Automation Controller

The Automation Controller „AuCo“ is a central control unit with several pre-installed digital interfaces and communication devices for minor automation applications.

The interfaces are:

  • Digital interface for safety control
  • RWM driver for DC motors
  • Digital and analog interfaces to multiple devices
  • Digital inputs and outputs for automation devices
  • Ethernet interface for connecting a computer via REST-API
  • CAN interface for basic CAN communications
  • Serial interface for diagnostic purposes

A typical application can be the control of a marking laser with parts’ handling.


The compact design offers connecting with the individual actors via direct cable connections so that constructing an electrical cabinet is not necessary. Being individually programmable, the AuCo provides multiple and fast control and communication functions.
The efficient interface to our software LisRT V3 makes the combination of these two products a flexible automation tool.

Software interfaces

The AuCo is programmed in C as embedded system. The basic functions of all interfaces and automation functions as well as communication functions are pre-installed. Therefore the software design must only be realized in a periodic form, similar to PLC programming.
However, the AuCo can also be used in combination with a PC application like LisRT V3 where the requested functions are programmed in Python. Then the Automation-Controller serves as peripheral component for inputs and outputs. For more information please visit www.LisRT.de

Switch-off and discharge unit

When testing power electronics with high DC values it is necessary to make sure that the test circuit and the DUT are de-energized at the end of the test. For this purpose, Löhnert Elektronik developed a switch-off and discharge unit which ensures the safe  switching off and monitoring of DC circuits with 15 V DC up to max. 750 V DC and max. 60 A DC.

  • Safe switch-off and discharge of DC circuits
  • Voltage range from 15 V DC up to max. 750 V DC
  • Current range from 1 A to 60 A
  • Application: Switch-off and short-circuiting unit for DC link test

Automotive Run-In Controller

The Run-In controller from Löhnert Elektronik is designed to test electronic control units (ECUs) under simulated environmental conditions and has been developed specifically for the automotive sector. The Run-In test identifies ECUs that are faulty due to being subject to high temperatures and load fluctuations over a prolonged period of time.

  • Interface connection and monitoring of electronic modules
  • UUT (unit under test) communication via CAN
  • up to 3 UUT's simultaneously
  • Main application: Stress endurance run of automotive control units (ECUs)
