MTL 5582 / MTL5582 Single-Channel RTD Resistance Isolator

MTL Instruments MTL5582 / MTL 5582 single-channel resistance isolator for repeating RTD signals. Additional recorded reference: 144-8687.

Source features include selectable 2-, 3- or 4-wire RTD input (factory setting recorded as 3-wire), independently configured 2-, 3- or 4-wire output, and a green power indicator. Not suitable for multiplexed input cards.

The detailed source specifications below describe the RTD’s hazardous-area location, not approval to install the isolator itself in that location. Verify the exact unit documentation and installation requirements before use. The source uses “O”/“mO” resistance notation, retained in the table.
