It supports Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni200, Ni500, Ni1000, LG-Ni1000, and Cu10, covering the common platinum and nickel curves used in industrial temperature monitoring. For resistive sensors without a standard curve, it also measures straight resistance in three ranges: 0 to 150 ohms, 0 to 300 ohms, and 0 to 600 ohms. ## Panel fit and wiring constraints The module is 40 mm wide, 125 mm high, and 120 mm deep — it occupies one slot in an S7-300 rail and leaves clearance for the front connector and wiring duct. The depth includes the bus connector overhang; plan for 120 mm behind the panel door. This module is a mature S7-300 design.","metaTitle":"Siemens 6ES7331-7PF01-0AB0 Analog Input Module","metaDescription":"Siemens 6ES7331-7PF01-0AB0 analog input module for S7-300.
