NX-series Analog I/O Units User’s Manual for Analog Input Units and Analog Output Units (W522)
Warnings
WARNING
During Power Supply
Do not touch the terminal section while power is ON.
Electric shock may occur.
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in Units that supply power while power is supplied or immediately after power is turned OFF. Touching any of these parts may result in
electric shock. There are sharp parts inside the Unit that may cause injury.
Safety Precautions
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnormality
occurs due to malfunction of the CPU Unit, Industrial PC, other Units, or slaves or due to
other external factors affecting operation.
Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must
be provided in external control circuits.
The CPU Unit or Industrial PC will turn OFF all outputs from Output Units in the following
cases. The remote I/O slaves will operate according to the settings in the slaves.
• If a power supply error occurs.
• If the power supply connection becomes faulty.
• If a CPU watchdog timer error or CPU reset occurs.
• If a Controller error in the major fault level occurs.
• While the CPU Unit is on standby until RUN mode is entered after the power is turned ON
External safety measures must be provided to ensure safe operation of the system in such
cases.
The outputs may remain ON or OFF due to deposition or burning of the output relays or
destruction of the output transistors. As a countermeasure for such problems, external
safety measures must be provided to ensure safe operation of the system.
If external power supplies for slaves or other devices are overloaded or short-circuited, the
voltage will drop, outputs will turn OFF, and the system may be unable to read inputs. Provide external safety measures in control with monitoring of external power supply voltage
as required so that the system operates safely in such a case.
You must take fail-safe measures to ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines, momentary power interruptions, or other
causes.
Not doing so may result in serious accidents due to incorrect operation.

Voltage and Current Inputs
Make sure that the voltages and currents that are input to the Units and slaves are within
the specified ranges.
Inputting voltages or currents that are outside of the specified ranges may cause accidents
or fire.
Transferring
Always confirm safety at the destination node before you transfer Unit configuration information, parameters, settings, or other data from tools such as the Sysmac Studio.
The devices or machines may operate unexpectedly, regardless of the operating mode of
the Controller.
Cautions
Wiring
When you connect a computer or other peripheral device to a Communications Coupler
Unit that has a non-isolated DC power supply, either ground the 0-V side of the external
power supply (i.e. Unit power supply) or do not ground it at all.
If the peripheral devices are grounded incorrectly, the external power supply (i.e. Unit
power supply) may be short-circuited.
Never ground the 24-V side of the power supply, as shown in the following figure.
14
Be sure that all terminal screws and cable connector screws are tightened to the torque
specified in the relevant manuals. The loose screws may result in fire or malfunction.
NX-series Analog I/O Units User’s Manual for Analog Input Units and Analog Output Units (W522)

they can be more easily built into other devices or the overall machine. The actual products have
been checked for conformity to EMC standards.*1
Whether the products conform to the standards in the system used by the customer, however, must
be checked by the customer. EMC-related performance of the OMRON devices that comply with EU
Directives will vary depending on the configuration, wiring, and other conditions of the equipment or
control panel on which the OMRON devices are installed. The customer must, therefore, perform
the final check to confirm that devices and the overall machine conform to EMC standards.
*1. Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2
EMI (Electromagnetic Interference): EN 61131-2 (Radiated emission: 10-m regulations).
