Product Description

Description

Designed for high-speed and high-precision data acquisition within industrial automation systems, the Omron NX-AD2608 is a high-performance analog input module featuring 2 differential voltage input channels. Operating within the Sysmac platform, this module converts external analog voltage signals ranging from -10 V to +10 V into high-resolution digital values. With a conversion rate of 10 microseconds per point and a high resolution of 1/30000, it is engineered for applications demanding tight process control and rapid response times.

The Omron NX-AD2608 supports switching between synchronous I/O refreshing and Free-Run refreshing, allowing precise synchronization with the controller CPU or communications coupler unit. The module features a compact, space-saving design with a width of just 12 mm, and integrates a screwless clamping terminal block for fast, reliable wiring in high-vibration environments.

Features

  • Two independent differential voltage input channels with a range of -10 to +10 V.
  • Exceptional conversion speed of 10 us per point for high-speed automation loop responsiveness.
  • High measurement resolution of 1/30000 for precise feedback.
  • Flexible I/O refreshing methods: Switching synchronous I/O refreshing and Free-Run refreshing.
  • Integrated screwless clamping terminal block (8 terminals) for simplified wiring and maintenance.
  • Robust isolation via transformer (power) and digital isolator (signal) between inputs and the NX bus.
  • Status indication via a dedicated TS indicator on the front panel.

Applications

  • High-speed motion control and servo system feedback loops.
  • Factory automation and packaging machinery.
  • Precision temperature, pressure, or flow monitoring systems.
  • Data logging and process monitoring in manufacturing lines.

Installation Guidelines

  • Mounting: Mount the unit onto a standard 35 mm DIN rail. Ensure the unit clicks securely into place alongside adjacent NX-series I/O modules.
  • Wiring: Use solid wires or stranded wires with ferrules. Insert the wire directly into the screwless clamping terminal block without the use of tools. To remove, press the release button with a flat-head screwdriver.
  • Noise Mitigation: Utilize shielded twisted-pair cables for analog input lines. Keep signal wiring separated from high-voltage power lines and motor drive cables to prevent electromagnetic interference.
  • Grounding: Ensure the functional ground terminal on the DIN rail is properly grounded according to local industrial electrical codes.
