Product details

The NXRS1201: The module fits a 12 mm DIN-rail footprint with a removable screwless push-in terminal block (16 terminals). Conversion cycle runs at 125 µs per sample, configurable for free-running, synchronous, or task-period-prioritized refresh.

24-bit resolution on a ±5 mV/V input range. The differential input circuit rejects common-mode noise from long cable runs; with a ±0.1 µV/°C RTI zero drift, long-term stability holds without frequent tare recalibration.

Integration note

Mounts on a DIN rail; width 12 mm leaves room for adjacent NX slices. The removable screwless terminal block has 16 terminals and pulls out without depopulating the rail. Requires an NX-PF power supply unit on the bus; the module itself draws backplane power only (no external 24 V needed). IP20 enclosure suits clean indoor panels. After mounting, allow a 30-minute warm-up before taking critical readings; the rated drift specifications assume thermal equilibrium.

Frequently asked questions

What is the alternate order code for the NXRS1201?

The NXRS1201 is also listed under the code NX-RS1201. Both refer to the same load cell input module.

Can the NXRS1201 replace an NX-RS1201 in an existing panel without rewiring?

Yes, they are the same module; the NX-RS1201 is simply an alternate MPN. No rewiring or configuration changes are needed.
