– 0 32000 2000 rpm – 0 rpm = Solving the above equation, scaling an input in a program: Xrpm = %AI 16. scaling an in a program as: %AQ = Xrpm x 16. Ather example would be a 1 to 5 volt sigl which actually represents . If you want to use lues in your program that are actually lues, use the following equation for calculating scaling factors. Data Word X – 4 32000 20 – 4 = Solving the above equation, scaling an input in a program: X = (%AI 2000) + 4 scaling an in a the placement and scaling kwn, you can modify the data from the %AI table or the data to the %AQ table by the scale factor to satisfy your application needs. Perfornce Measures The perfornce of alog modules can be measured by resolution, accuracy, linearity, and cross- rejection. Resolution of the module is the weight assigned to the least significant bit in the conversion process. For example, 4 µA/bit is the resolution of the alog current module. A module with 8 µA/bit has half the resolution of the alog current module. The resolution of a module is determined by the converter used in the alog module. The accuracy of the module is dependent upon the tolerances of components used in the module’s ry. Accuracy is the difference between the expected and measured lues. Linearity is the difference between the measured change and the ideal one LSB change between any two adjacent s. Cross- rejection is the influence on one when the input to ather is changed. General Alog Module Infortion 9 GFK–0898F Chapter 9 – General Alog Module Infortion 9-11 Alog Module Field Wiring Connections to an alog module from user field devices are de to screw termils on a remoble 20-termil connector block mounted on the front of the module. Infortion on field wiring for alog modules can be found in two basic places in this nual: Chapter 2, “General Installation Guidelines.” Contains such infortion as mounting, wiring, and ise suppression methods. Details specific to individual modules, such as termil pin–out infortion, are shown in the alog module data sheets, which are found in Chapters 10, 11, and 12. 9 9-12 Series 90–30 PLC I/O Module Specifications – 2000 GFK–0898F Number of Alog Modules per System The number of modules installed in a system depends on several factors, including ailable references for each model, current consumption for each module to be installed, slots ailable in baseplate(s), selectable configuration parameters and, where applicable, whether Isolated +24 is supplied by the PLC backplane or by a user provided supply. Before installing modules in a baseplate, verify that the total current consumption of all of those modules does t exceed the power rating of the Series 90-30 power supply (30 , all voltages). The following tables will help you determine the number of alog I/O modules that can be installed in a Series 90-30 PLC system. Calculations assume number of references used. Modules with selectable references can have more modules per system. Table 9-3. User Reference and Current Requirements Alog Module %AI References %AQ References %I References Current from +5 Current from Isolated +24 IC693ALG220 For all supplies – total power for all s cant exceed 30 . Supplied from Isolated +24 on backplane, or from user supply. Table 9-4.
