Product Overview

The ABB 3AUA489002B4562 is a versatile industrial control PCB card engineered for ABB’s extensive automation ecosystem. This component primarily functions as a 16-channel digital output module with relay-type outputs, providing galvanic isolation between the control logic and field devices . Designed for integration into ABB drive systems, PLC cabinets, and distributed control architectures, the ABB 3AUA489002B4562 translates controller logic signals into physical switching actions that drive solenoid valves, contactor coils, indicator lamps, and other field actuators.

The ABB 3AUA489002B4562 features 16 independent SPST (Single Pole Single Throw) normally-open relay outputs, each rated at 2A for resistive loads with a maximum switching voltage of 250V AC or 30V DC . The channels are arranged in two groups of eight, each with a common terminal and a group current limit of 10A. This configuration makes the ABB 3AUA489002B4562 particularly suitable for applications requiring direct switching of AC-powered devices without intermediate interface relays . Some sources also identify the ABB 3AUA489002B4562 as a drive internal PCB card used for signal conditioning and internal logic communication within ACS series variable frequency drives, highlighting the component’s role across multiple ABB product platforms . The card’s industrial-grade construction, featuring multilayer FR4 PCB material and conformal coating options, ensures reliable operation in demanding control cabinet environments with temperatures ranging from -20°C to +70°C .
