Description

ABB BC820K01 3BSE071501R1 CEX-Bus Interconnection Unit

Overview

ABB BC820K01 3BSE071501R1 CEX bus interconnection unit is the communication module of ABB 800xA control system. It can establish communication connection, connect various devices, expand communication ports, increase the number of interfaces, and support redundant communication interfaces. It can divide the CEX bus into two independent network segments, and the maximum length of each segment is 200 meters, providing sufficient distance.

🚀Function & Features

BC820K01 divides CEX-Bus into two independent segments (maximum distance 200 meters), extending RCU-Link and CEX-Bus cables to 200 meters.

BC820K01 is compatible with PM858, PM862, PM866 (PR.F and above) and PM866A controllers.

BC820K01 is a dual redundant communication interface, a single device supports up to 6 CEX-Bus interfaces.

Fiber connection: Use LC duplex OM3 fiber to establish RCU data link

Copper cable connection: Use RJ45 crossover cable to connect control link
