Description
Product Introduction & Engineering Value
Not every communication problem originates from the controller. In long-running ABB process automation systems, the fieldbus interface is frequently the component that determines whether remote I/O remains visible to the control network. The ABB CI810B provides the AF100 communication bridge between the S800 I/O system and higher-level ABB controllers.
Designed for AC 800M and System 800xA architectures using the AF100 network, the CI810B enables deterministic communication with distributed I/O while preserving existing plant infrastructure. For facilities extending the service life of legacy AF100 installations, replacing the communication interface is often considerably less disruptive than migrating to a different fieldbus.

Field Application & The “Trench” Experience
During a scheduled shutdown at a wastewater treatment facility, operators experienced intermittent loss of several remote S800 I/O stations connected through the network. Cable insulation tests and controller diagnostics showed no permanent wiring faults, yet communication continued to drop under load.
The maintenance team replaced the aging CI810B communication interface while leaving the controller program and field wiring unchanged. After restoring power, the network stabilized immediately, and the remote I/O stations returned to normal operation without additional configuration.
Typical applications include:
- Distributed S800 I/O networks in municipal water treatment plants
- Boiler control systems using AC 800M controllers
- Pulp and paper process automation with fieldbus communication
- CI810B
- CI810B
Transparency SOP: QA & Testing
Every module is processed through a documented inspection workflow before shipment.
- ✔ Verify ABB article number 3BSE020520R1
- ✔ Inspect PCB, connectors, and housing for physical damage
- ✔ Verify ModuleBus and connector integrity
- ✔ Perform power-up verification using compatible ABB hardware
- ✔ Confirm communication diagnostics and status indicators
- ✔ Package using anti-static protection and impact-resistant materials
Professionally refurbished modules also undergo functional communication testing before release.
The Veteran’s Tech Trap Guide
⚠️ is not PROFIBUS.
The is dedicated to Advant Fieldbus 100. Although several ABB communication modules share a similar appearance, they support entirely different fieldbus protocols. Verify the network architecture before ordering.
⚠️ Check the accessories before replacing the module.
The communication interface depends on the correct TB807 ModuleBus Terminator and associated connectors. Missing or damaged accessories can create intermittent communication faults that resemble module failures.
PRO TIP:
Before removing the existing , document the node configuration and inspect the twisted-pair cable shield termination. In older installations, degraded cable terminations are often responsible for unstable communication rather than the interface itself.
⚠️ Don’t ignore software revisions.
When replacing hardware in legacy System 800xA or AC 800M installations, verify that the controller software revision supports the installed communication interface to avoid unnecessary commissioning delays.
Dynamic FAQ
Q1. What is the primary function of the ABB ?
The provides communication between the S800 I/O system and the (Advant Fieldbus 100) network, enabling distributed process control within ABB automation systems.
Q2. Which ABB platforms support the ?
The module is used with S800 I/O, AC 800M, and System 800xA installations utilizing the fieldbus architecture. Compatibility should always be confirmed against the controller configuration.
Q3. What accessories are included with the ?
The standard package includes a Power Supply Connector, TB807 ModuleBus Terminator, two terminal blocks, and an connector, in addition to the communication module itself.
Q4. Are New Surplus modules genuine ABB products?
Yes. New Surplus inventory consists of unused original ABB products stored under controlled warehouse conditions. Each module is verified for identity, physical condition, and connector integrity before shipment.
Q5. Can the be replaced without modifying the control application?
In most cases, yes. Since the module serves as a communication interface, application logic usually remains unchanged. However, controller software compatibility and network configuration should always be verified before commissioning.
Q6. Is warranty available?
Yes. Both New Surplus and professionally refurbished modules are supplied with warranty coverage. Warranty duration depends on inventory condition and is confirmed with the quotation.
