ABB TP853 | 3BSE018126R1 | Module Termination Unit Baseplate
Product Overview
The TP853 (3BSE018126R1) is a specialized Module Termination Unit (MTU) baseplate designed for ABB’s System 800xA and Advant Controller environments. It serves as the essential mechanical and electrical interface for a specific range of communication modules, including the CI853, CI855, CI857, and CI861. By providing a fixed platform for field wiring and bus connections, the TP853 allows communication modules to be plugged in or replaced without disturbing the permanent wiring, significantly reducing downtime during maintenance or system expansion.
Technical Specifications
The TP853 (3BSE018126R1) is built to exacting industrial standards to ensure high-speed signal integrity across the DCS backplane.

Core Performance Features
-
Hot-Swap Capability: The TP853 (3BSE018126R1) supports the "hot-swap" feature of CI-series modules, allowing for hardware replacement while the rest of the controller subrack remains powered and operational.
-
Passive Baseplate Design: As a passive component, the TP853 contains no active electronics that can fail, ensuring that the critical wiring path remains intact for the lifetime of the control system.
-
Streamlined Maintenance: The vertical orientation and compact 45mm width allow for high-density installation in standard industrial cabinets, maximizing rail space.
-
Secure Signal Grounding: Features dedicated grounding points to protect sensitive RS-232 or MasterBus signals from electromagnetic interference (EMI).
