E5EAA HENF105240R1工业模块ABB

使用梯形逻辑。在斜坡模式下，%AQ数据的变化会导致相应的输出通道斜坡至新的%AQ值。斜坡输出由每毫秒采取的步骤组成，直到达到终值。可为所有输入通道设置高报警限值和低报警限值，并向CPU报告每个输出通道的开路故障（电流输出模式）。根据扫描时间，所有六个模拟通道可在每次扫描时更新。表12-1。IC693ALG442模拟输出规格输出通道数量2，单端更新率4毫秒（近似值-两个通道）模拟电流输出电流范围0至20 mA 4至20 mA分辨率0至20毫安0.625µA（1 LSB=0.625µB）4至20毫安0.5µA（2 LSB=0.5µA）精度1所有电流模式25°C（77°F）时满量程的±0.1%，25°C（77°F）时满量程的典型±0.25%，（大）工作温度范围内满量程的±0.5%（大）大符合电压VUSER–3V（小）至VUSER（大）用户负载0至850Ωusing ladder logic. In ramp mode, changes in %AQ data cause the corresponding output channel to ramp to the new %AQ value. The ramp output consists of steps taken each millisecond until the final value is reached. High and low alarm limits can be set for all input channels and an open-wire fault (current output modes) is reported to the CPU for each output channel. All six analog channels may be updated on every scan, depending on the scan time. Table 12-1.
