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.
