ABB TP854 Overview
The ABB TP854 is a communication interface base (backplane) developed by ABB for its industrial automation systems, particularly the AC 800M / S800 series. It is primarily used for mounting and supporting the CI854 series fieldbus communication modules (such as CI854, CI854A, and CI854B), enabling reliable PROFIBUS DP (or DP-V1) fieldbus connectivity.
Key Functions
-
Provides mechanical support and electrical connection interface for CI854 communication modules.
-
Supports various fieldbus protocols such as PROFIBUS DP/DP-V1 and FOUNDATION Fieldbus, enabling high-speed data exchange between controllers, field I/O, and remote I/O systems.
-
Includes termination units and terminal resistors to ensure signal integrity and noise immunity across the bus network.
