8C-PAOHA1   HONEYWELL C300控制器 输入输出终端组件(IOTA)

本文档提供了配置Series 8 I/O的技术信息。以下系列8 I/O项目包括在本文档中。
•TC / RTD
•模拟输入-单端
•模拟输入HART -单端
•模拟输入HART -差分
•模拟输出
•模拟输出HART
•数字事件输入序列(SOE)
•数字输入，24 VDC
•数字输入脉冲积累
•数字输出，24 VDC
•DO继电器扩展板
定义
•输入输出终端组件(IOTA):用于保存IOM和现场接线连接的组件;
•输入输出模块(IOM):一种包含执行特定I/O功能所需的大多数电子设备的设备。IOM插到IOTA上。
特性
所有系列8组件都采用创新设计，支持增强的热管理。这种独特的外观显著减小了等效功能的总体尺寸。
系列8 I/O的独特功能包括:
•I/O模块和现场终端组合在同一区域。I/O模块插入IOTA，以消除对单独机箱容纳电子组件的需求
•两层“可拆卸”端子，用于将现场接线安装在外壳中，使设备安装和维护更容易。
•通过IOTA提供现场电源，无需额外的电源为现场设备和相关的工艺有线编组供电
•冗余直接在IOTA上完成，无需任何外部电缆或冗余控制设备，只需在IOTA上添加第二个IOM
•对于IOM和IOTA，提供涂层(模块编号以8C开头)和非涂层(模块编号以8U开头)选项。保形涂层材料应用于电子电路，作为防止潮湿，灰尘，化学品和极端温度的保护。当电子产品必须承受恶劣环境并需要额外保护时，建议使用涂层IOM和IOTA。

8C-PDILA1

This document provides technical information to configure the Series 8 I/O. The following Series 8 I/O items are included in this document.
• TC/RTD
• Analog Input – Single Ended
• Analog Input with HART – Single Ended
• Analog Input with HART – Differential
• Analog Output
• Analog Output with HART
• Digital Input Sequence of Events (SOE)
• Digital Input, 24 VDC
• Digital Input Pulse Accumulation
• Digital Output, 24 VDC
• DO Relay Extension Board
Definitions
• Input Output Termination Assembly (IOTA): An assembly that holds the IOM and the connections for field wiring;
• Input Output Module (IOM): A device that contains most of the electronics required to perform a specific I/O function. The IOM plugs onto the IOTA.
Features
All Series 8 components feature an innovative design that supports enhanced heat management. This unique look provides significant reduction in overall size for the equivalent function.
The unique features of Series 8 I/O include:
• I/O Module and field terminations are combined in the same area. The I/O Module is plugged into the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies
• Two level “detachable” terminals for landing the field wiring in the enclosure, providing easier plant installation and maintenance.
• Field power is supplied through the IOTA, with no need for extra power supplies to power the field devices and the associated craft wired marshalling
• Redundancy is accomplished directly on the IOTA without any external cabling or redundancy control devices, by simply adding a second IOM to an IOTA
• For both IOM and IOTA, coated (module numbers starting with 8C) and uncoated (module numbers starting with 8U) options are provided. Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and added protection is necessary.
