A triad would only provide you with three wires/conductors/cores, and a properly-applied 4-wire RTD requires 4 (four) wires/conductors/cores. You could use two (2) two-wire (conductors; cores) twisted, shielded pair cables for a total of four wires/conductors/cores--which is what should be used for a 4-wire RTD.
