transCon Knoten transparent_32x32

Automation-, Control- and I/O System

transCON is an Automation-, Control- and I/O System, developed for applications with high requirements on technology and environment, particulary on vehicles.

transCON meets the European standards for electronics on rolling stock
EN 50 155 (Tx -40°C bis 70°C) / mechanics, temperature
EN 50 121-3-2 / Electromagnetic

In addition transCON is GL certified (ship approval Germanischer Lloyd, Environmental Category C, EMC1)

Power Supply

The module generated from the unregulated input voltage of 24 VDC the internal electronics voltages 5 VDC and 3.3 VDC. The supply the modules of the node are via the internal GREENBUS.


Bus Coupler

The bus coupler processes the data of the I/O modules and establishes the link to the CAN environment.



The PLC is a computer system that is suitable for railway applications with the Linux operating system. The user programming is done under CoDeSys IEC 61231-3.


Binary Input Module

The module offers 8 binary inputs. The continuous input current of 7mA guarantees a high level of signal reliability. Due to the potential-free design, the inputs can be switched in series.


Binary Output Module

The module offers 8 binary outputs. The maximum output load is 1A/ channel at 24V DC. Due to the potential-free design, the outputs can be switched in series. An external power supply for the electrically isolated circuits is not necessary.


Analogue Module

The module offers 4 analogue inputs and 2 analogue outputs for standard voltages and currents ±10 V; 0-10 V/ 0(4)-20 mA. The voltages and currents have a common ground.


Temperature Module

The module offers 4 analogue inputs for measuring temperature via PT100 elements. The inputs have a common ground. The temperature measuring range covers from -50 °C to 450 °C. The measurement is carried out in 2 and 4 conductor technology.



Continuation of the former product range ricosTP of Wieland Electric until 31.12.2017.
