ABB CI810B 3BSE020520R1 Fieldbus Communication Interface Module

‑ Power Supply：Supplied by S500 rack back‑plane 24 VDC；typical power consumption 6.8 W

‑ Mechanical Structure：standard S500 rack plug‑in module；weight approx 0.68 kg

‑ On‑board Resources：AF100 bus protocol processing unit, bus driving circuit, data buffer memory, back‑plane bus controller, module self‑diagnosis circuit

‑ Communication Interface：internal back‑plane bus for data interaction with AC800M controller; terminal‑block type AF100 fieldbus external interface

‑ Galvanic Isolation：galvanic isolation between external AF100 bus side and controller internal logic side, isolation rating 2500 VAC

‑ Core Function：AF100 field‑bus protocol processing, cyclic data interaction between controller and remote S800 I/O stations, bus fault diagnosis

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

‑ Status LED Indicators：Power indicator, Module Fault indicator, bus communication sending‑receiving status LED

‑ Weight：approx 0.68 kg

‑ Installed in S500 standard rack, communicates with AC800M series controller via rack back‑plane bus. Realizes AF100 bus master‑station function, connects multiple remote S800 I/O cabinets through AF100 dedicated shielded cable.

‑ Cyclically reads analog and binary input signals from field S800 I/O modules, transmits process data to AC800M controller; receives control output commands from controller and distributes to corresponding remote S800 output modules, realizes distributed I/O expansion for 800xA system.

‑ Built‑in data buffer improves communication stability under multi‑node bus networking, reduces data loss risk caused by bus fluctuation.

‑ Module self‑diagnosis monitors back‑plane power‑supply and on‑board hardware integrity; detects hardware fault, bus short‑circuit and bus‑off fault, reports fault word to AC800M controller.

‑ Cannot run independently; must cooperate with S500 rack and AC800M series controller. CI810B 3BSE020520R1 is dedicated AF100 bus communication board, cannot be substituted by general‑purpose communication 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 AF100 bus communication breakdown; controller local logic keeps normal operation, but all remote S800 I/O stations on this AF100 bus lose communication, field data acquisition and control output fail.

‑ Back‑plane connector: inserts into S500 rack slot, connects to internal bus of AC800M controller.

‑ External AF100 terminal block: connect dedicated AF100 shielded bus cables to remote S800 I/O cabinets.

‑ Mounting：insert into S500 standard rack slot

‑ Operating Temperature：‑20 ℃ ~ +60 ℃

‑ Storage Temperature：‑40 ℃ ~ +85 ℃

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

‑ Protection Class：IP20, cabinet‑internal installation.

‑ Cut off control cabinet auxiliary power before inserting or replacing this module. Use dedicated AF100 shielded cables, install terminal terminator at both ends of AF100 bus trunk.

‑ For spare‑part replacement: verify full model CI810B and part‑number 3BSE020520R1; after installation check back‑plane power‑supply, verify cyclic data interaction between controller and each remote S800 I/O station. Hardware‑version mismatch will bring risk of bus communication parsing abnormality.

‑ Module fault will result in total communication failure of DCS system remote AF100 S800 I/O stations.
