Features

• Heating from 20 °C to 200 °C
• User-Selectable Display Units (°F, °C, or K)
• Run Standalone or via Software
• Adjustable PID
• Compatible with Positive and Negative Temperature Coefficient Thermistors

The TC200 Heater Controller is a benchtop controller intended for use with resistive heating elements rated up to 18 W. This general-purpose instrument can drive various types of heaters, including foil (HT10K) and resistive coil (HT15W) types.

The unit accepts feedback from either positive (TH100PT) or negative (TH10K) temperature coefficient thermistors, has programmable P, I, and D gains, and will display the temperature in either °F, °C, or K. In addition, the TC200 can be programmed for up to five sequential temperature settings along with associated ramp and hold times for each level.

A user programmable maximum temperature limit provides protection to the device being heated and a user-programmable power limit protects the heating element from being over driven. Other safety features include an Open Sensor Alarm that will shut down the driver if the temperature sensing element is missing or becomes disconnected.

Capable of stand-alone operation from a simple keypad interface, the TC200 can be interfaced with a PC using a standard USB Type B connector and our TC200 Application Program, shown in the image to the right. Interfacing with a PC can also be achieved by using LabVIEW or LabWindows with a simple command-line interface from any terminal window.

Please note that the cable for connecting this heater controller to a heating element is not provided. The TC200 uses a Hirose connector to read the temperature of the heating element and supply current. For the pin assignments needed to adapt the TC200 to your heater, please see the Pin Diagrams tab.

The unit also includes an auxiliary output for use with our GCH25-75 Reference Cell Oven. This auxiliary connection provides an unregulated output current that is proportional to the current supplied by the main output. Please see chapter 11 of the TC200 manual for more details about this feature.

The TC200 is shipped with a 120 VAC power cord for use in the US while the TC200-EC is shipped with a 230 VAC power cord for use in Europe. If you require a power cord for another country, please contact your local sales office.
