The Allen-Bradley 2080-TC2 provides two thermocouple measurement channels for compatible Micro800 programmable controllers. Each channel can be configured for its own supported sensor type and filter settings, allowing two separate process temperatures to be monitored.
The module supports J, K, N, T, E, R, S and B thermocouples. This selection accommodates a variety of industrial temperature measurement applications, with each sensor type having its own specified temperature and accuracy ranges.
With 14-bit analog-to-digital resolution, the module converts thermocouple signals into digital temperature data for the connected controller. Rockwell Automation specifies ±1.0°C measurement accuracy at 25°C under applicable conditions, with accuracy also dependent on sensor type and update rate.
The 2080-TC2 uses an external NTC thermistor for cold junction compensation across both input channels. The thermistor connects to terminals A3 and B3 and must be installed correctly to obtain valid compensated thermocouple measurements.
Open-circuit, overrange and underrange detection help identify disconnected sensors and readings outside the configured thermocouple measurement range. Corresponding diagnostic information can be accessed through compatible controller variables.
The plug-in design installs directly into a supported Micro800 controller slot without requiring a separate Bulletin 2085 expansion I/O assembly. Configuration through Connected Components Workbench or supported FactoryTalk Design Workbench software helps integrate temperature feedback into PLC applications.

What is the Allen-Bradley 2080-TC2?
It is a Rockwell Automation Micro800 plug-in temperature measurement module providing two non-isolated thermocouple input channels for compatible PLC controllers.
How many thermocouple inputs does the module have?
The module provides two input channels, Channel 0 and Channel 1. Each channel can be configured for a supported thermocouple type and measurement update setting.
Which thermocouple types are supported?
The 2080-TC2 supports Type J, K, N, T, E, R, S and B thermocouples. The default configuration is Type K.
What is the measurement resolution?
The module provides 14-bit analog-to-digital resolution. The accuracy and usable temperature range depend on the thermocouple type, temperature and configured conversion rate.
What is the specified measurement accuracy?
Rockwell Automation specifies ±1.0°C at 25°C under applicable conditions. The separate cold junction compensation error is ±1.2°C at 25°C, and sensor tolerance and installation conditions can contribute additional measurement error.
What is the measurement range for a Type K thermocouple?
The published Type K measurement range is -270 to +1370°C. The manufacturer identifies a narrower -200 to +1300°C range for the specified ±1.0°C accuracy conditions and applicable conversion rates.
Does the 2080-TC2 require a cold junction compensation sensor?
Yes. An external NTC thermistor is used for cold junction compensation. The manufacturer describes this component as supplied with the module and specifies its installation between terminals A3 and B3.
Can two different thermocouple types be connected simultaneously?
Yes. Each input channel is individually configurable, so the two channels can use different supported thermocouple types within the manufacturer's wiring and operating requirements.
Which Micro800 controllers are compatible?
The module is intended for supported Micro820, Micro830, Micro850 and Micro870 controller configurations with compatible plug-in slots. Confirm the exact controller catalog number and software compatibility before installation.
Can the module be used for PID temperature control?
Yes. The module supplies thermocouple measurement data that a compatible Micro800 controller can use in a configured PID temperature control application. It is a measurement module, not a standalone temperature controller.
Does the 2080-TC2 support RTD sensors such as Pt100?
No. The 2080-TC2 is intended for thermocouple sensors. Rockwell Automation provides the separate 2080-RTD2 module for supported resistance temperature detector inputs.
Are the two thermocouple channels electrically isolated?
No. Rockwell Automation identifies the 2080-TC2 as a non-isolated thermocouple input module. Sensor grounding, shielding and installation methods must account for the shared electrical characteristics.
Does the module support open-circuit detection?
Yes. The module reports open-circuit, overrange and underrange conditions through corresponding diagnostic information. Rockwell Automation specifies an open-circuit detection time ranging from 8 to 1515 ms.
Does the module require an external 24 VDC power supply?
The plug-in receives its operating power from the compatible controller interface. Rockwell Automation specifies a current consumption of 40 mA at 3.3 VDC.
Can the 2080-TC2 be replaced while the controller is powered?
No. Removal and insertion under power are not supported. Disconnect the appropriate power sources and follow the manufacturer's installation procedures before replacing the module.
What software is used to configure the module?
The module can be configured through compatible Connected Components Workbench or FactoryTalk Design Workbench software. Supported settings include thermocouple type and ADC update or filter frequency for each channel.
What should be checked before ordering?
Confirm catalog number 2080-TC2, two non-isolated thermocouple channels, required J/K/N/T/E/R/S/B sensor compatibility, 14-bit resolution, compatible Micro800 controller and plug-in slot, CJC thermistor availability, temperature measurement range, software configuration requirements and correct field wiring. Verify the manufacturer's current installation documentation before commissioning.
