Omron NX-DA3603 NX Series Analog Output Unit 4 Channels ±10V 1/8000 250µs Push‑in

Omron NX‑DA3603 is a 4‑channel analog voltage output unit for the NX series I/O system. Each channel outputs a voltage signal in the range of –10 V to +10 V, with a resolution of 1/8000 (13‑bit). High‑speed conversion at 250 µs per channel supports precise actuator control, valve positioning, and speed references in machine automation and process control. The 12 mm wide, screwless push‑in terminal block ensures tool‑free wiring and high‑density mounting.

Applications:

• Speed reference for servo drives and variable frequency drives (VFDs)

• Positioning of proportional valves in hydraulic and pneumatic systems

• Analog control for SCR power controllers and electric actuators

• Signal simulation and test equipment interfacing

System Integration:

• This analog output unit belongs to the Omron NX series I/O system.

• Requires an NX series communication coupler unit (e.g., EtherCAT coupler NX‑ECC203 or EtherNet/IP coupler NX‑EIC202) for operation.

• Supports both free‑run refreshing and synchronous I/O refreshing when used with an EtherCAT coupler.

• Mounts on 35 mm DIN rail; connects to the NX bus via the communication coupler.
