Frequently Asked Questions

Does this module support both 2-wire and 3-wire RTDs?
Yes. The NTR002-A supports standard 2-, 3-, and 4-wire RTD configurations with lead-wire compensation to maintain accuracy over long distances.

Is it compatible with legacy Bailey Infi 90 systems?
Generally yes. The module is backward compatible with many Infi 90 mounting units, though baseplate compatibility should be verified before installation.
