Compatible Replacement & Equivalent Models
When the CI853K01 is unavailable or end-of-life, the following modules may serve as functional replacements depending on your system configuration. Always verify firmware and backplane compatibility before substitution.
- ABB CI854K01 (3BSE025255R1) – PROFIBUS DP interface; suitable if migrating to PROFIBUS topology
- ABB CI855K01 (3BSE018106R1) – RS-485 / RS-232 combo interface; drop-in for single-port RS232 applications
- ABB CI856K01 (3BSE018107R1) – Ethernet TCP/IP interface; recommended for modernization projects
- ABB CI858K01 (3BSE018174R1) – FOUNDATION Fieldbus H1 interface; for FF-based field devices
- Third-party serial gateways – Moxa NPort or Advantech EKI series can bridge RS232 to Ethernet when full module replacement is not feasible
Note: Konmask.com recommends using original ABB modules for safety-critical applications. Contact our team for compatibility verification.

Selection Guide
Use the table below to select the correct ABB communication interface for your application:
- Need RS232-C serial (2 ports) → CI853K01 ✅ (this module)
- Need RS485 / RS232 (1 port each) → CI855K01
- Need PROFIBUS DP master → CI854K01
- Need Ethernet TCP/IP → CI856K01
- Need FOUNDATION Fieldbus H1 → CI858K01
- Need DeviceNet → CI867K01
- Need Modbus TCP (Ethernet) → CI856K01 + Modbus TCP configuration
If your application requires connecting two independent Modbus RTU serial loops to a single AC 800M controller, the CI853K01 is the optimal choice.

Replacement & Compatibility FAQ
Q: Can CI853K01 be used as a drop-in replacement for CI855K01?
A: Not directly. CI853K01 provides two RS232-C ports; CI855K01 provides one RS232 and one RS485. Wiring and software configuration must be adjusted.
Q: Is CI853K01 compatible with AC 800F controllers?
A: No. CI853K01 is designed exclusively for the AC 800M platform with S800 I/O ModuleBus backplane.
Q: Can I use a third-party RS232-to-Ethernet gateway instead?
A: Yes, for non-safety applications. Moxa NPort 5000 series is commonly used. However, native ABB modules provide better diagnostics and deterministic performance.
Q: What is the lead time for CI853K01?
A: In-stock units ship within 3–5 business days. For sourced units, typical lead time is 2–4 weeks. Contact us for current availability.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all modules. Extended warranty options are available upon request.
