Omron NX-AD3604 NX Series Analog Input Unit

Description

Designed for high-speed, high-precision data acquisition, the Omron NX-AD3604 functions as a high-density analog input module within the Sysmac NX platform framework. This unit provides 4 differential analog input channels configured specifically for voltage signal measurement, offering highly reliable signal processing in electrically noisy industrial environments.

Operating with a fast conversion rate of 250 us per point, the module ensures rapid updates to the controller backplane. With a resolution of 1/8000, it captures precise signal fluctuations from transmitters, sensors, and other field devices. The compact 12 mm housing profile optimizes cabinet space, mounting directly onto standard DIN rails alongside NX-series bus couplers or EtherCAT coupler units.

Features

• 4 differential input channels for stable voltage monitoring.
• Voltage input range of -10 to +10 VDC.
• Fast 250 us conversion time per channel.
• High resolution of 1/8000 for precise control applications.
• Differential input configuration to minimize electromagnetic interference.
• Supports Free-Run refreshing mode for synchronous operations.
• Ultra-slim 12 mm width to conserve control panel space.

Applications

• Continuous monitoring of voltage-generating sensors and transducers.
• Data acquisition in industrial factory automation systems.
• Testing and validation equipment requiring multi-channel voltage sampling.
• HVAC and environmental control systems monitoring transmitter outputs.

Installation Guidelines

• Mounting: Mount horizontally on standard 35 mm DIN rail. Secure with end plates on both sides of the NX assembly to prevent lateral movement.
• Wiring: Use shielded twisted-pair cables for analog signals. Ground the shield at the terminal block or panel grounding bar to prevent signal degradation.
• Power Supply: Ensure the power supply line to the NX bus coupler is isolated and within the specified DC voltage tolerances before powering the unit.
• Ventilation: Maintain standard clearance above and below the module assembly to allow natural convection cooling.
