module functions

The Trainnet® Power Input Unit (PIU) is used to pass train battery voltage to the Trainnet® PSV module, thus powering the entire Trainnet® systems.


key features

The Trainnet® PIU input voltages can be 24 V DC (PIU2056A), 24 to 36 V DC (PIU4233A), 36 to 52 V DC (PIU2510A), 48 to 110 V DC (PIU4234A), 72 V DC (PIU2280A) or 110 V DC (PIU2219A). A Trainnet® PSV with a similar input voltage must be selected.


options

Isolated DC Converter Output: An isolated DC/ DC converter may be installed as an option to provide power to any external equipment. If required, the output voltage may be switched off during the system reset in order to force hard-resets of external equipment. Currently available PIU modules with DC Converter Ouput are listed in the table below. We can also provide you with another versions upon request.

Vehicle Identification Unit (VIU): The Trainnet® VIU (Vehicle Identification Unit) has the functionalities of the Trainnet® PIU, and in addition, provides an interface for Electronic Serial Number (ESN). An Electronic Serial Number (ESN) dongle can be connected to VIU for device identification and configuration. There are VIU versions for 24 V DC (VIU3688B) and 110 V DC (VIU2336B) input voltages.
