Product Overview

The 6ES7331-1KF00-0AB0 is a SIMATIC S7-300 analog input module (SM 331) providing eight isolated analog input channels with 13-bit resolution. It integrates into the S7-300 rack via a 40-pole backplane connector. Designed for measuring voltage, current, resistance, and RTDs such as Pt100, Ni100, Ni1000, and LG-Ni1000, it features a ~66 ms conversion time per channel. Typical uses include process data acquisition, sensor integration, and temperature/resistance monitoring in industrial automation systems. The 6ES7331-1KF00-0AB0 follows platform consistency with the later 1KF02 model.
