Description

Delivering precise voltage control within the Sysmac automation platform, the Omron NX-DA2603 analog output unit provides reliable high-density analog signal generation in a space-saving 12 mm form factor. Designed for seamless integration with NX-series CPU Units or EtherCAT Coupler Units, this module features a 2-point output capacity operating over a -10 to +10 V range. Utilizing the optimized Free-Run refreshing method, the module ensures steady signal performance across continuous processing demands while maintaining robust galvanic isolation from the system bus to protect sensitive upstream logic controllers.

Key Features

  • Dual-point voltage output (-10 to +10 V) with independent channel configuration.
  • Free-Run refreshing mechanism for stable, continuous signal conversion.
  • Integrated TS status LED diagnostic indicator for immediate field operational checks.
  • High-integrity isolation barrier utilizing power transformers and digital signal isolators.
  • Ultra-slim 12 mm housing profile maximizing din-rail spacing inside compact control enclosures.
  • Toolless push-in Plus terminal block system for rapid, vibration-resistant field wiring.

Applications

  • Proportional control of hydraulic valves and pneumatic pressure regulators.
  • Speed reference commanding for variable frequency drives (VFDs) and servo controllers.
  • Analog input retransmission to external data acquisition and plant monitoring systems.
  • Setpoint distribution to localized temperature control loops.

Installation Guidelines

CRITICAL WARNING: electrical shock hazard

Ensure the main power supplies to both the NX-bus and the field devices are completely de-energized before mounting, removing, or wiring the module. Failure to observe this protocol can cause irreversible damage to the internal logic components or unexpected field device behavior.

1

Align the module side-connecting guides with the adjacent NX unit on the DIN rail track.

2

Slide the NX-DA2603 firmly onto the DIN rail until you hear an audible click, indicating the bus connector is fully locked into position.

3

Wire signal cables using ferrules into the Push-in Plus terminals. Secure signal shielding to a functional ground bar to minimize high-frequency noise interference.

FAQ

What is the output range of the NX-DA2603 unit?

The module operates exclusively with a voltage range of -10 to +10 V across 2 analog output channels.

Does the NX-DA2603 support synchronous refreshing modes?

No, this module utilizes the Free-Run refreshing method, which updates outputs independently of the controller's task execution cycle.

Are the individual output channels isolated from one another?

No. While there is digital and power transformer isolation between the internal NX bus and the analog circuitry, there is no isolation between the individual output channels.

What type of connection interface is used for field wiring?

The unit is equipped with a toolless Push-in Plus terminal block, designed to speed up wiring and resist machine vibrations.
