Omron NX-PA9001 NX-Series Power Supply Unit

Description

Designed for stable system operation within high-performance automation configurations, the Omron NX-PA9001 serves as a robust AC power supply unit for the NX-series controllers. This module converts wide-range utility input power into regulated internal power, ensuring reliable backplane voltage distribution for connected I/O and CPU modules. Operating on a wide-range input voltage, the unit accommodates global industrial power grids while providing structural system stability and integrated RUN output contact relay functionality.

Features

• Wide-range AC input capability supporting nominal voltages from 100 to 240 VAC.
• Integrated RUN output SPST-NO contact for system status signaling and external interlock control.
• Robust electrical isolation between external AC terminals and the ground (GR) terminal.
• High-capacity 90 W power delivery to support multi-module NX-series expansions.

Applications

• Industrial factory automation platforms utilizing Omron NX-series Sysmac controllers.
• Packaging, material handling, and assembly line control panels.
• Water treatment facilities, municipal infrastructure, and general machine control networks.

Installation Guidelines

• Mounting: Mount securely onto a 35 mm DIN rail inside a dust-free, enclosed industrial control cabinet.
• Grounding: Connect the GR (Ground) terminal directly to a dedicated functional ground point with a grounding resistance of 100 Ohms or less to mitigate electromagnetic noise.
• Wiring: Use appropriate wire gauges matching the rated current and voltage demands of the AC input line. Ensure crimp terminals are fully secured on the terminal block.
• Cooling and Ventilation: Maintain specified clearance gaps above and below the NX-PA9001 module to ensure sufficient natural convection cooling during operation.
