The SM 1231 RTD (6ES7231‑5PD32‑0XB0) is a high-precision 2-channel analog input module designed for Siemens S7‑1200 PLC systems, specifically optimized for resistance temperature detectors (RTDs) such as Pt100 and Pt500. Housed in a compact footprint, this module provides accurate and stable temperature monitoring, making it ideal for process industries, HVAC systems, and equipment requiring reliable thermal control.
Each channel supports both 2-wire and 3-wire RTD wiring, with built-in cold-junction compensation and fault detection, allowing detection of broken wires or sensor faults. The 16-bit resolution ensures precise temperature readings, while LED status indicators offer clear, on-board diagnostic feedback. Seamless mounting on the S7‑1200 rail and direct backplane connection simplify installation and system integration without the need for external signal conditioning.
Engineered for real-time control, the SM 1231 RTD exchanges data efficiently with the CPU over PROFINET. Configuration via TIA Portal allows engineers to easily set up scaling, input limits, and device monitoring within the automation project. Distributed by Scalar Automation in Kenya, this module provides high-accuracy temperature measurement in a reliable and scalable format, making it a smart choice for engineers building compact yet flexible control systems.
