module functions

The Trainnet® RIOM enables data input and output within the vicinity of the I/O sources.

It is used as an alternative to connecting I/O sources directly to the train computer (e.g. VCU) and it can lead to reduced cabling and thus cost savings.

key features

The RIOM supports both analogue and digital inputs/outputs. Most Trainnet® I/O module can be used, including Analogue Input Module (AIM), Analogue Output Module (AOM), Digital Input/Output Module (DIO), Digital Relay Output (DRO) and Pt-100 temperature Sensor Input (PTI). You can find out more about these modules by reading the dedicated datasheets or by contactinga a Sales representative at EKE..

The Trainnet® RIOM includes an interface module used for the communications with the train computer. It is also equipped with an independent power supply (Trainnet® PSR module).


 The Trainnet® Ethernet RIOM is equipped with one Ethernet interface for connectivity with the train computer (CPE module).
The Trainnet® MVB RIOM uses MVB interfaces to connect with the train computer. By default, the MVB physical interface is Electrical Medium Distance (EMD) with two sub D-9 connectors. Electrical Short Distance with optical isolation (ESD+) mediums are available upon request.

Number of modules:
 In its most compact version, RIOM can use up to 8 EKE Trainnet® I/O modules and be fitted into a 44TE rack.
A 84TE rack version is also available as an option to fit up to 18 I/O modules.
