Features:
- Direct termination: Connects 32 field loops at the Trident analog input baseplate.
- 3351 module pairing: Carries the active and hot-spare analog input module positions.
- Power-path visibility: Documents two field-power inputs with loop returns and shields.
The baseplate is the physical boundary between field-loop wiring and the plug-in analog input modules.
Active and spare positions should remain aligned with module keying and the saved point configuration.
Terminal and power-path photographs are valuable evidence because the baseplate part number alone does not show field assignments.

Important Notice: Manuals and supporting documents are provided for identification and engineering review. Confirm the complete product code before ordering.
- Primary position: Keep the active 3351 module identity and channel record together.
- Spare position: Retain the hot-spare relationship and correct mechanical keying.
- Baseplate boundary: Do not substitute an external-termination architecture by appearance.
- Identity evidence: Retain the 7400210-010 and AI 2351 markings with the Model 2351 service record.
- Channel map: Associate every terminal with its 4–20 mA loop tag.
- Polarity and return: Preserve transmitter polarity and documented return paths.
- Shielding: Maintain the approved shield treatment at the baseplate.
- Loop baseline: Record representative loop currents before rewiring when the approved procedure permits.
- Dual feeds: Record both field-power sources and protective devices.
- Common symptoms: Trace shared power and return paths when several loops drift together.
- Module comparison: Use active/spare diagnostics to isolate module and baseplate behavior.
- Trident analog inputs: Terminates 32 process-current loops for a 3351 module pair.
- Hot-spare service: Supports continuity planning with an active and spare input module.
- Legacy panel support: Provides an exact baseplate reference for Trident maintenance projects.
