The SM 1231 analog input module for Siemens S7‑1200 PLCs provides 4 high-precision universal inputs, supporting both voltage (0–10 V) and current (4–20 mA) sensor signals. Designed for applications like temperature control, flow measurement, and level monitoring, it ensures accurate and reliable data acquisition with 16-bit resolution and excellent signal stability—even in noisy environments.
Compact and DIN-rail mountable, the module utilizes minimal panel space and features short-circuit protection, wire-break detection, and integrated diagnostics to support safe and maintainable operations. Configured directly through TIA Portal, setting up channel types, scaling, and fault handling is both intuitive and rapid. This plug-and-play design enables seamless compatibility with the S7‑1200 architecture, maintaining synchronized performance and communication.
Available from Scalar Automation in Kenya, this SM 1231 module is well-suited for OEM machines, water/wastewater systems, HVAC processes, and industrial monitoring networks looking for precise analog input performance in a compact and expandable control system.
