Overview
The ABB TP853 is a passive baseplate/termination unit (TU) for the S800 I/O modules within the System 800xA and AC 800M platforms. It is not an active electronic module, but it provides the physical mounting, field wiring interface, and electrical connections for DI, DO, AI, and AO modules. Its design ensures reliable signal routing, mechanical stability, and supports hot-swappable I/O modules, enabling maintenance or replacement without process interruptions. Therefore, the TP853 is a critical enabler for the physical and electrical integrity of the S800 I/O subsystem.

FAQ: ABB TP853 Baseplate Module Termination
Q1: Why is the TP853 called a "Termination Unit" or "Baseplate"?
A1: It is the termination point for field wiring and provides the physical base for mounting S800 I/O modules.
Q2: Does the TP853 contain any active electronics or intelligence?
A2: No, it is purely passive with only connectors, terminals, and the Unit Identification Plug (UIP). Active signal processing resides in the pluggable I/O module.
Q3: What is the purpose of the Unit Identification Plug (UIP)?
A3: The UIP tells the AC 800M controller which I/O module type is installed, preventing incorrect module insertion and ensuring system integrity.
