Description
The Siemens 6ES7331-7NF00-0AB0 is an eight-channel, 16-bit SM 331 analog input module for voltage and current. Siemens's data sheet lists ranges of ±5 V, ±10 V, 1-5 V, ±20 mA and 0/4-20 mA, integration times of 10, 16.67, 20 or 100 ms, 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 6ES7331-7NF00-0AB0 used for?
It measures standard process signals where higher resolution matters, such as flow, level and weight transmitters.
Key features
- 8 analog inputs: ±5 V, ±10 V, 1-5 V, ±20 mA, 0-20 mA, 4-20 mA
- 16-bit resolution
- Integration time selectable: 10, 16.67, 20 or 100 ms
- Isolated; 40-pin front connector
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7331-7NF00-0AB0 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.
