Product Description

The 6ES7231-7PB22-0XA0 is a compact S7-1200 analog module designed for precise signal acquisition in industrial automation. It provides 4-channel current/voltage input with a 16-bit resolution, supporting ranges of ±10 V, ±5 V, ±2.5 V, or 0–20 mA. Directly compatible with S7-1200 PLCs, it connects via a built-in backplane without requiring external cabling. The module operates at 24 V DC with a tolerance of 20.4–28.8 V DC and functions within -20°C to +60°C. Ideal for process industries like manufacturing, water treatment, and energy, it ensures high accuracy and fast sampling rates (up to 50 Hz per channel). Key advantages include easy configuration via TIA Portal software and robust noise immunity. Limitations include lack of intrinsic safety certifications for hazardous environments. The module does not include a display, battery, or sensor-specific interfaces, focusing solely on analog signal conditioning.
