5.3.3. Thermocouples
Thermocouples are usually polarized. To connect a thermocouple to the TC300, wire the positive lead to pin 4
(Sensor +), and the negative lead to pin 5 (Sensor -), as seen in Figure 7.

5.3.4. AD590
The TC300 also supports the AD590 temperature transducer. To connect an AD590 to the TC300, wire the positive
lead (anode) to pin 4 (Sensor +), and the negative lead (cathode) to pin 5 (Sensor -), as seen in Figure 8.

5.3.5. External Sensor Port
The TC300 also allows the user to connect a thermistor type of temperature via the “EXT. SENSOR” port on the
back panel. The EXT.SENSOR port accepts a 2.5 mm stereo earphone jack. It is directly compatible with the
Thorlabs TSP-TH temperature probe sensor.
