ABB BC810K02 3BSE031155R1 DCS redundant bus communication module

Product Description

BC810K02 with material number 3BSE031155R1 is an official complete kit of ABB CEX-Bus bus segmentation and redundant interconnection unit, specially designed for ABB AC800M 

controller and 800xA distributed control system platformABB.

The core function is to split the single CEX extended bus into multiple independent physical segments, isolate bus faults within a single segment and avoid the failure of one communication 

expansion card leading to the collapse of the whole CEX bus network, greatly improving the overall availability of redundant communication architecture. It is used to expand the onboard 

communication ports of PM series main controllers (PM861A/PM862/PM864A/PM865/PM866/PM867), support redundant PROFIBUS DP, Modbus TCP and other communication interface 

modules access, realize seamless redundant switching of fieldbus links.

This complete set is a high-integrity hot-swap solution, supporting online CPU replacement and module live plugging without stopping the DCS control system. The kit includes 2pcs BC810 bus 

interconnection main units, 2pcs TP857 mounting baseplates, 1m TK851 interconnection cable and 2pcs TB850 CEX-Bus terminal resistors. The circuit board adopts three-proof conformal coating, 

standard DIN rail cabinet installation, widely used as key maintenance spare parts for thermal power units, petrochemical refining devices, offshore platforms, wind power and water treatment 

800xA DCS system redundant communication transformation and overhaul projects.

Key Features

Physical segmentation of CEX extended bus, fault isolation of independent bus segments, single communication card or cable failure will not affect the operation of other bus branches, 

fundamentally enhance DCS communication network fault tolerance.

Native support for redundant communication interface modules deployment, automatic seamless master-slave switching during bus link failure, zero data interruption for process control signals.

Complete high-integrity system design, built-in power voting diode, fuse overcurrent protection and reverse power supply anti-reverse connection circuit on the baseplate, stable power supply for 

bus logic board.

Full online maintainability, realize non-stop CPU replacement and module hot swap, avoid long-term system shutdown loss in continuous production process industries such as chemical industry 

and power plant.

Standard complete kit configuration, equipped with base, interconnection cable and terminal resistor, no additional accessories purchase required, convenient for on-site rapid assembly and redundant 

rack wiring.

Hardware-level bus signal driving and isolation circuit, strong anti-electromagnetic interference ability, adapt to harsh workshop environment with frequency converter and large motor harmonic

 interference.

Perfect matching with ABB Control Builder M configuration software, no special program modification needed after replacement, only simple bus segment parameter setting required.

Rugged industrial aluminum casing and wide temperature adaptive design, long-term stable 24/7 uninterrupted operation in high-temperature central control room and offshore salt fog corrosive 

environment.
