Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The Siemens 6ES7231-4HD32-0XB0 is an SM 1231 analog input module for the SIMATIC S7-1200 series, providing four differential analog input channels with ±10 V, ±5 V, ±2.5 V voltage ranges and 0-20 mA or 4-20 mA current ranges. It interfaces with S7-1200 controllers via the backplane bus, delivering 12-bit plus sign resolution (13-bit ADC) per channel. It is typically used to acquire analog process signals such as sensor outputs or industrial transducers in mid-level control systems.
Best Suited For
- Acquiring differential analog signals in S7-1200 systems
- Industrial process monitoring (e.g. temperature, pressure, flow via transducers)
- Migration or expansion of existing S7-1200 installations
- Compact control panels requiring analog measurement
