Product Precautions
Emerson KJ4001X1-CH1 12P1811X032 accommodates two-, three- and four-wire RTD arrangements at one removable terminal interface for temperature and resistance channels.
- Terminates eight resistance or RTD input circuits.
- Supports two-, three- and four-wire sensor connections.
- Preserves lead-compensation wiring at the terminal interface.
- Uses C3 keying with the matched RTD card.
KJ4001X1-CH1 12P1811X032 must remain matched to its documented system interface, mating hardware and controlled configuration.
Important Notice: Match the complete KJ4001X1-CH1 12P1811X032 marking and documented interfaces before installation, then verify the intended technical response.
