Product Overview
The ABB UAD141A02 (3BHE012095R0002) is a basic industrial control module optimized for distributed automation and process control systems. It serves as a field interface and signal processing board, connecting process instruments and controller logic. Its design makes it suitable for both new installations within large automation system control racks or I/O stations, as well as for maintenance and replacement.
Core Capabilities
Process signal interface: Converts and modulates field signals (analog or digital) for use by upper-level control logic.
Distributed I/O compatibility: Works with remote I/O base stations and controller processors, supporting system expansion.
Modular replacement parts: 1:1 replacement available in ABB control environments for easy and rapid maintenance.
Rack-mount design: Form factor suitable for installation in automation cabinets or backplane slots.
