ABB 3BDH000022R1 CI801 Redundant Profibus-DP Communication Interface Module (Freelance 800F DCS Series) Core Function: This is the factory redundant paired variant of the standard CI801 (3BDH000021R1) Profibus-DP communication module for ABB Freelance 800F distributed control systems. It establishes dual redundant Profibus-DP bus links between AC 800F controllers and field Profibus slaves (S800 I/O, drives, transmitters, valve positioners). It supports automatic hot standby switchover without process interruption, delivers cyclic real-time process data exchange, continuous bus diagnostic monitoring, and galvanic isolation to eliminate ground loop interference. Designed for high-reliability critical industries where single-bus failure risks unplanned downtime. 2) 3B

| ABB Freelance 800F series | AC 800F, PM 802F, PM 803F, PM 804F controllers |
| Root Cause | Cabinet poor airflow, dust accumulation on PCB components, high continuous ambient temperature. Symptom: Module auto-disconnects both bus channels once temperature exceeds 60°C. |
| Note | Cost-effective substitute for low-slave-count networks; limited to maximum 64 Profibus DP slaves, no native hot standby redundancy. |
| Power | 4.5 W Mounting |
| Connector | 9-pin D |
| Mounting | DIN rail |
| Speed | 9.6 kbps |
| Speed 2 | 12 Mbps |
| Redundancy | CI801 Redundant |
