Modern commercial vehicles are often equipped with the Characteristics

MTCO 1324 tachograph which calculates the speed via the intelligent motion sensor KITAS and transfers the information per CAN Bus to an instrument cluster. If here is no duty to use the tachograph, e.g. within the export, it is possible that the simple tachometer simulator unit TSU 1391 is used instead of the MTCO 1324. Concerning the vehicle electrical system the TSU 1391 works similar to the MTCO 1324 and governs all necessary data to achieve a correct display of speed, power and time. As result the vehicle electrical system can be comple- ted cost efficiently.

Alternatively the TSU 1391 works together with the modern intelligent motion sensor or the conventional sensor KITAS such as type 2159. Via the testing- and programming interface it is possible to program specific figures including size, time and manufacturer`s instructions.

The internal running time (Real Time Clock RTC) is battery- buffered and can be changed by the driver using two buttons located on the front panel.
In order to drive peripheral devices the well known electrical outputs such as v-pulse and 4 pulse/m are continuously available.
