Siemens 6ES7231-4HF32-0XB0

Product Description

Product Details

Core Function: Provides 8 high-precision analog input channels for measuring voltage (e.g., ±10V, 0-10V) and current (e.g., 0-20mA, 4-20mA) signals from field sensors.
Compatibility & Integration: Designed exclusively for the SIMATIC S7-1200 controller family. Modules are easily configured and programmed using Siemens TIA Portal (Totally Integrated Automation) software.
Electrical Characteristics: High resolution (16-bit) and accuracy across all channels. Supports differential inputs for improved noise rejection in electrically noisy environments.
Diagnostics & Monitoring: Comprehensive diagnostic capabilities including wire break detection, underflow/overflow monitoring, and module health status indicators for simplified maintenance.
Design & Connectivity: Compact design for space-efficient installation on the S7-1200 CPU right side. Features a removable front connector block for easy wiring.
Application Value: Essential for precise monitoring of process variables like temperature, pressure, flow, and level in applications such as water treatment, packaging machinery, and building automation.
