Product Manual Excerpt

Analog Voltage Input - 16 Channel IC693ALG222 The 16-Channel Analog Voltage Input module provides up to 16 single-ended or eight differential input channels, each capable of converting an analog input signal to a digital value for use as required by your application. This module provides two input ranges: 0 to 10 V (unipolar) 10 to +10 V (bipolar) Voltage Ranges and Input Modes The default input mode and range is single-ended, unipolar, with the user data scaled so that 0 volts corresponds to a count of 0 and 10 volts corresponds to a count of +32000. The other range and mode are selected by changing the configuration parameters using the Logicmaster 90-30/20/Micro or CIMPLICITY Control configurator software, or the Hand-Held Programmer. The range can be configured for bipolar 10 to +10 V where 10 V corresponds to a count of 32000, 0 V corresponds to a count of 0, and +10 V corresponds to a count of +32000. High and Low alarm limits are available on all ranges. Ranges can be configured on a per channel basis. Power Requirements and LEDs This module consumes a maximum of 112 mA from the 5V bus on the PLC backplane. It also requires a maximum of 41 mA from the backplane Isolated+24 Volt DC supply to power the on-board power converter that provides isolated 5V supplies to power the user-side circuitry (see Table 3-9, Specifications). There are two green LED indicators on the module which provide module and user supply status. The top LED, MODULE OK provides module status information on power-up as follows: ON: status is OK, module configured OFF: no backplane power or software not running (watchdog timer timed out) Continuous rapid flashing: configuration data not received from CPU Slow flashes, then OFF: failed power-up diagnostics or encountered code execution error The bottom LED, Power Supply OK, indicates that the internally generated user-side +5V supply is above a minimum designated level. Location in System This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system. References Used The number of 16-Channel Analog Voltage Input modules which may be installed in a system depends on the amount of %AI and %I references available. Each module uses 1 to 16 %AI references (depending on the number of channels enabled) and from 8 to 40 %I references (depending on alarm status configuration). The available %AI references are: 64 with CPUs 311, 313, and 323; 128 with CPU331; 1024 with CPUs 340 and 341; and 2048 with CPUs 350 364. 10 10-10 Series 90-30 PLC I/O Module Specifications July 2000 GFK-0898F The maximum number of 16-Channel Analog Voltage Input modules which may be installed in a system are: 4 in a system using CPUs 311, 313, or 323 8 in a system using CPU331 12 in a system using CPUs 340 or 341 51 in a system using CPUs 350 364 When planning the module configuration for your application you must also consider the load capacity of the installed power supply and the total load requirements of all modules that are installed in the baseplate. Refer to the Series 90-30 Programmable Controller Installation Manual, GFK-0356 for details on power supplies and module load requirements. Table 10-3.

The summation of the differential input, common-mode voltage, and noise must not exceed 11 volts when referenced to COM. In the presence of severe RF interference (IEC 801-3, 10V/m), accuracy may be degraded to 5% FS. Analog Input Modules 10 GFK-0898F Chapter 10 Analog Input Modules 10-11 CPU Interface to the IC693ALG 222 Analog Voltage Input Module The Series 90-30 PLC uses the data within the %AI data table to record analog values for use by the programmable controller. This scheme for the 16-Channel Analog Voltage Input module is shown below. More information on the CPU interface to analog modules can be found at the beginning of this chapter.

A version of the 12 bits is placed within the 16-bit data word corresponding to the analog point (in the %AI table). The Series 90-30 PLC system handles the integration differently for the various analog modules. The CPU does not manipulate the data from the input modules before placing it within the word in the %AI data table. The bits in the %AI data table which were not used in the conversion by the input module are either forced to 0 (zero) by the analog input module. Placement of the 12 data bits from the A/D converter for an analog current input data word for the 16-Channel Analog Voltage Input module in unipolar range is shown below. X D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 X X X MSB LSB X=not converted bits Analog values are scaled over the range of the converter. Factory calibration adjusts the analog value per bit (resolution) to a multiple of full scale (that is, 2.5 mV/bit for unipolar; 5 mV/bit for bipolar). This calibration leaves a normal 12-bit converter with 4000 counts (normally 212 = 4096 counts). The data is then scaled with the 4000 counts over the analog range. For example, the data to the A/D converter for the 16-Channel Analog Voltage Input is scaled as shown below. 10 10-12 Series 90-30 PLC I/O Module Specifications July 2000 GFK-0898F A/D BITS (decimal) VOLTAGE; 0 to 10V RANGE a45717 0 10 0 4000 Figure 10-10.
