Omron NX-OD2258 | Omron | NX-series Digital Transistor Output Unit

Description

The NX-OD2258 is a high-speed digital transistor output unit within the NX-series I/O system, designed for precision control applications requiring exact signal timing. This module features 2 digital outputs with PNP transistor configuration, capable of switching up to 0.5 A per point at a voltage range of 15.0 to 28.8 VDC. Engineered for high-speed performance, the NX-OD2258 supports Timestamp signal processing, allowing for precise output triggering synchronized with the EtherCAT network cycle. The unit utilizes a screwless push-in connector for efficient wiring and is housed in a slim 12 mm wide enclosure, making it ideal for compact, high-density I/O configurations.

Installation Guidelines

• Mounting: Ensure the module is properly clicked into the NX-series I/O bus connector on the DIN rail. Confirm the release lever is fully engaged.
• Wiring: Utilize the screwless push-in connection system. Strip wires to the recommended length (typically 8–10 mm) and insert directly. Use a flat-blade screwdriver to release wires when necessary.
• Grounding: Maintain the integrity of the functional ground connected to the NX-series system to ensure optimal noise immunity.
• Synchronization: When using the Timestamp feature, ensure the controller/master is correctly configured for distributed clock (DC) synchronization to realize the benefits of high-speed timing.
