DATX110通讯模块,DATX110如何使用
所有现场控制输入/输出模块的输入/输出设备都需要现场侧电源。电源设备
在具有类似电源要求的模块之间，DATX110可以轻松地“菊花链”连接。
任何一个螺钉上都有10安培的最大限值。或者，可以使用单独的电源
在任何模块组合上，根据需要提供隔离。
输入/输出模块上电源连接的位置取决于模块类型。对于
有关特定类型模块电源连接的信息，请参阅其单个模块
数据表。
热插拔电源线
对于热插入/移除模块，必须关闭要插入的模块的电源，或
远离的。安装过程中应提供断开模块电源的方法。
噪声抗扰度
良好的布线实践是可靠和可预测系统运行的基础。
DATX110通讯模块,DATX110如何使用
应使用第1章中列出的电气环境标准作为基准。不受控制的
实际装置中的组合效应、较高级别的噪声或具有不同噪声源的噪声
标准中的属性仍可能导致问题。因此，必须遵循
安装中的谨慎布线和抑制实践。
设备外部和电缆槽中的接线应按照公认的做法进行分离。
All Field Control I/O modules require field-side power for their I/O devices. Power supply
connections can easily be “daisy-chained” between modules with similar power requirements.
There is a 10 Amp maximum limit on any one screw. Alternatively, separate supplies can be used
on any combination of modules to provide isolation as needed.
The location of the power connection on an I/O module depends on the module type. For
information on power connection to a specific type of module, refer to its individual module
datasheet.
Power Wiring for Hot Insertion/Removal
For Hot Insertion/Removal of modules, power must be switched off to the module being inserted or
removed. A means of removing power to the module should be provided during installation.
Noise Immunity
Good wiring practices are the foundation for reliable and predictable system operation.
The electrical environmental standards listed in chapter 1 should be used as benchmarks. Uncontrolled
combinational effects in a real installation, higher levels of noise, or sources of noise with different
properties from those in the Standard can still cause problems. Therefore, it is important to follow
prudent wiring and suppression practices in the installation.
Wiring external to equipment and in cable trays should be separated following accepted practices.
