Short description
The TM 2xx/A series consists of temperature measurement modules that can be directly attached to CPU
modules and operated with all product lines of the KEBA control system by means of bus couplers.
TM 220/A, TM 240/A
Analog input modules TM 220/A and TM 240/A enable the direct connection of thermoelements (2-
conductor technique). The calibration and linearization of the temperature values takes place via a
microcontroller. A sensor failure, should it occur, is reported to the higher-level central module and can
be evaluated in the application.
Two operating modes are supported:
• Display of the actually measured temperature (standard mode)
• Display of the measured voltage in μV
Cold junction compensation can occur via internal temperature measurement at the terminals of the
module or optionally with the aid of external sensor TE 220/A (external terminal temperature
compensation).
