Technical Specifications

Features

➟System Integration for DCS: The DSBB170AM serves as a dedicated backplane for ABB's legacy DCS platforms (MP200/AC400). It provides the mechanical and electrical backbone for mounting CPU, communication, and I/O modules, ensuring seamless physical and signal integration .

➟High-Speed Data Communication: Engineered to handle the data traffic within the controller chassis, it allows for fast and deterministic exchange of process data between the central processor and field I/O signals .

➟Internal Power Distribution: In addition to data transfer, the board distributes operating power from the power supply unit to the various modules plugged into the chassis, simplifying internal wiring .

➟Industrial-Grade Construction: Designed for reliability in industrial environments, the PCB and connectors are built to withstand the electrical and mechanical demands of 24/7 process control applications, such as those in energy and chemical plants .

FAQ

➪ Q1: What is ABB known for in the industrial automation industry?

A1: ABB (ASEA Brown Boveri) is a global leader in power and automation technologies . The company is renowned for its comprehensive portfolio of industrial drives (ACS series), robotics, distributed control systems (800xA), and PLC systems (AC500). ABB products are widely used across power generation, oil and gas, chemical manufacturing, mining, and heavy industry applications .

➪ Q2: Are ABB products compatible with each other across different series?

A2: Generally, yes. ABB designs its products with backward and cross-series compatibility in mind. For example, the KVC758A board is specifically designed for ACS5000 drives but is also compatible with ACS800 and ACS880 cabinets . Similarly, ABB's Advant OCS 800xA DCS systems integrate with various ABB drive platforms, allowing for seamless system expansion and upgrades .
