Chapter 3: Connections

Overview

This chapter will discuss the connections required to operate the TCDA thermocouple amplifier. Connections between the A/D converter and the TCDA should be kept as short as possible.

Thermocouple Connections

The TCDA can amplify voltage from a K-type thermocouple. Only one thermocouple can be connected to each channel. The thermocouple connections are made using terminal blocks. The positive (+) lead of the thermocouple must be connected to T1+ and the negative (-) lead to T1- (T2+ and T2- for channel 2). Make sure that both leads of the thermocouple are connected to the same channel. Color coding is used to designate the thermocouple’s polarity. A K-type thermocouple’s negative lead is red, and the positive lead is yellow. Figure 3.1 shows the thermocouple connections.

Power Supply Connections

A 2.5mm power jack is provided on the side of the TCDA hood. A 12VDC power supply must be connected to the 2.5mm power jack. The 232PS is recommended (not included).

Output Connections

The amplified voltage of the thermocouple is available through a male DB-25P connector. This connector is pin compatible with B&B Electronics’ ADIO12 and SDAXX line of data acquisition modules. The FBDA can also be used with the SPDA data acquisition modules. The pinout of the TCDA is shown if Table 3.1. Figure 3.1 shows the connections required for the TCDA module.
