        Features:

        • Enables connection of S800 I/O and Select I/O systems to Ethernet networks for industrial automation and distributed control.
        • Supports fault-tolerant operation with two CI845 modules, two TC810 adapters, and one TU860/TU865 termination unit.
        • When combined with HI880 module, the CI845 can be used in Select I/O High Integrity SIL3 safety applications.
        The CI845 serves as a dedicated Ethernet Fieldbus Communication Interface Module, bridging the gap between field I/O systems and industrial Ethernet networks. It is specifically designed for connection of S800 I/O or Select I/O systems, enabling seamless data exchange between field devices and higher-level control systems such as ABB 800xA. The module acts as a communication gateway, handling protocol conversion and data buffering to ensure deterministic performance.

        For mission-critical applications requiring high availability, the CI845 supports fully redundant configurations. A redundant setup requires two CI845 modules, two TC810 Ethernet Adapters, and one TU860 or TU865 termination unit. The two CI845 modules operate in parallel, continuously monitoring each other's health. If the primary CI845 fails, the secondary module automatically takes over communication duties without interrupting data flow to the S800 or Select I/O systems.

        The CI845 can be extended to support Select I/O High Integrity SIL3 applications, meeting the highest safety integrity level defined by IEC 61508. To achieve SIL3 capability, one HI880 module must be added to the CI845 configuration. The HI880 module provides additional diagnostics, self-checking, and fail-safe features required for safety-related functions such as emergency shutdown (ESD) and fire and gas (F&G) systems. When configured with HI880, the CI845 can safely transmit I/O data from Select I/O modules in safety-critical loops.

        The CI845 ABB Communication Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

        Description
        The CI845 Ethernet FCI module enables seamless communication between S800 I/O or Select I/O systems and Ethernet networks. This fieldbus communication interface is designed for industrial automation environments requiring reliable data exchange.

        For Select I/O High Integrity SIL3 applications, the CI845 requires one HI880 module. The CI845 measures 135mm height, 30mm width, and 76.3mm depth, weighing only 0.245 kg. This compact form factor allows easy integration into control cabinets. 

        The CI845 complies with EU Directive 2011/65/EU (RoHS) and falls under WEEE Category 5 (Small Equipment with no external dimension exceeding 50 cm). 

        Typical applications for CI845 include connecting S800 I/O systems to Ethernet networks in distributed control systems like ABB 800xA. The CI845 can also be used with Select I/O systems where deterministic communication is required.
