The SCC-TC02 has a fixed screw-terminal receptacle and a removable 
screw-terminal block, as shown in Figure 2.

After you install the SCC-TC02, attach the input signals to the screw 
terminals of the module.

1.

Remove power from the signal lines.

2.

Strip 7 mm (0.28 in.) of insulation from the ends of the signal wires.

3.

Insert the wires into the screw terminals.

4.

Tighten the screws to 0.5 to 0.6 N

⋅ m (4.4 to 5.3 lb −  in.) of torque.

The SCC-TC02 accepts up to three signals: TC

+, TC–, and GND. TC+ is 

the positive thermocouple lead and TC– is the negative thermocouple lead.

The GND terminal connects to AIGND on the E Series DAQ device.

The SCC-TC0X has a 10 M

Ω bias resistor connected from the negative 

thermocouple input to ground. This resistor allows the thermocouple to be 
ground-referenced or floating without requiring external bias resistors 
connected to ground.

For ANSI color-coded J-type thermocouples, the red wire is negative and the white wire is positive. Refer to the thermocouple 

data sheet if possible. You can find information about other color-coding schemes in the NI KnowledgeBase at
