Description
I. ABB NBRA-663 — Inverter Output Module
1. Product Overview
The NBRA-663 is a dedicated digital output module for ABB’s ACS800 series frequency converters , belonging to the ABB drive I/O expansion module family (NBRA-6xx series). Installed in the internal expansion slot of the ACS800 frequency converter, it provides the drive with additional digital output channels for controlling external devices such as relays, contactors, indicator lights, and solenoid valves.
This module is an original ABB industrial control spare part, widely used in variable frequency speed control systems that require multi-channel digital output control.
