Product details

SIPLUS SM 331 AI Overview

The Siemens 6AG1331-1KF02-4AB0 is a SIPLUS analog input module for the S7-300 rack, rated for 0 to 60 °C ambient and carrying CE, FM, KC, and UL approvals. It reads resistance temperature sensors (Pt100, Ni100, Ni1000, LG-Ni1000) and analog signals (0-20 mA, 0-10 V, 1-5 V) across eight channels, fitting the 40 mm wide S7-300 footprint.

Temperature and Signal Ranges

Operating range spans 0 °C to 60 °C, wider than standard S7-300 AI modules; suited for unheated control cabinets or near-process heat. RTD support covers Pt100, Ni100, Ni1000 (standard/climate) and LG-Ni1000; no thermocouple types are supported. Voltage inputs include 0-10 V and 1-5 V; current inputs include 0-20 mA, plus a resistance measurement mode.

Certification and Mounting

CE, FM (CofC 3028431), KC, and UL (File E239877) marks simplify compliance for installations requiring North American or Korean approvals. The module occupies a 40 mm wide slot on the S7-300 mounting rail; depth is 117 mm including the backplane bus connector.

Frequently asked questions

What is the operating temperature range of 6AG1331-1KF02-4AB0?
