Siemens Modules 6ES7231-4HF32-0XB0

The Siemens 6ES7231-4HF32-0XB0 module is an SM 1231 analog input module for the SIMATIC S7-1200 PLC series, designed to measure voltage and current signals from external sensors. 

Specification:

• Module Type: Analog Input Module (SM 1231).
• Compatibility: Specifically designed for use with the SIMATIC S7-1200 Programmable Logic Controller (PLC) series.
• Number of Inputs: Features 8 analog inputs (8 AI).
• Input Ranges: Supports various selectable input ranges:
  • Voltage: +/-10 V, +/-5 V, +/-2.5 V.
  • Current: 0-20 mA or 4-20 mA.
  • Resolution: Offers high precision with a resolution of 12 bits plus sign (12 bit+sign) or equivalent to 13-bit ADC (Analog-to-Digital Converter).
  • Supply Voltage: The rated value (DC) is 24 V.
  • Current Consumption: Typically 45 mA from the 24V DC supply and 90 mA from the 5 V DC backplane bus.
  • Power Loss: Typical power loss is 1.5 W.
  • Isolation: The unit is optically isolated, which improves anti-interference stability.
  • Application: Ideal for industrial automation, process control, and PLC programming applications that require accurate analog data acquisition.
