用于数据传输的Ovation系统的数字I/O电路不需要：
单个双绞线或屏蔽对导线。多导体电缆，其中
一根导线用作公共回路，并带有一个整体电缆屏蔽，即
足以用于大多数Ovation数字信号应用。
2-8.3.触点闭合信号注意事项
•输出（CCO）-这些电路通常不需要屏蔽。
•输入（CCI）-如果电缆中的净电流
为零。
1.对于CE标志认证系统，所有现场布线必须在以下入口点进行编织屏蔽和接地：

Grounding is set through jumpers within the Personality module (for AI-13 bit), or at the terminal See Section 3-6 for details on accessing these jumpers. The AI-14 bit module requires a jumper block of the module (for AI-14 bit). The default setting for the module (AI-13 bit) has the jumpers installed for local grounding. To configure for field grounding, the jumpers must be removed. wire to be installed for local grounding. See individual module sections for details. Noise Minimization Techniques R3-1150 (Rev 3) 2-12 2/03 Emerson Process Management Proprietary Class 2C 2-8. Common Input Considerations1 2-8.1. 4 to 20 mA Signal Considerations When sufficient separation from noise sources exists, this standard class of control signal does not require shielded cables. However, it is strongly recommended for surge protection. Use of twisted-pair cables is recommended. 2-8.2. Digital Signal Considerations The Ovation System’s digital I/O circuits used in data transmission do not require individual twisted or shielded pair conductors. A multi-conductor cable, in which one conductor serves as a common return and with a single overall cable shield, is sufficient for most Ovation digital signal applications. 2-8.3. Contact Closure Signal Considerations • Outputs (CCO) - These circuits usually require no shielding. • Inputs (CCI) - These circuits require no shielding if the net current in the cable is zero. 1. For CE Mark certified systems, all field wiring must be braid-shielded and grounded at the entry point of the cabinet using the recommended hardware. Refer to “Cable Guidelines” in “Planning and Installing Your Ovation System”U3-1000 for FDDI and U3-1005 for Fast Ethernet. 2/03 3-1 R3-1150 (Rev 3) Emerson Process Management Proprietary Class 2C Section 3.
