Siemens 6ES7531-7KF00-0AB0 AI 8xU/I/RTD/TC ST is an eight‑channel analog input module designed for SIMATIC S7-1500 that accepts voltage, current, RTD, and thermocouple signals with 16‑bit resolution. It provides a 10 V common‑mode range, supports up to four RTD channels, and offers diagnostics and hardware interrupts to monitor channel status. The module is powered from 24 V DC and typically draws about 240 mA; delivery includes the infeed element, shield bracket, and shield terminal, with front connectors (screw terminals or Push‑In) ordered separately. Operating temperature range is −25 to +60 °C.
