IS200TRLYH1D系统模块卡件
每个alog能够提供四个范围（两个电压和两个电流）：0到+10伏（单极）-输入和s的默认范围。–10到+10伏特（双极）毫毫。每个alog都能够将15到16位（取决于所选范围）的biry（数字）数据转换为alog，以供您的应用程序使用。12 12-2系列90–30 PLC I/O模块规格–2000 GFK–0898F中的用户数据%AI和%AQ寄存器处于16位2的补码状态。在当前模式下，每个都会向报告开路故障。当系统电源中断时，模块可以进入kwn最后状态。只要向模块施加用户电源，每个模块都将保持其最后的数值，或重置为刻度（范围）的低端，具体取决于模块的配置方式。每个可配置为使用梯形逻辑以斜坡模式运行。在斜坡模式下，%AQ数据的变化导致相应的斜坡上升到新的%AQ值。斜坡由每毫秒采取的步骤组成，直到达到临界值。可以为所有输入设置高报警限值和低报警限值，并向每个输入报告开路故障（电流模式）。根据扫描时间，每次扫描都会更新所有六个对话框。表12-1。IC693ALG442 Alog规格数量2，单端更新率4毫秒满量程工作温度范围负载5（最小电阻2K欧姆）负载电容1µF（电容）Alog输入规格输入数量4，差分更新率8毫秒（约为所有4秒）Alog电流输入IC693ALG442 Alog Combination I/O模块12 GFK–0898F第12章–IC693ALGA442 AlogCombition I/O模块12-3输入范围增强（下一页续表）（上一页续）DC至1 kHz输入阻抗800K分辨率交叉抑制>80 dbΩ （典型）输入滤波器响应29 Hz电源要求外部电源电压范围20至30（典型24）电源抑制比（PSRR）4电流电压5µA/V（典型）、10µA/V 25/V（典型值）、50/V电压纹波10%来自Interl+5V电源95来自外部用户电源129 1在存在严重RF干扰（IEC 801-3，10V/m）的情况下，精度将降低到±1%FS。2如果存在严重的射频干扰（IEC 801-3，10V/m），精度将降低至±4%FS。3如果存在严重射频干扰（IEC801-3，10V/m），精度可能降低至±2%FS。4PSSR通过将VUSER从24V干燥到30V来测量。产品标准和一般规范参见附录B。12 12-4系列90–30 PLC I/O模块规格–2000 GFK–0898F IC693ALG442输入模式和电流/电压范围电流操作在该范围内，用户数据被缩放，从而4对应于计数0，20对应于计数32000。通过使用Logicster 90-30/20/Micro组态软件或手持式编程器更改组态参数来选择其他范围。在该范围内，用户数据被缩放，使得0对应于0的计数，20对应于32000的计数。全12位分辨率在该范围内可用。也可以选择增强范围。选择此范围时，0对应于–8000的计数，4对应于0（零）的计数，20对应于+32000的计数。增强型量程使用与量程相同的硬件，但自动提供量程缩放，但为4和0之间的输入电流电平向用户提供负数字值除外。这使您能够选择一个低报警限值，以检测输入电流何时从4降至0，从而在应用程序中提供开路故障检测。所有范围都有高报警限值和低报警限值。范围可以根据具体情况进行配置。
Each alog is capable of providing four ranges (two voltage and two current): 0 to +10 volts (unipolar) - default range for both input and s. –10 to +10 volts (bipolar) milli milli Each is capable of converting 15 to 16 bits (depending on the range selected) of biry (digital) data to an alog for use as required by your application. User data in 12 12-2 Series 90–30 PLC I/O Module Specifications – 2000 GFK–0898F the%AI and %AQ registers is in a 16-bit 2’s complement fort. In current modes, an open- fault is reported to the for each . The module can go to a kwn last state when system power is interrupted. As long as user power is applied to the module, each will intain its last lue, or reset to the low end of the scale (range), as determined by how you have configured the module. Each can be configured to operate in ramp mode using ladder logic. In ramp mode, changes in %AQ data cause the corresponding to ramp to the new %AQ lue. The ramp consists of steps taken each millisecond until the fil lue is reached. High and low alarm limits can be set for all input s and an open- fault (current modes) is reported to the for each . All six alog s y be updated on every scan, depending on the scan time. Table 12-1.

The other ranges are selected by changing the configuration parameters using the Logicster 90-30/20/Micro configurator software or the Hand-Held Programmer. In the range user data is scaled so that 0 corresponds to a count of 0 and 20 corresponds to a count of 32000. Full 12-bit resolution is ailable over the range. A Enhanced range can also be selected. When this range is selected, 0 corresponds to a count of –8000, 4 corresponds to a count of 0 (zero) and 20 corresponds to a count of +32000. The Enhanced range uses the same hardware as the range but autotically provides range scaling with the exception that negative digital lues are provided to the user for input current levels between 4 and 0 . This gives you the capability of selecting a low alarm limit that detects when the input current falls from 4 to 0 , which provides for open- fault detection in applications. High and Low alarm limits are ailable on all ranges. Ranges can be configured on a per basis.
