It handles RTDs (Pt100, Ni100, Pt1000, Ni1000 standard/climate), voltage (1-5 V), and current (0-20 mA). MSI and PTC inputs are built in—MSI powers 2-wire transmitters directly, PTC connects motor thermal protection without external relays. The module fits a standard S7-1500 slot: 35 mm wide, 147 mm tall, 129 mm deep. Status indication via green RUN LED and red ERROR LED.","metaTitle":"Siemens 6ES7531-7QF00-0AB0 Analog Input Module MSI PTC","metaDescription":"6ES7531-7QF00-0AB0 S7-1500 analog input module with MSI and PTC.
