Description

The 6ES7231-0HC22-0XA0 is an 8-channel analog input module designed for integration with Siemens S7-1200 PLCs. Each input supports configurable signal types including 0–10 V, ±10 V, 0–20 mA, and 4–20 mA, with 12-bit resolution, allowing precise measurement of industrial analog signals. This module is ideal for connecting a wide range of sensors and transmitters that output analog values, such as temperature, pressure, flow, or level sensors. With the capability to handle both unipolar and bipolar voltage signals, it offers flexibility for use in both simple and advanced analog monitoring tasks. Each channel can be individually configured through the TIA Portal, enabling tailored setups for mixed signal environments. The high density of 8 inputs in a single module helps minimize cabinet space and wiring complexity. Its isolation between channels improves reliability in electrically noisy environments. The module is well-suited for process control systems, HVAC monitoring, and energy management applications where accurate analog data acquisition is essential.
