The Omron NX-DA3603 Machine Automation Controller Analog Output Unit provides 4 voltage output channels, each supporting a -10 to +10 V output range. Each channel operates with 1/8000 resolution and ±0.3% overall accuracy for reliable analog signal generation. A 250 μs per-point conversion time supports regular output updates, while Free-Run refreshing maintains continuous operation. With 4 output channels in one module, the NX-DA3603 expands the analog output capacity of an NX control system. It can be combined with other PLC analog expansion modules within Omron machine control systems.
