Description

Precision data acquisition in modern machine control requires reliable, high-speed interfaces like the Omron NX-AD2208. This high-performance analog input unit is designed for the Omron NX Series platform, offering two differential channels dedicated to standard 4 to 20 mA analog current loops. Utilizing a high-resolution conversion of 1/30,000 and an ultra-fast conversion time of 10 us per point, it ensures rapid signal processing for demanding real-time industrial applications. The unit features flexible timing with support for both synchronous I/O refreshing and Free-Run refreshing, adapting perfectly to different system architectures via EtherCAT couplers or direct CPU connection.

Features

Two differential analog input channels dedicated to 4 to 20 mA signals.
Ultra-fast signal processing with a conversion time of 10 us per point.
High-resolution performance at 1/30,000 for precise process measurements.
Supports switching between synchronous I/O refreshing and Free-Run refreshing.
Screwless clamping terminal block with 8 terminals simplifies field wiring and resists vibration.
Integrated TS status indicator for immediate diagnostics.
Galvanic isolation between the input channels and the NX bus using a power transformer and digital isolator.

Applications

Continuous process monitoring (flow, pressure, and level transmitters).
High-speed industrial closed-loop feedback systems.
Water treatment facilities and chemical dosage monitoring.
OEM machinery integration with Sysmac NJ/NX controller networks.

Installation Guidelines

Mounting: Mount the unit directly onto a standard 35 mm DIN rail. Ensure the interlocking side-connector blocks securely lock into adjacent NX modules.
Wiring: Use solid wires or stranded wires with ferrules. Push directly into the screwless clamping terminal block without using tools. To release, use a small flat-blade screwdriver on the release button.
Shielding: Connect the shielded outer conductor of the analog input cables to a functional ground bar to reduce electro-magnetic noise.
Environmental Maintenance: Maintain proper panel ventilation to ensure the operating environment remains within 0 to 55 degC.
