For high-speed, precise voltage data acquisition within Sysmac automation architectures, the Omron NX-AD3608 provides four channels of high-resolution differential analog inputs. This unit integrates seamlessly into the NX-series I/O system, offering an exceptional resolution of 1/30000 and an ultra-fast conversion speed of 10 microseconds per point. Designed to process voltage signals from -10 to +10 VDC, it supports both synchronous I/O refreshing and free-run refreshing modes, ensuring precise synchronization with the host CPU or EtherCAT coupler unit. Secure, vibration-proof field wiring is achieved through the integrated 12-terminal screwless Push-In Plus terminal block.

The NX-AD3608 is part of the Omron Sysmac ecosystem. When planning migrations or additions, ensure your NX1P2, NX102, or NJ-series CPU unit is running compatible firmware supporting high-speed synchronous I/O. Note that synchronous refreshing is only functional when this module is mounted adjacent to a CPU or an EtherCAT coupler (such as the NX-ECC203) that natively supports distributed clocks (DC).
Because this module utilizes a differential input design without inter-channel isolation, all negative terminal connections (V1- through V4-) must remain within the common-mode voltage range. If there is a high potential difference between your signal source grounds, ground-loop current will flow, causing severe measurement errors or eventual hardware failure. Ensure that the signal sources are either completely floating or tied to a single common reference point before entering the module.
To protect the highly sensitive 1/30000 resolution, always use high-quality shielded twisted-pair (STP) cabling for all analog lines. Ground the cable shields at a single point on the functional ground bar of your control panel. For maximum noise immunity, route the analog signal cables in a dedicated wire duct isolated from three-phase power lines and variable frequency drive (VFD) output cables.
CRITICAL WARNING
Disconnect all power sources to the NX Unit, CPU Unit, and any external I/O power lines before installing, removing, or wiring the module. Failing to completely de-energize the assembly can cause immediate equipment damage or unpredictable system behavior during commissioning.
Mount the NX-AD3608 onto the DIN rail by sliding the unit's guide hook firmly into place until you hear a solid click indicating that the slide lock has engaged.
Push the terminal block straight onto the front of the module until it locks securely into position. Check the mechanical alignment of the keys.
Prepare your solid wire or ferruled stranded wire, then insert it straight into the terminal hole. No screwdriver is required for standard Push-In Plus terminal operation.
Verify connection status using the Sysmac Studio software, observing the TS indicator LED state. A solid green light indicates normal communication and module health.
