Features:
- Four optical DDCS communication channels
- 5 Mbit/s channel 0 for N-type fieldbus adapters
- Revision-dependent channel 1 communication rate
ABB designed SDCS-COM-82 as the optical DDCS communication interface used inside documented DCS800 control arrangements.
Channel 0 serves N-type fieldbus adapters at 5 Mbit/s, channels 2 and 3 operate at 10 Mbit/s, and channel 1 behavior depends on board revision.
A replacement review should identify the installed revision, occupied optical channels, converter arrangement, connector condition, and fiber routing.
Apter Power can quote the ABB SDCS-COM-82 DDCS Communication Interface Board and help match its optical-channel arrangement.

ABB SDCS-COM-82 DDCS Communication Interface Board Specs
General
- Manufacturer ABB
- Model SDCS-COM-82
- Condition New and Original
- Product Family DCS800
- Channel 0: This 5 Mbit/s channel supports N-type fieldbus adapters.
- Channel 1: The rate is 5 Mbit/s on revisions G-I and 10 Mbit/s on revision K or higher.
- Channel 2: The official hardware manual specifies 10 Mbit/s operation.
- Channel 3: The official hardware manual specifies 10 Mbit/s operation.
- Earlier group: ABB groups board revisions G through I for the documented channel behavior.
- Later group: Revision K and higher uses the later documented channel 1 rate.
- Identification: Read the physical board revision before applying communication settings.
- Ordering: Do not treat another SDCS communication board as the same configuration.
- Power: Remove converter power before handling the interface board.
- ESD: Follow ABB electrostatic-discharge precautions during service.
- Fibers: Match every optical fiber to its documented channel and connector.
- Configuration: Check DCS800 DDCS settings after the hardware is installed.
