Product Description

The Siemens 6ES7231-4HA30-0XB0 is an 8-channel analog input expansion module designed for the S7-200 PLC series. It supports voltage (±10 V) or current (0-20 mA) signals with a resolution of 12 bits, enabling precise data acquisition. The module connects directly to the S7-200 main unit via the system bus, requiring no additional interfaces. Operating at 24 VDC with a temperature range of 0–55°C, it is suited for industrial environments like manufacturing and process control. Compact and DIN-rail-mountable, it offers easy integration. However, it lacks onboard isolation and requires external signal conditioning for noisy environments. Battery capacity and screen features are not applicable, as it is a purely I/O expansion device. Its high accuracy and scalability make it ideal for systems needing reliable analog signal monitoring.
