YOKOGAWA PLC MODULE AAI841-H03 AAI841-H00 AAI835-S50 AAI835-H03 AAI835-H00 AAI543-S53 AAI543-S50 Analog I/O Module
The Yokogawa AAI841 analog I/O module (with HART communication function) connected to a transmitter or a valve positioner receives HART variable (*1) in addition to exchange analog input/output data by 4 - 20 mA signal with field control stations (FCS). There are 8 types of analog I/O modules (with HART communication function).
HART Communication Functional Specifications
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 and 19 seconds for ER bus connection.) Analog data refresh cycle time (*3): The number of ER bus node unit determines the analog data refresh cycle time in between the ER bus master interface module (EB401) and ER bus node units. With HART communication, it takes twice as much time than without HART comunication
