Product details

The 6AG1231-5PD30-2XB0: 4-channel analog input module for resistance thermometers (RTDs), part of the Siemens SIPLUS S7-1200 family. Supports Pt100, Pt1000, Ni100, Ni1000, Cu10, and other common RTD types. Power loss is 1.5 W typical. The module requires a front connector (not included).

Integration

Width 45 mm, height 100 mm, depth 75 mm — fits a single S7-1200 slot. IP20 rated; suitable for clean, dry control cabinets. The integrating measurement principle means the input filters out high-frequency noise, but settling time per channel needs to be accounted for in scan-cycle planning. Diagnostics function can be read out via the backplane. Diagnostic alarm and input status bits are available — useful for wire-break detection on long RTD runs.

Frequently asked questions
