Product Description

The Siemens 6ES7231-7PD22 is an 8-channel analog input (AI) module for the SIMATIC S7-200 PLC system, designed for industrial automation and process control applications. It provides high-precision voltage or current signal acquisition with a resolution of 12 bits, supporting input ranges of ±10 V, ±5 V, ±2.5 V, or 0/4-20 mA. The module operates on 24 VDC power with a voltage tolerance of 20.4-28.8 VDC and functions reliably in temperatures from 0°C to 55°C. Compatible with S7-200 CPUs, it enables seamless integration with digital modules via the system's expansion interface. Key advantages include compact design, high noise immunity, and straightforward configuration via STEP 7-Micro/WIN software. Limitations include lack of intrinsic safety certification for hazardous environments. Ideal for monitoring sensors and transmitters in manufacturing, energy, and machinery sectors.
