Description
‑ Power Supply：Supplied by S500 rack back‑plane 24 VDC；typical current consumption 100 mA, typical power consumption 2.4 WABB
‑ Mechanical Structure：standard S500 rack plug‑in module；weight approx 0.30 kg
‑ On‑board Resources：serial protocol processing unit, dual‑channel RS232‑C driving circuit, data buffer memory, CEX back‑plane bus controller, module self‑diagnosis circuit
‑ Communication Interface：internal CEX bus for data interaction with AC800M controller；two 8‑pin RJ45 RS232‑C external serial interfaces
‑ Galvanic Isolation：500V AC isolation between serial port side and controller internal logic side
‑ Core Function：Multi‑protocol serial processing, Modbus RTU / COMLI / 3964R communication, point‑to‑point data transmission, module self‑diagnosis, hot‑swap supportABB
‑ Protection：serial‑port surge‑suppression and ESD protection
‑ Status LED Indicators：Power indicator, Module Fault indicator, channel sending‑receiving status LED
‑ Weight：approx 0.30 kg
‑ Installed in S500 standard rack, communicates with AC800M series controller via rack internal CEX bus, maximum 12 CI853K01 modules can be arranged on one CEX busABB.
‑ Equipped with two independent RS232‑C channels, baud rate selectable from 75bps up to 19200bps. Supports Modbus RTU master/slave, ABB COMLI proprietary protocol, Siemens 3964R protocol, also supports user‑defined serial transparent transmission. Realizes data exchange between controller and field serial instruments, energy‑meters, frequency converters and legacy serial systems.
‑ Each channel works independently, does not interfere with each other. Built‑in data buffer improves serial communication stability and reduces data loss risk. Supports hot‑swap, module can be replaced without power‑off of whole rack.
‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware status; detects hardware fault and serial channel abnormality, reports fault word to AC800M controller.
‑ Cannot run independently; must cooperate with S500 rack and AC800M series controller. CI853K01 3BSE018103R1 is dedicated serial communication board, cannot be substituted by general‑purpose serial modules.
‑ Continuously monitors rack power‑supply and module hardware running state. Fault will activate panel fault LED and report fault alarm word to AC800M controller.
‑ No local historical‑data storage; module status and fault codes need to be read through Control Builder configuration‑monitoring tool.
‑ Module hardware failure will cause corresponding RS232‑C serial channel communication breakdown; controller internal logic keeps normal operation, but data interaction with connected serial devices fails.
‑ Back‑plane connector: inserts into S500 rack slot, connects to CEX internal bus of AC800M controller.
‑ External RJ45 interfaces: two 8‑pin RJ45 ports for RS232‑C serial wiring, needs dedicated conversion cable to connect to field serial devices.
‑ Mounting：insert into S500 standard rack slot
‑ Operating Temperature：0 ℃ ~ +55 ℃ABB
‑ Storage Temperature：‑40 ℃ ~ +70 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Protection Class：IP20, cabinet‑internal installation.
- CI853K01 Dual‑Channel RS232‑C serial communication interface module（3BSE018103R1）
Complementary parts: S500 rack, AC800M series controller, RS232‑C dedicated conversion cables, Control Builder configuration monitoring tool.
‑ 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 baud rate, protocol type, station address according to site serial device requirements. Use matched RJ45‑to‑DB9 conversion cables.
‑ For spare‑part replacement: verify full model CI853K01 and part‑number 3BSE018103R1; after installation check back‑plane power‑supply, verify bidirectional serial data interaction between controller and field serial equipment. Hardware‑version mismatch will bring risk of communication parsing abnormality.
‑ Module fault will result in communication failure of connected RS232‑C serial devices.
Power, petrochemical, metallurgy old‑set AC800M /800xA DCS control cabinets; ABB 800xA system maintenance and spare‑part replacement; industrial spare‑part for serial‑device access gateway unit.
