ABB CI868K01-eA 3BSE048845R2 Communication Interface Kit

‑ Power Supply：Power supplied from CEX bus；typical power consumption 5.5W

‑ Mechanical Structure：standard S500 rack single‑slot plug‑in kit, matched with TP868 baseplate；overall weight approx 0.70 kg

‑ On‑board Resources：IEC61850 protocol processing unit, dual‑channel ethernet driving circuit, GOOSE message processing unit, data buffer memory, CEX back‑plane bus controller, module self‑diagnosis circuit

‑ Communication Interface：internal CEX bus for data interaction with AC800M‑eA controller；two independent galvanic‑isolated RJ45 ethernet interfaces, 10/100Mbit/s auto‑adaptive

‑ Galvanic Isolation：galvanic isolation between ethernet side and controller internal logic side, isolation rating 2500 VAC

‑ Core Function：IEC61850 MMS client communication, GOOSE message publish‑subscribe, power‑station device data mapping interaction, bus fault diagnosis, hot‑swap support

‑ Protection：ethernet‑port surge‑suppression and ESD protection

‑ Status LED Indicators：Power indicator, Module Fault indicator, dual‑channel communication status LED, GOOSE status indicator

‑ Weight：approx 0.70 kg

‑ Installed in S500 standard rack via TP868 baseplate, communicates with AC800M‑eA series controller through internal CEX bus. Single CEX bus supports up to 12 CI868K01‑eA modules, subject to actual bus load.

‑ Dedicated for IEC61850 substation communication, supports MMS client mode to read measurement value, device parameter, alarm‑event information of bay‑level IED equipment; supports GOOSE message receiving and publishing, completes fast inter‑locking signal transmission between DCS and substation protection devices. Two ethernet ports work independently, can connect to different substation network segments, module itself does not support network line redundancy. Realizes bidirectional mapping between IEC61850 object data and Control Builder‑M control variables, implements periodic measurement data collection and non‑periodic remote control, parameter adjustment. Only fits for AC800M‑eA series controller, cannot be used on ordinary AC800M hardware platform.

‑ Built‑in high‑speed data buffer guarantees real‑time performance of GOOSE fast message. Supports hot‑swap, module can be replaced without rack power‑off during maintenance, brief communication interruption will occur in swapping process.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware integrity; detects hardware fault and IEC61850 ethernet communication abnormality, reports fault word and alarm information to AC800M‑eA controller.

‑ Cannot run independently; must cooperate with S500 rack, TP868 baseplate and AC800M‑eA controller. CI868K01‑eA 3BSE048845R2 is complete kit version for eA‑generation controller, cannot work without TP868 baseplate, cannot substitute ordinary CI868K01 for standard AC800M.

‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED and report fault alarm word to AC800M‑eA controller.

‑ No local historical‑data storage; module status and fault codes need to be read through Control Builder‑M configuration‑monitoring tool.

‑ Module hardware failure will cause IEC61850 network communication breakdown; controller internal logic keeps normal operation, but data interaction with all connected substation IED intelligent devices fails.

‑ Back‑plane connector: inserts into S500 rack slot via TP868 baseplate, connects to CEX internal bus of AC800M‑eA controller.

‑ External dual RJ45 female connectors: connect industrial shielded ethernet cables to IEC61850 substation communication network and field IED devices.

‑ Mounting：insert into S500 standard rack single slot with TP868 baseplate

‑ Operating Temperature：‑20 ℃ ~ +55 ℃

‑ Storage Temperature：‑40 ℃ ~ +85 ℃

‑ Relative Humidity：5‑95 %RH, non‑condensing

‑ Pollution degree：Degree 2

‑ Protection Class：IP20, cabinet‑internal installation.

‑ Cut off control cabinet auxiliary power before inserting or replacing this module, although module supports hot‑swap, power‑off operation is recommended for spare‑part replacement. Configure IEC61850 communication parameters, IED device list, data object mapping and GOOSE control‑block parameters according to power‑station project requirements, adopt industrial shielded ethernet cable for field wiring. This hardware is exclusive for AC800M‑eA platform, incompatible with traditional AC800M CPU. Two ethernet ports are independent, does not support network line‑redundancy function. It is recommended to replace module together with TP868 baseplate for spare‑part maintenance.

‑ For spare‑part replacement: verify full model CI868K01‑eA and part‑number 3BSE048845R2; after installation check back‑plane power‑supply, verify bidirectional data interaction between controller and substation IED equipment. Hardware‑version mismatch will bring risk of bus communication parsing abnormality and platform incompatibility.

‑ Module fault will result in communication failure of all IEC61850 IED devices under corresponding network channel.
