NX-OD5256-1 | Omron | Unité d'E/S numérique série NX

Description

Designed for seamless integration within high-speed Sysmac automation platforms, the NX-OD5256-1 serves as a high-density digital output module featuring 16 transistor outputs. This unit enables precise control over field actuators by delivering reliable switching performance synchronized with the machine controller's execution cycle. Operating on a 24 VDC rated voltage, the module utilizes PNP (source) logic and features built-in load short-circuit protection to safeguard system electronics against field-side electrical faults.

The unit supports advanced synchronization capabilities, allowing for both Free-Run and Synchronous I/O refreshing. Field connections are secured via a rugged, detachable M3 screw terminal block, which facilitates easy installation and maintenance. Designed for mounting on a standard DIN rail, this module connects directly to NX-series Bus Couplers for EtherCAT or EtherNet/IP, making it highly compatible with modern distributed control architectures.

Installation Guidelines

Ensure the following engineering practices are observed during the installation of the module:

• Mounting: Mount the module securely onto a 35 mm DIN rail inside a protective industrial enclosure. Verify the DIN rail is properly grounded.
• Wiring: Turn off all power supplies before connecting or disconnecting the M3 screw terminal block to prevent electrical shock or equipment damage.
• Heat Dissipation: Maintain recommended clearances above and below the NX-series unit stack to ensure natural convection cooling. Do not block the ventilation holes.
• Shielding and Noise: Route DC control lines separate from high-voltage AC power lines to minimize electromagnetic interference.

Compliance and Certifications

• CE Mark
• UL Listed (cULus)
