Description

Engineered for high-speed, precise voltage data acquisition within the Sysmac automation platform, the Omron NX-AD2604 provides two differential analog input channels. This NX Series Analog Input Unit features a bipolar voltage range of -10 to +10 VDC, making it ideal for interfacing with standard industrial sensors, transmitters, and transducers. Utilizing a screwless clamping terminal block, this module simplifies electrical panel installation while maintaining secure, vibration-resistant connections. Dynamic data updating is achieved via the Free-Run refreshing method, ensuring reliable, real-time performance in demanding B2B control environments.

Features

  • Two high-resolution differential analog inputs with 1/8000 conversion resolution
  • Bipolar input voltage range of -10 to +10 VDC
  • Rapid conversion time of 250 microseconds per point
  • Free-Run refreshing operation for real-time monitoring and processing
  • Screwless clamping push-in terminal block (8 terminals) for fast, secure wiring
  • Integrated front-facing TS status indicator for immediate diagnostics
  • Power transformer and digital isolator protection between inputs and the internal NX bus

Applications

  • Process loop monitoring in water treatment and chemical processing plants
  • Sensor integration for precise pressure, flow, and temperature transmitters
  • Factory automation systems requiring high-speed differential voltage logging
  • Turbine, motor, and heavy machinery control system monitoring

FAQ

What is the voltage range and resolution of the Omron NX-AD2604?

The Omron NX-AD2604 supports an analog voltage input range of -10 to +10 VDC with a resolution of 1/8000.

Does the NX-AD2604 offer channel-to-channel isolation?

No. While there is isolation between the input channels and the internal NX bus (via transformers and digital isolators), there is no physical electrical isolation between the individual input channels.

What terminal block type is used on this analog input unit?

The module utilizes an integrated 8-terminal screwless clamping push-in terminal block, which eliminates the need for screws and speeds up installation.

What is the conversion speed of the NX-AD2604?

This module has a conversion time of 250 microseconds per point.
