The Siemens 6AG1331-7PF01-4AB0 is an RTD input module rated for an ambient range of -40 to 70 °C. It reads Pt100, Pt1000, Ni100, Ni1000, Cu10, and other RTD types, but does not support thermocouples — check the sensor type before wiring.
Width 40 mm, depth 120 mm, height 125 mm — mounts in a standard rack slot over the DIN rail. Backplane bus provides power; no external supply needed for the module itself.
CE, UL (File E239877), and KC approvals simplify panel certification for global projects.
The module is rated for -40 to 70 °C ambient.
CE mark, UL approval (File E239877), and KC approval are listed.
