ABB G3ENa HENF450268R2数字量输入卡件

产品详细资料
由于输入多路复用器的低通道输入由模拟输入和自测试多路复用器信号共享，相应的输入通道也通过自测试多路器进行路由，所有活动组件都以“回送”方式运行。控制处理器可以通过向特定输出通道发送电压电平代码，然后验证ADC在对信号采样后产生相同的代码，以在线或离线模式执行环回测试。该技术在第4节自检标准中有详细描述。车载标定测试电压参考可跳线配置为标称±2.5 VDC、±5.0 VDC或±10 VDC（实际电压略低于这些电压，以确保自检和自动校准期间的范围内转换）。
Because the low channel inputs of the input multiplexers are shared by both the analog inputs and the self-test multiplexer signal, the corresponding input channels also are routed through the self-test multiplexer.Loopback Testing of Inputs and Outputs By routing, the analog outputs through the analog input multiplexers (see previous section), all active components are exercised in a "loopback" arrangement. The controlling processor can perform a loopback test in either the on-line or off-line mode by sending a voltage-level code to a specific output channel, and by then verifying that the ADC produces the same code after sampling the signal. This technique is described in detail in Section 4.Self-Test Standards The on-board CAL TEST VOLTAGE REFERENCE is jumper-configurable to one of the following levels as nominally ±2.5 VDC, ±5.0 VDC, or ±10 VDC (actual voltages are slightly less than these in order to ensure in-range conversions during self-test and autocalibration).
