ABB H&B Contronic HW 81 Module HW 81 H&B Contronic

ABB H&B Contronic HW 81 Module HW 81 H&B Contronic

The ABB H&B Contronic HW 81 Module is a specific module in the H&B Contronic range from ABB, the details of which are given below:

Model number and identification: The module has the model number 0776217a and is clearly identified in the H&B Contronic system as HW 81.

Functional characteristics: Although there is no explicitly disclosed detailed functional description, as an integral part of the Contronic system, it usually undertakes specific tasks in the industrial automation control process, which may involve signal processing, data acquisition, transmission and execution of control commands, etc., in order to ensure the stable operation and efficient control of the entire control system.

Application areas: Mainly used in industrial automation, commonly used in various types of industrial production processes that require precise control and monitoring, such as chemical, electric power, metallurgy, pharmaceutical and other industries, to help achieve the automation of the production process, intelligent and efficient management.

Product status: According to Classic Automation website information, the number of its stock is 1, from the side to reflect this product may be due to technological updates or changes in market demand, etc., in the current market supply is relatively small, but there is still a certain market demand exists, especially for some of the use of older models of the ABB control system and the need for maintenance and replacement of the module of the enterprise.

FEATURES

• Process Station with integrated fieldbus  capability  

• 4 high-speed fieldbus lines  

• Supports different fieldbus types, even  simultaneously:  PROFIBUS-DP, up to 12 MBd  Modbus  CAN  Foundation Fieldbus H1 (with LD800  HSE)  

• Easy engineering:  fully integrated in Control Builder F  

• One unified database for field devices  shared by the control level and the Human  System Interface (HSI)  

• Module recognition with factory and operational parameters  

• Comprehensive diagnostics for proactive  maintenance  

• Compact, rugged design  

• Front panel connectors  

• DIN Rail (C-rail) or wall mounting for easy  installation  

• Ambient temperature 0-60 °C (32-140 °F)  with temperature monitoring  

• EMC certification according to EN50082  

• Certification:  CE, NAMUR, CSA, UL, EN61000-6-2.

The AC 800F is available in two versions:  

• 4 MB static RAM, 4 MB EPROM  

• 16 MB synchronous dynamic RAM,   8 MB EPROM

The AC 800F optionally provides several levels  of redundancy: 

• device redundancy with 2 AC 800F  

• power supply redundancy (24 V DC)  

• Ethernet communication redundancy   (standard)  

• Cable redundancy for Profibus DP,   requires external equipment (RLM01)

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.
