Description:
The Siemens 6ES7321‑1BL00‑0AA0 is an 8‑channel Digital Input Module (SM 321) for the SIMATIC S7‑300 PLC, designed to receive and process discrete 24 V DC field signals with positive‑logic (PNP) inputs. Mounted on a PB‑bus rack in S7‑300 systems, it provides LED indicators for each input, draws about 3 mA per channel, and is IP20 protected with standard industrial response times. Used to interface sensors, switches, pushbuttons, and safety devices in manufacturing lines, conveyors, packaging, and material handling, it captures 24 V DC field states and transmits them to the PLC for control sequencing, status monitoring, and safety interlocks.
