– Compatibility & Integration
Designed exclusively for integration with National Instruments FieldPoint terminal bases (FP-TB-x series). This module connects via dedicated screw terminals and does not interface with FP-TB-10 terminal base screw terminals. Optimized specifically for PT100 RTD sensors; alternative FieldPoint RTD modules support different sensor types and configurations such as 2-wire, 4-wire, or PT1000 variants.
