Siemens 6ES7531-7PF00-0AB0 is a SIMATIC S7-1500 SM 531 high-feature analog input module designated AI 8xU/R/RTD/TC HF. It provides eight channels in groups of one for voltage, resistance, RTD and thermocouple measurement. Siemens specifies 16-bit resolution, increasing to as much as 21 bits for RTD and thermocouple measurements, with 0.1% accuracy. The module supports diagnostics, hardware interrupts, a scalable temperature measuring range, thermocouple Type C and calibration in RUN. Common-mode voltage is specified as 30 V AC or 60 V DC. Delivery includes an infeed element, shield bracket and shield terminal, while the front connector is ordered separately.
