Yokogawa Analog I/O Module AAI135-H50/13A00

GENERAL

Yokogawa Analog I/O Module AAI135-H50/13A00
This document describes about hardware specifications of Yokogawa Analog I/O Module AAI135-H50/13A00 to be installed in the ESB bus node units (ANB10S and ANB10D), Optical ESB bus node units (ANB11S and ANB11D), and field control units (for FIO) (AFV30S, AFV30D, AFV40S, AFV40D, AFV10S, AFV10D).
TheseYokogawa Analog I/O Module AAI135-H50/13A00 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.

HART Communication Functional Specifications

Yokogawa Analog I/O Module AAI135-H50/13A00

The analog I/O modules (with HART communication function) are equipped with HART modems and eable HART
communication (*1) by directly connecting the HART devices to he modules.
No. of HART devices: Max. 16 devices/module
HART variables:  Max. 32 points/module
HART variables can be treated as ordinary process input data via %Z terminal connection. It is just for input.
HART multidrop connection (*2):  Max. 5 devices/channel
HART variables data refresh cycle time :
1 second/device (When maximum of 16 devices are connected, it is 17 seconds per ESB bus connection.)

*1: HART communication refers to HART variable communicaiton, on-demand communication, and hand held terminal (HHT)
communication.
*2: It is possible to connect only input devices. This connection does not support analog data value nor burst function.
