Product Overview

The Siemens 6ES7231-4HF32-0XB0 is a SIMATIC S7-1200 SM 1231 analog input signal module designed for analog signal acquisition in Siemens S7-1200 PLC systems. This module provides 8 differential analog input channels with a 12-bit plus sign-bit (13-bit ADC) resolution. It supports selectable voltage input ranges of ±10 V, ±5 V and ±2.5 V and industrial current input ranges of 0-20 mA and 4-20 mA. The module has a rated 24 V DC supply voltage and allows connection of compatible voltage and current analog field signals for processing within a SIMATIC S7-1200 system. The combined eight-channel design supports applications that require analog measurement and PLC-based process monitoring. The manufacturer's catalog currently lists this module as an active product, with a scheduled phase-out date of November 1, 2026. Supplied packaging photographs show the exact Siemens catalog number 6ES7231-4HF32-0XB0. The physical module nameplate has not yet been photographed. Confirm the input signal range, module hardware version, wiring method, power supply and S7-1200 system compatibility before installation.
