Procurement managers rarely finalize NX1W-ADB21 without reviewing Siemens PLC, Omron Photoelectric Sensor and Nx1P2 1040Dt1, ensuring that the chosen component meets budget, compliance, and delivery conditions.
Omron NX1W-ADB21 Machine Automation Controller
The Omron NX1W-ADB21 Machine Automation Controller is a precise Analog Input Option Board featuring two analog input channels for 0–10 V voltage signals with 1/4,000 resolution and 0–20 mA current input with 1/2,000 resolution. Using a screwless clamping terminal block, it provides stable signal capture for sensors, transmitters, and measurement devices. Designed for high-accuracy analog monitoring inside NX1P2 systems, it ensures fast conversion and reliable data integrity. Manufactured by Omron, part of the Omron Programmable Logic Controller (PLC) product family under the Omron NX Series.
