SIEMENS - SIMATIC S7-1200 - Analog Input Modules

The Siemens SIMATIC S7-1200 SM 1231 Analog Input Modules provide precise analogue signal acquisition for industrial automation and process control applications. Designed for seamless integration with the SIMATIC S7-1200 PLC platform, these expansion modules support accurate measurement of voltage and current signals for monitoring sensors, transmitters and process instrumentation.

The SM 1231 range includes 4-channel and 8-channel analogue input modules, with standard 13-bit + sign and high-resolution 16-bit variants available. Configurable input ranges, integrated diagnostics, galvanic isolation and engineering through Siemens STEP 7 within TIA Portal make these modules suitable for manufacturing, water treatment, HVAC, OEM machinery, utilities and process automation.

The modules communicate via the SIMATIC S7-1200 backplane bus and are designed for reliable operation in industrial environments.
