The Omron NX-DA3605, also cataloged as the NX-DA3605 Analog Output Module, operates as a dedicated hardware component for high-speed linear voltage output generation within Sysmac NX Series automation platforms. Configured with 4 analog output channels, it converts digital controller values into -10 to +10 V analog signals at a 15-bit resolution. The module executes synchronous signal processing with a conversion time of 0.04 ms per unit across the NX I/O bus, facilitating precise closed-loop motion and actuator control.

Technical Specifications Matrix

Deterministic Network Bus & Hardware Integration

Integrated into Sysmac NX backplane structures, the unit processes digital command structures across Profinet / EtherNet/IP deterministic networks with microsecond-level synchronization. High backplane bus communication velocity allows all 4 output channels to update simultaneously without network jitter. The module maintains full firmware flash compatibility across NX series coupler units, enabling seamless dynamic I/O density scaling within compact industrial enclosures.

Cabinet Installation & Field Cabling Directives

• DIN Rail Engagement: Hook the top slot onto a standard 35 mm DIN rail and press the module backward until the lower locking tab latches securely.
• Push-in Wire Termination: Strip solid conductors or insulated ferrules to the specified length and push directly into terminal slots without tools.
• Backplane Bus Insertion: Align side guide connectors with the preceding NX module and slide laterally until the backplane contacts click together.
• Analog Signal Shielding: Use shielded twisted-pair cables for -10 to +10 V voltage loops and terminate shields to the functional ground rail.
• Power Separation: Route analog signal lines in isolated wire ducts separated from high-voltage AC mains and drive output cables.

Frequently Asked Questions

• Is hot-swapping permitted for the NX-DA3605 during active CPU operation?

  No. Backplane power and external supply power must be completely isolated before inserting or removing the slice module from the rack.

• How does synchronous signal processing execute output updates?

  Synchronous processing updates all 4 voltage outputs concurrently in strict synchronization with the CPU primary execution cycle.

• What wire gauge range is compatible with the push-in terminal connectors?

  The push-in terminal block accepts solid or stranded wire with ferrules ranging from AWG 24 to AWG 16 (0.25 to 1.5 mm2).

• What is the conversion speed of the internal DAC circuitry?

  The internal digital-to-analog converter operates at a high conversion rate of 0.04 ms per unit across all active output channels.

• How is analog signal integrity maintained against industrial EMI?

  Differential circuit topology paired with shielded twisted-pair cabling prevents external electromagnetic interference on voltage loops.

• Does the NX-DA3605 support individual channel power disabling?

  Unused channels can be disabled within Sysmac Studio hardware settings to optimize internal processing and reduce power dissipation.

• How is cross-platform firmware flash compatibility handled?

  Sysmac Studio automatically checks and matches module revision codes against system controller firmware rules during project download.

• What happens to the analog output signal if backplane communication fails?

  Output behavior upon bus fault (such as hold last value or clear to 0 V) is configurable through the master controller settings.
