Manufacturer: Azbil Corporation
Model: HD-AOM100HC/ HD-HAM100HC

Summary 

HART communication compliant I/O modules (BU100H*) execute both 4–20 mA analog input/output processing functions for control loops and communication interface functions for communication with HART-compliant devices.
BU100H modules maintain full compatibility with existing analog input/output modules for base unit mounting type in module shape and I/O functions. As a result, they are easy to use in an Azbil DCS such as Advanced PS or Harmonas-DEO.
It is possible to introduce Azbil’s InnovativeField Organizer Device Management System, which provides various device management solutions, and also keep existing control loop functions using BH100H.

Features

1. Enables easy realization of a HART communication environment
Easy implementation of HART communication using existing 4–20 mA wiring, which is one of features of HART communication.
HART communication can be implemented by replacing existing Azbil controllers in the following systems with I/O modules.

Connectable Azbil Corporation controllers

2. Faster HART communication throughput
The one-by-one HART modem method allows faster communication throughput than the general HART multiplexer method, achieving 1200 bps full speed HART communication.

3. Reliable and safe design
Field-proven design is used for the 4–20 mA analog I/O control circuit. There is no need to worry about new I/O modules.
A HART communication failure will not affect control, because the HART circuit is completely separate from the 4–20 mA analog I/O circuit.
