Description
The Siemens 6ES7331-7PF01-0AB0 is an eight-channel SM 331 module for resistance thermometers and resistance. Siemens describes it for Pt100/200/1000, Ni100/120/200/500/1000 and Cu10 sensors in 2-, 3- or 4-wire connection, with 16-bit resolution and a 40-pin front connector. Siemens's data sheet marks it as a spare part. Siemens names no direct successor for the order number; its route forward is migration to the S7-1500 with ET 200MP.
Application: Analog I/O module
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7331-7PF01-0AB0 used for?
It measures temperatures from RTD sensors in process plant, ovens and HVAC, eight channels per module.
Key features
- 8 inputs for resistance thermometers and resistance
- Pt100/200/1000, Ni100/120/200/500/1000, Cu10
- 2-, 3- or 4-wire connection
- 16-bit resolution
- Isolated; 40-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7331-7PF01-0AB0 discontinued?
Yes. Its manufacturer lifecycle status is Discontinued.
Can another Siemens SIMATIC S7-300 part replace it?
Potential replacements must be checked against the required ratings, dimensions and connections. Sharing a family name does not establish interchangeability.
Do you ship worldwide?
Yes. TimControls ships worldwide. Parts usually ship within 3 to 7 working days of order confirmation, and the exact lead time and shipping options are stated on your quote. Include your delivery country and postal code when you ask for a quote.
