The SIMATIC S7-1500 AI 8xU/I HS (6ES7531-7NF10-0AB0) is a high-speed analog input module from Siemens, designed for SIMATIC S7-1500 systems. \nThis module features 8 channels grouped in sets of 8, with 16-bit resolution and 0.3% accuracy. The common mode voltage is 10 V. It includes diagnostics, \nhardware interrupts, and oversampling (0.0625 ms) functions. Delivery includes an infeed element, shield bracket, and shield terminal, but the front connector \n(screw terminals or push-in) must be ordered separately. With a net weight of 0.419 kg and packaging dimensions of 16.10 x 19.30 x 4.70 cm, its compact design \nhelps save space in control cabinets. DIN rail mounting is supported. It is used in industrial automation systems, particularly for high-speed and high-precision processing of analog signals (voltage or current).
