Installation Guidelines

• Mounting: Snap the NX-AD2603 onto the NX-series I/O bus coupler or adjacent I/O units on a 35 mm DIN rail. Ensure the side connector is fully engaged to establish the internal bus communication.
• Wiring: Connect your analog sensors to the terminal block. Given the single-ended input method, ensure that the signal and the reference ground are properly connected to prevent ground loop noise.
• Input Protection: Although the module is rated for an absolute maximum of ±15 V, always use signal conditioners or surge protection if the field environment is subject to high-voltage spikes.
• Configuration: Use the Omron Sysmac Studio software to configure the scaling and filtering parameters of the input points to match your specific field sensor requirements.
