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.

Applicable Wires
Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching ferrules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tool are given in the following table.

* Some AWG 14 wires exceed 2.0 mm2 and cannot be used in the screwless clamping terminal block.
When you use any ferrules other than those in the above table, crimp them to the twisted wires so that the following processed dimensions are
achieved.
