Omron NX-AD3204 NX-Series Analog Input Unit

Description

High-performance analog signal acquisition is achieved via the Omron NX-AD3204 analog input module, designed for integration within the Sysmac automation platform. This high-density NX-Series Analog Input Unit provides 4 channels of differential current inputs optimized for 4 to 20 mA signals, delivering the reliability and precision required for demanding process control environments.

Operating with a conversion speed of 250 us per point and a high-resolution performance of 1/8000, this unit ensures synchronous high-speed data acquisition when paired with EtherCAT bus couplers. The differential input design provides superior common-mode noise rejection, protecting signal integrity from electromagnetic interference on the factory floor.

Features

• Provides 4 differential analog input channels dedicated to current signals.
• Standard 4 to 20 mA input range compatible with most industrial transmitters and sensors.
• Fast conversion times of up to 250 us per point for high-speed application loops.
• High resolution of 1/8000 for precise variable tracking and control.
• Differential input method minimizes electrical noise interference in harsh operating environments.
• Ultra-compact form factor designed for space-saving DIN rail layouts.

Applications

• Process monitoring (flow meters, pressure sensors, and level transmitters).
• Water and wastewater treatment facility control loops.
• Chemical processing and raw material monitoring.
• Factory automation systems integrated via EtherCAT or EtherNet/IP networks.

Installation Guidelines

• Mounting: Mount securely onto a 35 mm DIN rail within a dust-free, dry industrial enclosure.
• Wiring: Use shielded twisted-pair cables for analog signal lines and ensure the shield is properly grounded at the functional ground terminal to prevent signal degradation.
• Terminal Block: Utilize the integrated push-in Plus terminal block for solderless connection of solid or ferruled wires.
• Environment: Ensure ambient operating temperatures remain within official catalog limits, providing adequate ventilation space around the module rack.
