What it is and where it sits
The Omron NX-AD2604 is a 2-channel analog input module in the NX series, scaled for voltage signals on a 24V backplane and intended to populate a node on an NX I/O drop alongside NX-series digital and specialty modules. It is the voltage-input variant of the 2-channel analog sibling set, meaning it accepts analog voltage rather than current or thermocouple/RTD inputs — the signal-class call that has to be locked before the field wiring is landed.
Termination and mounting
Spring-terminal terminations take the field wiring — solid or ferruled conductors land cleanly under the clamp, and the cage-style connection shortens strip length and keeps the row legible after panel marking. DIN rail mounting places the module in a standard panel-builder footprint; the 0–55°C operating envelope covers most cabinet interiors, so the unit will sit comfortably next to adjacent NX digital and communications modules without thermal rearrangement.
Panel-room and compliance posture
Approval markings cover the usual multi-region build — CE, cULus, C-Tick, KC, Lloyd, and NK — so the same BOM line clears a European panel yard, a North American UL-Listed build, a Korean marine install, and a Lloyd/NK shipboard retrofit without a sub-variant on the part number.
Lifecycle and sourcing
No official successor appears in the active product record; any retirement of this code would follow a planned NX-platform migration rather than a per-module EOL notice.
