Analogue Module 2AQ

The Siemens 6ES7332-5HB01-0AB0 is an analogue output module (SM 332) for the SIMATIC S7-300 series, designed to provide reliable and precise analogue signal output for industrial automation applications. This module features two isolated analogue outputs, supporting both voltage and current signals, and is hot-swappable with the S7-300 backplane bus active.
