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.
