Tab. 4.3: Railway Safety Appliance Standards Regulations

Electronic appliances in railway vehiclesCSN EN 50155 ed. 2nd: 2002. art. 10.2.8.2 CSN EN 50121 art. 7: tab. 3 and 4
EMC (Electromagnetic Compatibility)CSN EN 50121-3-2 art. 8
Vibrations and beatsCSN EN 61373

Upon installation in railway vehicles, where there is a high level of interference, special attention should be given to the communication interface. In such cases it is necessary to use shielded cables and correctly grounded twisted pairs.

[Note]Note

The standard CSN EN 50155 (Electronic equipment in railway vehicles) does not apply to analog inputs and outputs and to the interface in the 1st slot. Therefore they are not recommended for use, and in an environment specified according to this standard no warranty applies to their use.
