ABB EI803F 3BDH000017R1 10BaseT Ethernet Communication Module

EI803F 3BDH000017R1 is an Ethernet communication card for ABB AC800F controller under System 800xA Advant platform, manufactured in Germany. It follows IEEE802.3 10BaseT twisted-pair standard, acting as the network gateway to realize data interaction between the controller, engineering workstation, HMI and upper SCADA/MES systems, supporting TCP/IP, SNMP and native ABB control network protocols.

This single-slot rack module equips one RJ45 port with link/activity status LEDs, built-in 8MB RAM+8MB Flash for data cache. It supports redundant network deployment and complete self-diagnosis, compatible with Advant control rack structure. Widely stocked as spare replacement for thermal power, petrochemical legacy DCS cabinet communication fault maintenance and system network expansion projects.
