I/O Units with CAN

RRC-xxx are remote I/O units designed and optimized to control rolling stock. Units communicate with other parts of TCMS through CANopen DS 401 protocol. The units meet the requirements of EN 50155 (Electronic equipment used on rolling stock) class TX.

The CAN connectors are concatenated (simpler cabling). The RRC-KM plug-in module is used to adjust the rate of communication and the unit address. This can be a part of cabling (the providing so-called node geographic configuration). This solution minimizes mistakes in the unit configuration when servicing or making a replacement. The signal connectors used are of the type WAGO X-COM.
