可以改变通道7和8的平滑时间常数；参见
板
将读取的输入通道的功能可通过以下方式定义
软件默认值显示在软件图中
数字输入电源：48V/
50mA；不是galv。与DCS隔离
电子学
如果输入由内部+48 V（X7:3和/或X7:4）连接提供
必须从DCS 500模块的X7:1和/或X7:2接地。在里面
默认条件接地与转换器的机架相同。
如果输入由任何外部电源提供（+48 V直流、115 V交流或230 V
AC）中性线/线必须连接到X7:1或X7:2。如果输入
应使用相同的电压电平进行控制，但使用两个不同的电压
可能具有两个不同接地电平的电源，一条中性线应
连接到X7:1，二个连接到X4:2。在这种情况下，将输入连接到X8:2的跳线Wx必须
被切断。
对于其他跳线Wx也需要相同的方法。
高频接地由100nF电容器完成。
6.3模拟输入/输出板SDCS-IOB-3
如本章开头所述，有
配置输入/输出的各种选项。
SDCS-IOB-3板由5个模拟电路组成
输入，3个模拟输出，电流隔离
脉冲编码器接口和电流源
温度测量装置。
如果使用这些板，则必须安装它们
在DCS模块外部。它们必须安装在
这样，导电支架与装置的接地连接良好。
X1:/X1:和X2:/X2:之间的电缆长度为area
Input resistance: see diagram.
Input smoothing time constant: see diagram.
Smoothing time constant of channel 7 and 8 can be changed; see layout of the
board.
The functionality of the input channels, which will be read, can be defined by
software; default values are shown within the software diagrams
Power supply for digital inputs: 48V /
50mA; not galv. isolated from the DCS
electronics!
If the inputs are supplied from the internal +48 V (X7:3 and/or X7:4) a connection
must be done from either X7:1 and/or X7:2 to ground of the DCS 500 modules. In
default condition ground is identical to the converter's frame.
If the inputs are supplied by any external source (+48 V DC, 115 V AC or 230 V
AC) the neutral line / - line must be connected to either X7:1 or X7:2. If the inputs
should be controlled with the same voltage level, but from two different voltage
sources, having probably two different ground levels, the first neutral line should
be connected to X7:1 and the second to X7:2. In this case the jumpers Wx connecting the inputs to X7:2, but controlled by the source, connected to X7:1, must
be cut off.
The same method is needed for the other jumpers Wx.
High frequency grounding is done by 100 nF capacitor.  
6.3 Analogue I/O board SDCS-IOB-3
As described at the beginning of the chapter, there are
various options for configuring the inputs/outputs.
The board SDCS-IOB-3 consists of the 5 analogue
inputs, 3 analogue outputs, the galvanical isolated
pulse encoder interface and a current source for
temperature measuring devices.
If these boards are in use, they have to be mounted
outside the DCS module. They must be mounted in a
way, that the conductive supports have a good connection to ground of the installation.
The cable length between X1:/X1: and X2:/X2: is
1.7 m and between X1:/X3: is 0.5 m because of EMC
1.7米和X1/X3之间：由于EMC，为0.5米
