Short Description
The ESX®-LTplus is a recent development of the Sensor-Technik Wiedemann Group. It is a 16 Bit based controller, which is qualified for applications under the rough conditions in off highway vehicles and mobile machines.
The freely programmable electronic control unit offers a large number of inputs and outputs in in a compact housing. As with the ESX® and ESX®-LT, the housing is die-cast aluminium.
