Siemens 6ES7 332-5HF00-0AB0 Digital Input Module for SIMATIC S7-300 accepts 24 V DC discrete signals from field devices, providing 16 inputs for reliable PLC logic with standard industrial response. Each input is PNP (positive logic), draws about 2–3 mA, and features LED indicators with optical/electrical isolation between the field signals and the PLC. Designed for PB-bus rack mounting in S7-300 systems, it is IP20 protected and supports interfacing sensors, switches, safety interlocks, and other discrete devices in manufacturing lines, conveyors, packaging, material handling, and building automation.
