Railway safety

Rail transport continues to grow. Longer, heavier, faster but all safe.

 

Interface module HL 3094N

 

More and more people and goods are being transported by rail. This also increases the demands on technology and safety. In order to meet the high safety standards in railway technology according to
EN 50155, relays with forcibly guided contacts according to DIN EN 61810-3 are used.

 

Relays with forcibly guided contacts have larger contact opening distances by default. This allows switching of higher direct currents. Such a feature is necessary for use on rail vehicles according to EN 50155. In addition, the forced guidance of the contacts with the diagnostic option via the NC contact also offers the possibility of using the relay in safety-relevant circuits.

 

The module is simply integrated into the system in the switch cabinet on the DIN rail and placed in front of an electronic controller, for example, in order to be able to switch a higher current. The interface modules are used in safety circuits for dead man's circuits, emergency stop circuits and door opener systems.

 

Cage clamp terminals ensure constant contact forces and vibration-proof connection technology. The
HL 3094N is available in a soldered version but also with a plug-in socket for the safety relay OA 5601.
