NX-series Analog Input Unit NX-AD CSM_NX-AD_DS_E_2_5 Analog Inputs to meet all machine control needs; from generalpurpose inputs to high-speed synchronous, high-resolution units • Analog Input Units for the NX-series modular I/O system. • Connect to other NX-series I/O Units and EtherCAT Coupler units using the high-speed NX-bus. • Separate modules for voltage- and current inputs. Features • • • • • • • Up to eight analog inputs per unit. Free-Run refreshing or Synchronous I/O refreshing, can be selected for refreshing with the NX-series EtherCAT Coupler. Input update cycles of 10μs per channel, and a resolution of 1/30000, ideal for high-speed measurement and, high-precision control. All basic models are available as single-ended and differential-input types. The screwless terminal block is detachable for easy commissioning and maintenance. Screwless push-in terminal block significantly reduces wiring work. All models are just 12 mm wide, saving space in your cabinet.
