ABB CI856K01 3BSE026055R1 Kit

CI856K01 is an S100 I/O communication interface kit for the ABB Ability™ System 800xA® series, designed for use with AC 800M control systems. It consists of the CI856 Communication Interface Module and the TP856 Baseplate. The product is specifically engineered for industrial automation environments requiring high reliability and real-time I/O communication, suitable for process control and monitoring systems.

CI856K01 enables efficient data exchange between AC 800M controllers and the S100 I/O system, supporting connection of up to five S100 I/O racks, with each rack capable of accommodating up to 20 I/O modules. Its design balances ease of installation, system compatibility, and maintenance convenience, making it suitable for automation control applications in industries such as chemicals, power, oil and gas, and pharmaceuticals.

2. Product Composition and Structure

2.1 CI856 Communication Interface Module

The CI856 is the core communication processing unit, integrating the following functional modules:

• CEX-Bus interface logic for communication with the AC 800M processor unit;

• S100 I/O bus logic responsible for scanning and updating connected S100 I/O modules;

• Built-in CPU for handling communication protocols and data exchange;

• DC/DC converter that converts the +24V power supply from the CEX-Bus to the voltages required by the module.

2.2 TP856 Baseplate

The TP856 provides mechanical mounting and electrical connection support for the CI856, featuring:

• 36-pin centerline miniature ribbon connector (female) for connecting S100 I/O rack cables (models TK575/TK580);

• Code lock mechanism using a preset two-letter alpha code locking device to prevent installation of incompatible modules;

• DIN-rail mounting design compliant with industrial standards for easy integration into control cabinets.

3. Key Features and Benefits

3.1 High-Performance Communication Capability

• Supports up to 5 S100 I/O racks, each with up to 20 I/O modules;

• Minimum cyclic scan/update interval of 0.2 ms (actual performance depends on I/O type and quantity);

• Enables real-time data acquisition and control output, suitable for high-speed process control.

3.2 System Compatibility and Extensibility

• Reuses existing I/O installations, terminal blocks, and field wiring from legacy ABB Master and Advant OCS systems, protecting customer investment;

• Seamlessly integrates with AC 800M controllers via the CEX-Bus;

• Supports hot swap functionality, allowing module replacement during system operation to enhance availability.

3.3 Ease of Installation and Maintenance

• DIN-rail mounting for compact and simple installation;

• Modular design supports quick replacement;

• Clear LED status indicators facilitate fault diagnosis.

3.4 Safety and Reliability

• Code lock design prevents installation of incompatible modules;

• Features galvanic isolation protection;

• Complies with industrial environmental protection rating IP20 (EN60529/IEC 529).

4. Installation and Connection Guidelines

4.1 Installation Steps

1. Mount the TP856 baseplate onto a standard DIN rail;

2. Insert the CI856 module into the TP856 baseplate, ensuring the code lock matches;

3. Connect the S100 I/O rack to the 36-pin connector on TP856 using TK575/TK580 cable;

4. Power on the system and check the module LED status.

4.2 Electrical Connection Notes

• Ensure the +24V power supply meets requirements;

• Avoid routing connection cables parallel to high-interference sources;

• Grounding should comply with industrial automation system standards.

5. LED Indicator Description

The CI856 module features three LED indicators on the front panel, with the following meanings:

6. Application Scenarios

CI856K01 is suitable for the following industrial automation scenarios:
