    NEW UNOPENED BOX CONDITION

    SIEMENS 6ES7 321-1FH00-0AA0 SIMATIC DIGITAL INPUT + DIGITAL EINGABE MADE IN CHINA  is a robust digital input module + DIGITAL EINGABE specifically designed for the SIMATIC S7-300 automation system. This optically isolated module features 16 input channels arranged in groups of four, providing high-performance electrical separation between field signals and the PLC backplane bus. Engineered for 120/230 V AC applications, it operates within a frequency range of 47 to 63 Hz and recognizes a “0” signal between 0 and 40V AC, while a “1” signal is detected between 79 and 264V AC. For a “1” signal, the typical input current is 6.5 mA at 120 V (60 Hz) and 16 mA at 230 V (50 Hz), with a fixed input delay of 25 ms for both signal transitions.

    The module is highly compatible with industrial sensors, supporting standard switches and 2- or 3-wire AC proximity switches (BEROs). Installation is streamlined via a standard 20-pin front connector, and the unit is designed with a typical power loss of 4.9 W. Physically, the module is compact, measuring 40 mm x 125 mm x 117 mm (width x height x depth) and weighing approximately 240 g, making it an efficient choice for dense control cabinet configurations.
