The Omron NX1W-ADB21 Machine Automation Controller Analog Input Option Board provides 2 analog input channels for voltage and current measurement. Voltage inputs support a 0 to 10 V range with 1/4000 resolution, while current inputs support 0 to 20 mA signals with 1/2000 resolution. This allows compatible sensors, transmitters, and measuring devices to provide analog values to the controller through the same option board. A screwless clamping terminal block provides the specified wiring interface. The NX1W-ADB21 adds compact analog measurement capability to compatible NX systems. Its mixed signal support complements the PLC analog input range within Omron machine automation applications.
