It reads Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni200, Ni500, Ni1000, and Cu10 — essentially the full roster of common platinum, nickel, and copper RTD curves. That covers most temperature sensing in industrial process lines without needing a separate converter per probe type. Power comes from the ET 200S backplane at 24 VDC — no separate field supply needed. The module draws 0.6 W typical, which keeps the thermal budget in a densely packed terminal block cluster manageable. It uses a sigma-delta integrating measurement principle, with a selectable integration time of 16.7 ms or 20 ms. The 20 ms setting rejects 50 Hz line noise cleanly; 16.7 ms handles 60 Hz. That matters when you are running RTD leads past VFDs or welding supplies in the same cabinet. ## Filtering, diagnostics, and cable reach Digital filtering is configurable in four stages: none (1× cycle time), low (4×), medium (32×), or high (64×). The high setting smooths a noisy signal but adds latency — fine for a slow thermal process, not for a fast-reacting temperature loop on a plastic extruder barrel. Diagnostics cover wire-break, overflow/underflow, and group error — each can be enabled or disabled independently. The group error is mapped to the red SF LED on the module face, so a glance at the rack tells you if any channel is faulted. Isolation between channels is not provided; the module is tested at 500 V DC between the I/O and the backplane. Maximum shielded cable length is 200 m. That is generous for a distributed I/O slice — you can reach a tank farm at the far end of the plant without a repeater, as long as the RTD leads are twisted-pair and grounded at one end. No isochronous mode — this module is not for time-synchronized motion axes. It is a straight temperature input slice for process and discrete manufacturing. No stock-holding claim; each order is verified against the BOM quantity.","metaTitle":"Siemens 6ES7134-4NB50-0AB0 RTD Module, 4-Channel, Active","metaDescription":"Siemens 6ES7134-4NB50-0AB0 ET 200S 4AI RTD module.
