Product details

RTD input coverage for temperature loops

The 6ES7331-7PF01-0AB0 is an S7-300 analog input module that reads resistance thermometers and resistive sensors directly — no external transmitters needed. 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.

Frequently asked questions

Is 6ES7331-7PF01-0AB0 compatible with S7-300?

Yes, it is an S7-300 analog input module — it snaps onto the standard DIN rail and connects to the backplane bus via the included bus connector. It fits any S7-300 rack that has a free slot.
