ABB CI610 3BHT30003R1 I/O Bus Extender for Basic Unit

The ABB CI610 (3BHT30003R1) is a purpose-built I/O Bus Extender used in ABB’s Advant Controller 31 and related automation platforms. It plays a critical role in expanding the I/O bus from the base unit to additional I/O stations when the number of required I/O modules exceeds the limits of a single basic unit.

Designed to support high-performance industrial control environments, the CI610 ensures data integrity, real-time responsiveness, and seamless communication across extended I/O chains. This expansion capability is essential in modern automation where scalability, modularity, and future-proof design are key requirements.

The CI610’s compact construction, rugged reliability, and easy DIN rail mounting make it a standard in many industrial setups that require extended I/O configurations without compromising system performance.

Technical Specifications

Applications

The CI610 I/O Bus Extender is used in a wide range of industries and system architectures where flexible expansion of I/O is a necessity. Typical application fields include:

• Process Control in Chemical and Petrochemical Plants

• Water and Wastewater Treatment Facilities

• Food and Beverage Processing

• Tool-Free DIN Rail Mounting: Speeds up installation, especially in field conditions.

• Zero External Power Requirement: Power drawn from the bus simplifies electrical planning.

• ABB Compatibility Assurance: Fully verified for use with ABB Advant systems, minimizing integration risk.

• Long Lifecycle Support: Designed for long-term availability and support under ABB’s industrial lifecycle management programs.

Frequently Asked Questions (FAQ)

1. What exactly does the CI610 do in an automation system?

The CI610 extends the I/O bus from a basic unit, allowing additional I/O modules to be connected for system expansion.

2. Is this module hot-swappable?

No, it should be installed or removed only when the system is powered down to avoid data corruption or hardware damage.

3. Does CI610 support redundant configurations?

Yes, when designed appropriately, CI610 can be part of redundant I/O structures to ensure high availability.

4. How many I/O modules can I connect after a CI610?

This depends on the total power and signal limitations of the host system. Refer to ABB’s design manuals for exact limits.

5. What kind of communication protocol does CI610 use?

It uses ABB’s proprietary high-speed serial bus protocol for internal communication.

6. How do I install the CI610 in my system?

It is DIN rail mountable and plugs into the system via pre-configured bus connectors.

7. Can I use CI610 with non-ABB systems?

No, CI610 is designed specifically for use with ABB automation platforms like Advant Controller 31.

8. Does the CI610 generate any heat?

Minimal heat is generated due to its low power consumption and passive cooling design.

9. Is firmware update required for CI610?

No firmware is required. CI610 functions as a passive hardware extension without a programmable interface.

10. What certifications does this module meet?

The module complies with CE, RoHS, and relevant IEC standards for industrial environments.
