The ABB BC810K01 and BC810K02 are CEX-Bus Interconnection Units used within the ABB AC 800M control system. They are essential for extending the CEX-Bus, which is the internal communication bus within the AC 800M system. While they serve the same fundamental purpose, they are offered as different kits with varying components.   

Product Name:

ABB BC810K01/BC810K02 CEX-Bus Interconnection Unit

Product Description:

• These modules are used to extend the CEX-Bus, allowing for greater physical distribution of I/O modules and other AC 800M components.
• The CEX-Bus is a high-speed, robust communication bus that connects the CPU, communication modules, and I/O modules within an AC 800M system.
• By using interconnection units, you can increase the number of I/O modules that can be connected to a single CPU and create more complex and distributed control systems.

Key Differences between BC810K01 and BC810K02:

The main difference lies in the contents of the kits:

• BC810K01: Typically includes one BC810 interconnection unit, one baseplate (TP857), and one interconnection cable (TK851).
• BC810K02: Typically includes two BC810 interconnection units, two baseplates (TP857), one interconnection cable (TK851), and two CEX-Bus terminators (TB850).  
• Essentially, the BC810K02 provides components for a redundant setup or for connecting to two separate CEX-Bus segments.

Product Parameters and Specifications (for the BC810 unit itself):

• Function: CEX-Bus extension
• Power Supply: Supplied via the CEX-Bus
• Connectors: Connectors for CEX-Bus in/out and interconnection cable  
• Baseplate: Requires a TP857 baseplate for mounting  
• Compatibility: Compatible with various AC 800M CPUs (e.g., PM857, PM861A, PM862, PM864A, PM865, PM866, PM866A, PM867, PM891)  

Product Use:

The BC810K01/K02 is used to:

• Extend the CEX-Bus: This allows for more I/O modules to be connected to a single AC 800M CPU than would be possible with a single CEX-Bus segment.  
• Create distributed I/O systems: By extending the CEX-Bus, I/O modules can be placed further away from the CPU, reducing wiring costs and complexity.
• Implement redundant CEX-Bus configurations: The BC810K02, with its dual units and terminators, facilitates redundant CEX-Bus setups for increased system availability.  

Applications:

• Large-scale industrial automation systems
• Applications with distributed I/O requirements
• Systems requiring high availability and redundancy

Key Features and Benefits:

• Extends System Capabilities: Increases the number of connectable I/O modules.
• Enables Distributed I/O: Reduces wiring complexity and costs.
• Supports Redundancy: Improves system availability.
• Robust and Reliable: Designed for industrial environments.
