Transmitters - In Head Style, Wiring - Isolated Transmitter - TSI

Transmitter Wiring - TSI Types The typical wiring for the TSI series transmitters is shown below. The system would include a transmitter, power supply and digital instrument. If you have any difficulties with setting up your transmitter, our sales engineers are available to provide technical support. RTDs may have different color coding than our standard Black, Black, Red, and Red. As a general rule, for 3 wire RTDs, connect two of the like colors to terminal #1 and #2 and one of the second colors to terminal #3 (The remaining wire can be cut off or taped back). For 4 wire RTDs, connect the second two like color wires to terminals #3 and #4. To connect the transmitter to your instrument and power supply, use our part number 20I02-PP-S (see page 169) and attach the instrument wire on terminals #5 and #6. Note: When wiring your transmitter the NEGATIVE wire of a thermocouple is always coded RED.
