4. Critical Notes & Contradictions
- Functional Mislabeling:
- Evidence incorrectly identifies the module as a “soft starter” (170A rating), conflicting with pulse counting functions described elsewhere. This is likely a documentation error.
- Evidence (motor drive) and (pressure sensor) describe unrelated products.
- Technical Discrepancies:
- Dimensions: Three conflicting size/weight combinations exist. The 328.5×238.5×18 mm/0.38 kg specification is most consistently cited .
- Protection Class: IP20 (indoor) vs. IP67 (dust/waterproof) . Industrial applications typically require IP67, but ABB documentation varies.
- Product Status:
The module is discontinued (“Stop production”) and marked sold out , affecting procurement.
