Important Notes

• The correct product designation is Proximitor I/O Module with Internal Terminations, not a generic interface module.

• This is a rear I/O module, not the main 3500/40M monitor card.

• Field wiring connects directly to the module's internal terminals.

• External termination blocks are not compatible with the internal-termination configuration.

• Confirm compatibility with the installed 3500/40M monitor and existing transducer configuration before ordering.

• Verify the exact part number, revision, and physical condition before installation.
