1 PCS USED ABB Communication Board 3BHE027632R0101 #LYQ007
Part Number: 3BHE027632R0101; Product Name: Industrial Serial Communication Board
Brand: ABB (ABB Group, a Global Leader in Power and Automation Technologies for Industrial Applications)
Product Status: Original New Unit; Product Category: Serial Communication Expansion Board, Specifically Designed for ABB Distributed Control Systems (DCS) and Industrial Control Panels
Core Application: Widely integrated into ABB DCS, industrial automation control systems, and frequency converter control panels. It enables reliable data transmission between central controllers, remote I/O modules, and field devices in harsh industrial environments such as power plants, chemical processing facilities, and manufacturing workshops. Ideal for bridging communication gaps in critical control loops requiring stable serial signal exchange.
Core Features: Dual serial communication ports for multi-device connection; Strong anti-electromagnetic interference (EMI) performance; Wide compatibility with ABB native control systems; Compact design for cabinet-mounted installation; Built-in fault detection and signal monitoring functions; Optically isolated signal transmission for enhanced stability.
