Replaces / Drop-In Replacement For
The 3051CD2A02A1AS5M5 is a variant configuration within the Rosemount 3051CD coplanar family. It directly replaces other 3051CD models with matching flange codes (2A), isolation codes (02), and electrical configurations (AS5M5). Verify full part number alignment with your system documentation before ordering. Older Rosemount 3051 (non-coplanar) and 3051T models may require adapter manifolds.
Works With
- 4-20 mA HART field communicators for configuration and diagnostics
- Emerson Rosemount Instrument Toolkit software for transmitter setup
- WirelessHART mesh networks (with optional conversion kit)
- FOUNDATION Fieldbus and PROFIBUS protocol adapters
- Standard transmitter mounting brackets and installation hardware
