Lead — integrator note
The NX-AD4603 is an 8-channel analog voltage input module rated for 24 V supply. It mounts on DIN rail, operates from 0 to 55 °C, and carries CE, cULus, C-Tick, KC, Lloyd, NK approvals.
Delta — channel count vs. sibling NX-AD4203
This is not a second-source; the NX-AD4208 also offers 8 analog inputs, but its signal type (current vs. voltage) is not confirmed in the available spec, so assume different wiring unless you have the datasheet. Stick with the NX-AD4603 if your sensor loop requires voltage input.
Integration — panel checklist
Mount on DIN rail; spring terminals need no screw torque. Ambient 0–55 °C, bulk-packaged.
