Product Overview
The 6ES7231-4HF32-0XB0 is a SIMATIC S7-1200 analog input signal module (SM 1231-AI, 8 channels, 13-bit plus sign), designed to be mounted on the S7-1200 backplane. It acquires analog process signals in voltage (±10 V, ±5 V, ±2.5 V) or current (0-20 mA, 4-20 mA) formats at a cycle time up to 625 µs. This module integrates into standard automation systems for monitoring and control tasks requiring multiple precise analog inputs.
