AAI143-H50/A4S00 AAI143-H50 模拟输入模块

This document describes about hardware specifications of Analog I/O Modules (for FIO) to be installed in the ESB bus node units (ANB10S and ANB10D), Optical ESB bus node units (ANB11S and ANB11D), ER bus node units (ANR10S and ANR10D) (*1), and field control units (for FIO) (AFV30S, AFV30D, AFV40S, AFV40D, AFV10S, AFV10D, AFF50S, and AFF50D).
These analog I/O modules function as signal converters; by inputting field analog signals into these modules, it converts them to internal data for field control stations (FCS), or the FCS’s internal data to analog signals for outputs.

These modules provide 16 inputs of mainly 4 to 20 mA DC or 1 to 5 V DC standardized signals from 2-wire/4-wire transmitters.
They can be used in dual-redundant configuration.

This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.

*1: A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in intrinsically safe application.
*2: The module input resistance viewed from the terminals depends on the current strength as calculated as below:

*3: This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.
*4: This module can be used only with the following FCSs – AFG30, AFG40, AFG8, AFF50, AFV10, AFV30, or AFV40.
*5: Input mode for each channel is selectable by software.
*6: The module input resistance viewed from the terminals depends on the current strength as calculated as below:

*1: A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in intrinsically safe application.
*2: The module input resistance viewed from the terminals depends on the current strength as calculated as below: 250 Ω + current value voltage drop in the input protection circuit F03E.ai
*3: When this module is used in the ambient temperature of 60 to 70 ºC by being installed in a node unit that conforms to the temperature environment, the allowable load resistance is 200 to 750 Ω.
*4: This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.
*5: A Zener barrier is not allowed to be connected with this module for current output. Use an isolation barrier when the module is used in intrinsically safe application.
*6: A Zener barrier is not allowed to be connected with this module for current input. Use an isolation barrier when the module is used in intrinsically safe application. And this module can be used only with the following FCSs – AFG30, AFG40, AFG8, AFF50, AFV10, AFV30, or AFV40.
*7: Input mode for each channel is selectable by software.
*8: When this module is installed to a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
