Product Overview

• PN: YPK112A
• Alternative part code: 3ASD573001A133
• Brand: ABB
• Series: Advant and legacy 800xA automation control system
• Type: Fieldbus Communication Module

• Function: It is the core gateway communication board for ABB early Advant control system. It works as a signal bridge between APC advanced process control station and Advant Fieldbus 100 fieldbus. It conducts two-way transmission of real-time process parameters, control commands and equipment fault data, finishes protocol conversion and data forwarding between upper control layer and field I/O devices, and guarantees steady data interaction of the entire distributed control system.

Core Features

• Galvanic isolation circuit between bus and control side, isolation voltage reaches 2500VAC to eliminate ground loop interference
• Supports proprietary Advant Fieldbus 100 protocol with maximum transmission speed 1Mbps
• Equipped with BNC coaxial bus port and backplane pin connector, stable connection and anti-vibration performance
• Onboard LED indicators to show power status, bus communication state and module faults clearly
• PCB with conformal coating for dustproof, moistureproof and anti-corrosion performance, suitable for long term operation in industrial control rooms
• Standard plug-in card design, allows hot swap under redundant rack power supply without system shutdown

• Built-in short circuit and overvoltage protection to prevent backflow damage to main control backplane
