Description
1. Product Overview
The ABB BC810 is a specialized Interconnection Unit designed for the S800 I/O distributed system. Its primary role is to extend the ModuleBus communication from a controller (like the AC 800M) to multiple I/O clusters or to connect different parts of an I/O station over a distance.
The BC810 acts as a bridge, ensuring that data signals remain strong and synchronized across extended distances or complex cabinet layouts. By using the BC810, engineers can design more flexible control architectures, allowing I/O modules to be placed closer to the field sensors while maintaining high-speed communication with the central processing unit.
Key Applications:
- I/O Cluster Expansion: Connecting additional I/O modules when a single rack is full.
- Distributed Control Layouts: Bridging ModuleBus signals between different cabinets.
- System Scalability: Allowing for the seamless addition of S800 I/O clusters to an existing AC 800M system.
- Signal Strengthening: Ensuring signal integrity in large-scale industrial I/O configurations.

7. FAQ
Q: What is the difference between BC810 and BC820?
The BC810 is for single (non-redundant) ModuleBus interconnection, while the BC820 is designed for redundant ModuleBus applications, often used in high-availability systems where dual controllers are employed.
Q: Does the BC810 require a specific termination unit?
Yes, the BC810 is typically mounted on a termination unit like the TU810 or similar models that provide the physical connections for the ModuleBus cable.
Q: Can I use the BC810 to connect I/O modules over a distance of 10 meters?
The ModuleBus has specific distance limitations. For distances beyond a few meters, you may need to use fiber optic extensions or specialized communication interfaces (like CI801 for PROFIBUS) instead of a simple BC810 interconnection.
