Product Description

Siemens SIMATIC S7-1200 Analog Input Module

The Siemens 6ES7231-4HF32-0XB0 is a high-precision 8-channel Analog Input Module for the SIMATIC S7-1200 series, designed as an expansion module for compact and scalable automation solutions. This high-end configuration offers superior resolution and flexibility, supporting voltage, current, resistance (RTD), and temperature (Thermocouple) signals directly without external signal conditioners.

Key Features & Benefits

Ultra-High Precision Acquisition

25-bit Sigma-Delta ADC delivers exceptional measurement precision (±0.1% of full scale typical)
Up to 16-bit + sign bit effective resolution for fine signal granularity
Fast sampling capability: scans all 8 channels in as little as 250 µs

Universal Signal Compatibility

Software-configurable inputs for voltage, current, or temperature sensors
Voltage ranges: ±10V, ±5V, ±2.5V, 0-10V
Current ranges: 0-20mA, 4-20mA (with open-circuit detection)
RTD support: Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000 (2/3-wire)
Thermocouple support: Type J, K, T, E, R, S, B, N with integrated cold junction compensation

Robustness & Reliability

Galvanic isolation: 500 VDC channel-to-channel and channel-to-backplane
Overvoltage protection up to ±35 V DC
Conformal coating protects against dust, moisture, and corrosive gases

Advanced Diagnostics & Usability

Channel-level diagnostics for wire breaks, short circuits, and out-of-range values
LED status indicators for RUN and ERROR conditions
Seamless integration with S7-1200 CPU via expansion bus
