Specification Conflicts & Clarifications
| Parameter | Conflict Source | Adopted Value | Rationale |
|---|---|---|---|
| Dimensions | 80×80×25 mm vs. larger enclosures | Module vs. system distinction | Core electronics modular; enclosures vary by site |
| IP Rating | IP20 vs. IP67 | IP67 (field) / IP20 (control) | describes I/O module; others field unit |
| Output Protocols | RS-485 only vs. HART/FF | HART/FF standard; RS-485 option | Multiple sources confirm multi-protocol support |
