Product Introduction
Communication modules in a DCS system are useless if they don’t have a reliable physical and electrical foundation. The ABB 3BSE018126R1 TP853 is a dedicated baseplate designed specifically to support and connect CI853, CI855, CI857, and CI861 communication modules. It acts as the critical intermediary between the module and the control cabinet’s DIN rail, ensuring proper alignment and secure backplane connectivity.
Engineers rely on the ABB 3BSE018126R1 TP853 because it provides the high-reliability mechanical and electrical interface required for continuous industrial operation. With precise dimensions of 45mm x 63mm x 162mm and a robust 0.5 kg construction, the 3BSE018126R1 TP853 guarantees that your communication modules remain securely seated even in high-vibration environments. Bottom line — it’s a simple, passive component, but if it fails or is missing, your entire communication node goes down.
QA/QC Transparency SOP
- Intake & Origin Verification: We verify the 3BSE018126R1 TP853 part number and inspect the DIN rail clip and module mounting points for physical damage or stress fractures.
- Live Functional Testing: The baseplate is mounted on a test rack with a compatible CI853 module to verify mechanical seating and backplane pin alignment.
- Electrical Parameter Tests: We use a multimeter to check continuity across all backplane connection points to ensure there are no internal trace breaks.
- Firmware/Config Verification: N/A (Passive hardware component).
- Final QC & Anti-Static Packaging: The 3BSE018126R1 TP853 is sealed in an ESD-safe bag to prevent corrosion on the backplane contacts during storage.
Field Engineer Gotchas
- Module Compatibility Confusion:
Risk: The is specifically designed for CI853, CI855, CI857, and CI861 modules. Attempting to mount a different CI-series module will result in misalignment and potential damage.
Solution: Cross-reference the module part number with the baseplate compatibility list.
Warning: I’ve seen techs try to force a CI851 onto this baseplate. It doesn’t fit, and bending the pins will ruin both the module and the base. - DIN Rail Clip Failure:
Risk: The plastic DIN rail clip on the can become brittle over time, especially in high-temperature cabinets.
Solution: Inspect the clip before installation. If it looks cracked or feels loose, replace the baseplate.
Warning: A loose baseplate can cause intermittent communication faults that are a nightmare to troubleshoot. - Backplane Pin Damage:
Risk: When mounting the communication module, if the is not perfectly aligned, the backplane pins can bend.
Solution: Ensure the module is flush against the baseplate before tightening any mounting screws.
Warning: Never force the module down. If it requires excessive pressure, pull it back and check for obstructions.

Application Scenarios
- AC800M Controller Networks: The ABB is used in control cabinets to mount Profibus or Ethernet communication modules, providing the physical link between the AC800M CPU and the fieldbus network.
- Distributed I/O Stations: In remote I/O racks, the supports the communication interface module that connects the distributed I/O back to the central controller.
- Legacy System Retrofits: Plants upgrading from Advant OCS to AC800M use the to ensure their existing communication modules have a proper mounting platform in the new control architecture.
FAQ
No. The is specifically designed for CI853, CI855, CI857, and CI861 modules. The CI830 uses a different baseplate.
Is this baseplate hot-swappable?
The baseplate itself is passive, but you should never attempt to remove or install it while the backplane is powered. Always power down the rack first.
No. The is a purely mechanical and electrical passive component. It contains no active electronics or firmware.
The 3BSE018126R1 is the specific ABB order number. Always use the full part number to ensure you receive the exact hardware revision compatible with your system.
Can I mount this baseplate on a standard 35mm DIN rail?
Yes. The is designed for standard 35mm DIN rail mounting, which is the industry standard for industrial control cabinets.
How do I know if my baseplate is failing?
Baseplates rarely fail electronically, but mechanical issues like broken DIN clips, stripped mounting threads, or corroded backplane contacts can cause problems. Inspect the visually during maintenance.
Is this the same as a terminal baseplate?
No. The is a communication module baseplate. Terminal baseplates (like TB8xx series) are used for I/O modules and have different wiring and pin configurations.
