SEM206TC Temperature Transmitter for Thermocouples, PC Programmable

The SEM206TC is our entry level PC programmable temperature transmitter. It accepts most common thermocouple sensors and converts the sensor output to a standard industrial 4 to 20mA transmission signal.

PC configuration allows the user to select range, units and burnout direction, without requiring calibration equipment. Configuration is performed quickly using our new USB port driven configurator by simply connecting two clips to the SEM206TC loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use.

However, if you already know the temperature range you require, we can  configure the product for you at no extra cost.


Suitable for K, J, N, E, T, R, S Thermocouples plus mV
Isolated input to output
Over range LED indication
