Description
1. Product Description
The CI858K01 is a high-performance communication interface module designed for ABB’s AC800M PLC system, enabling seamless integration of field devices via Profibus-DP protocol. As part of ABB’s modular automation portfolio, the CI858K01 serves as a critical bridge between PLC controllers and distributed I/O systems (e.g., S200 I/O modules), ensuring reliable data exchange in industrial environments. With support for open architectures (e.g., IEC 61850 for power applications), the module offers flexibility for digital substation deployments and scalable automation systems. Its compact DIN rail design (4.5 cm × 10.2 cm × 13.4 cm) and hot-swap capability minimize downtime, making it ideal for industries requiring high availability.

3. Advantages and Features
- Open Architecture: Supports Profibus-DP and IEC 61850 for interoperability with third-party devices.
- Modular Flexibility: Hot-swap functionality and plug-and-play connectivity reduce maintenance downtime.
- Reliable Performance: Galvanic isolation (2.5kV) protects against voltage spikes; MTBF ≥ 100,000 hours (IEC 61709).
- Space Efficiency: Compact design saves 30% rack space compared to legacy modules.
- Cost Optimization: Pre-configured kits (e.g., CI858K01 + TP851 baseplate) lower installation costs.
4. Application Areas and Use Cases
Industries: Power generation (digital substations), manufacturing (assembly lines), oil & gas (process control), and utilities (water treatment).
Applications: Distributed I/O communication, remote device monitoring, and industrial Ethernet/Profibus-DP network integration.
Applications: Distributed I/O communication, remote device monitoring, and industrial Ethernet/Profibus-DP network integration.
Case Study: A 500kV digital substation in Europe adopted CI858K01 modules to connect 200+ intelligent electronic devices (IEDs) via Profibus-DP. The module’s IEC 61850 compliance and real-time data processing reduced communication latency by 20%, improving grid stability and fault detection accuracy.
5. Competitor Comparison
Compared to similar Profibus-DP modules, the CI858K01 offers:
- Wider Voltage Range: 5–40V DC (vs. 24V DC typical), suitable for diverse field environments.
- Modular Kits: Pre-integrated baseplates (e.g., TP851) enable 15% faster installation than standalone alternatives.
- Legacy Support: Backward compatibility with S200 I/O systems (critical for retrofit projects), unlike newer-generation modules (e.g., CI854AK01).

6. Selection Recommendations
- Compatibility: Ensure alignment with ABB’s AC800M platform or S200 I/O systems.
- Network Requirements: Choose Profibus-DP (CI858K01) for legacy networks; upgrade to Ethernet/IP (CI854AK01) for modern systems.
- Environment: Verify temperature/humidity ranges (e.g., -20°C to +60°C for indoor use).
- Budget: Opt for pre-configured kits (CI858K01 + TP851) for cost savings in retrofits; balance with newer modules for greenfield projects.
7. Precautions
-
Installation: Use ESD-safe tools; follow ABB’s wiring guidelines for Profibus-DP termination.
-
Compliance: For new installations post-2017, replace with RoHS-compliant alternatives (CI854AK01/CI854BK01).
-
Maintenance: Regularly update firmware via ABB’s Control Builder M; inspect terminal connections for corrosion.
-
Safety: Disconnect power before module replacement; adhere to IEC 61010-1 safety standards.
