What it is and where it's used
The 6ES7321-1BL00-0AA0 is a Siemens i/o module from the SIMATIC S7-300 / ET 200M range. Typical applications: Machine control panels, sensor and switch inputs. The manufacturer is phasing this part out, so supply from new is getting harder.
What to check before ordering
- Needs a 40-pole front connector, ordered separately.
- Not all 32 inputs are usable above 40 C (16 up to 60 C).
- The full part number, including the version suffix (for example -0AB0), because hardware revisions differ in firmware and features
- CPU firmware version, since some programs require a minimum version
