcuser connection on a modular SLC 500 power supply, Catalog Number1746-P1, -P2, -P4 is outside of the requirements of the NO4I andNO4V analog modules and cannot be used.The following table shows the power requirements for each analogmodule using backplane power. Use this table to calculate the totalload on the modular system power supply. For more information referto the SLC 500 user manual for modular controllers.IMPORTANTCatalog Number5 Volt Current24 Volt Current1746-NI435 mA85 mA1746-NIO4I55 mA145 mA1746-NIO4V55 mA115 mA1746-NO4I55 mA195 mA(1)1746-NO4V55 mA145 mA(1)(1)Determining Your PowerRequirements for a FixedControllerThe analog modules do not supply loop power forthe input device.

Whenthe NO4I module is used in a fixed controller, youmust provide an external power supply.When the NO4I or NO4V is used with an external 24V dc powersupply and is placed in a fixed controller expansion chassis, it iscompatible with those modules noted in the compatibility chartstarting on the previous page. When set for external power, themodule will only draw the 5V current off the backplane. Refer to thenext section for details on how to configure your module for externalpower.The 24V dc user power connection on a fixed SLC 500 can power anNO4I or NO4V analog module. However, the regulation of the 24V dcuser connection on a modular SLC 500 power supply, Catalog Number1746-P1, -P2, and -P4 is outside of the requirements of the NO4I andNO4V analog m
