NX-DA3603 4-Channel Analog Output Unit ±10V 1/8000 12mm | Omron

The Original New Omron NX-DA3603 is a 4-channel analog output unit for the NX series I/O system, designed for precise voltage output control in industrial automation and machine control applications. It provides four analog outputs with a ±10 V range, 1/8000 (13‑bit) resolution, and a fast 250 µs per channel conversion time. The 12 mm slim form factor, screwless push-in terminal block, and Free-Run refreshing method ensure high-density panel mounting and easy installation. Part of the NX series for EtherCAT communication coupler systems.
