High-Speed Synchronous Control for Precision Automation
The Omron NX-OD5121 digital output unit delivers the speed you need. With a rapid 0.1 ms ON-response time, it ensures your equipment performs with precision.
This speed is perfect for applications requiring exact timing. When paired with an EtherCAT coupler unit, the NX-OD5121 supports synchronous refreshing. This means the digital outputs align perfectly with the controller’s scan cycle. This feature eliminates delays and guarantees your automation processes are perfectly coordinated.
Flexible I/O Configuration with NX-Series CPU and Coupler Units
The NX-OD5121 unit is designed to fit into any system architecture. It connects directly to an NX series CPU unit for a centralized control setup. It can also be used in a distributed I/O system with a communication coupler unit.
This versatility allows you to place I/O exactly where it’s needed. You can reduce wiring and simplify your machine design. As a part of the wide NX family, this digital unit works alongside other I-O units like the NX-ID, IA, OD, and OC models.
Simplified Installation with Push-In Terminals and DIN Rail Mounting
The NX-OD5121 unit uses Screwless Push-in Plus terminals. This technology allows you to connect wires quickly and securely with one simple action. No screws, no special tools, just a solid connection every time.
Reliable NPN Transistor Output for Demanding Digital Loads
The NX-OD5121 provides 16 points of robust NPN transistor digital output. Each point can drive a load of up to 0.5A, with a total capacity of 4A for the entire unit. This is more than enough power for a wide range of devices, such as indicators, small relays, and solenoid valves.
