Basic Product Identification
Model & Article Number: Model BC810K02, corresponding article number 3BSE031155R1
(compatible with 3BSE038692R1).
Product Category: CEX-Bus Interconnection Unit kit, part of ABB’s Ability™ System 800xA® platform,
designed to enhance the availability and redundancy of the CEX-Bus in AC 800M controller systems.
Kit Composition: An integrated package containing 2 BC810 interconnection units, 2 TP857
baseplates (width 60 mm), 1 TK851 interconnection cable (length 1.0 m), and 2 TB850 CEX-Bus
terminators.
Core Functional Characteristics
CEX-Bus Segmentation: Divides the CEX-Bus into separate segments to improve system availability,
especially for setups with redundant communication interfaces. Isolating segments prevents faults in
one segment from affecting the entire bus.
Redundancy Support: Enables redundant communication interface units on the CEX-Bus and works
with primary/backup CPU pairs (PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A,
PM867, PM891) to form fully redundant systems.
Hot Swap & Online Replacement: Supports hot swap functionality and allows online replacement of
the CPU baseplate without disrupting CEX-Bus traffic (note: replacing the BC810 itself stops traffic to
the connected CEX segment).
Hardware Structure: Each BC810 unit consists of a TP857 baseplate (with CEX-Bus connectors, external
power interface, voting diode, and fuse) and a power supply/logic board (integrating +3.3 V
converter, drive logic for CEX-Bus interconnection, and interconnection cable connector). The
baseplate is grounded to the DIN rail via metal housing parts.
Technical Specifications
Power Supply: Operates on 24 V DC nominal input (voltage range 19.2–30 V DC), with typical/max
power consumption of 50/70 mA and typical power dissipation of 1.2 W.
Mechanical Dimensions: Individual unit width 59 mm (2.9 in.), height 185 mm (7.3 in.), depth 127.5
mm (5.0 in.); total kit weight (including baseplates and accessories) 1.5 kg (3.31 lbs.).
Compatibility: Specifically designed for use with ABB AC 800M series CPUs
(PM857/PM861A/PM862/PM863/PM864A/PM865/PM866/PM866A/PM867/PM891), ensuring
seamless integration into existing 800xA systems.
Environmental Adaptability
Temperature Range: Operating 0–+55 °C (+32–+131 °F); storage -40–+70 °C (-40–+158 °F).
Humidity & Protection: 5–95% relative humidity (non-condensing); protection class IP20 (per
EN60529/IEC 529), suitable for installation in control cabinets.
Durability: Complies with industrial environmental standards, adapting to typical factory conditions
with stable performance under non-condensing humidity and wide temperature variations.
