Product details

Sibling NX-TS2101 is the same module but with only 2 analog inputs. Your BOM calls for four TC channels? NX-TS3101 saves a slot and a bus connection. Mechanically identical — same DIN footprint, same spring terminals, same bus connector. Swapping a 2-input panel for the 4-input unit means you gain two spare channels; no rewiring needed on the existing thermocouple pairs.

Mounts on standard DIN rail, termination via spring clamp (no screw tightening). Bus power and communication through the NX backplane connector; no separate loop supply needed. Rated 0°C to 55°C ambient, so keep it out of hot cabinet zones above motor starters. Approvals include CE, cULus, C-Tick, KC, Lloyd, NK — covers most project certification gates.

Frequently asked questions

What's the difference between NX-TS3101 and NX-TS2101?

NX-TS3101 has 4 analog thermocouple inputs; NX-TS2101 has 2. Both support the same thermocouple types and share the same physical form factor, DIN rail mount, and spring terminals.

Will NX-TS3101 drop into a panel wired for NX-TS2101 without rewiring?

Yes. Both modules share the same NX-series bus connection, DIN rail slot dimensions, and termination style. You can swap them without changing wiring for the existing thermocouple pairs; the extra channels remain available for future expansion.
